AbstractThe haphazard and irrational use of chemical pesticides has led to pest resurgence and pesticide resistance, posing a significant challenge in the management of economically important pests. Farming systems built on integrated pest management (IPM) can minimize the use of chemical pesticides and secure soil, plant, and human health by controlling pests at the same time. Bactrocera cucurbitae is a serious pest of cucurbitaceous crops including more than other 70 hosts. Though various control strategies have been developed against melon fruit flies, fewer efforts have been paid to establish effective and efficient integrated pest management programs. This review provides an overview of the life cycle and behaviour of melon fruit fly as well as a detailed analysis of the various IPM strategies that have been developed for their control. These strategies include cultural practices, such as weeding, removal of alternate hosts, and field sanitation, biological control methods such as use of natural enemies, and entomopathogenic fungi (Beauveria bassiana, B. pseudobassiana), use of botanicals (neem, jholmol), and chemical control measures, such as the use of pesticides.Keywords: Bactrocera cucurbitaeIPMcontrolyield lossmanagement AcknowledgmentsWe would like to thank our parents, friends, and professors from Agriculture and Forestry University who helped directly and indirectly during the process of manuscript preparation.Authors’ contributionsPramod Gyawali analysed the data and prepared the manuscript.

摘要化学农药的随意和不合理使用导致害虫死灰复燃和抗药性,对重要经济害虫的治理提出了重大挑战。建立在病虫害综合管理(IPM)基础上的农业系统可以最大限度地减少化学农药的使用,同时通过控制病虫害来保护土壤、植物和人类健康。葫芦小实蝇是葫芦科作物的严重害虫,有70多种寄主。尽管人们已经开发出各种防治瓜类果蝇的策略,但建立有效和高效的害虫综合治理方案的努力却很少。本文综述了甜瓜果蝇的生命周期和行为,并详细分析了各种防治策略。这些策略包括培养方法,如除草、去除交替寄主和现场卫生,生物控制方法,如使用天敌和昆虫病原真菌(白僵菌、假球孢白僵菌),使用植物药物(印楝、苦艾草),以及化学控制措施,如使用杀虫剂。感谢我们的父母、朋友和农林大学的教授,他们在稿件的准备过程中给予了直接或间接的帮助。作者的贡献:spramod Gyawali分析了数据并准备了手稿。所有其他共同作者都对手稿进行了严格的审查,最终版本被所有共同作者接受出版。公开声明共同作者声明本论文的发表不存在利益冲突。

AbstractAfrican rice gall midge (AfRGM), Orseolia oryzivora (Diptera: Cecidomyiidae) is a significant pest of rainfed and lowland rice that causes about 25% to 100% yield loss. The effectiveness of chemical insecticides has been compromised due to insecticide resistance and concerns over their environmental impact, which necessitated an alternative approach that is safe and more sustainable. The study aimed to determine the effectiveness of Entomopathogenic fungi (EPF), Metarhizium anisopliae and Beauveria bassiana in controlling AfRGM on four popular rice cultivars under screenhouse conditions at AfricaRice/IITA, Ibadan, Nigeria. The experiment was laid out in a 4 x 3 factorial fitted in a completely randomized design (CRD) in three replications. Results showed that although both fungi significantly reduced AfRGM tiller infestation, the degree of reduction varied with the specific fungus and rice variety grown. Beauveria bassiana exhibited better control of AfRGM on FARO 37 and FARO 44 varieties, while M. anisopliae was more effective on FARO 66 and FARO 67 varieties. Tiller infestation had a significant negative correlation with grain yield (r= − 0.87, R2 = 77). The study also indicated that the two fungi strains had no harmful effect on the chlorophyll content and positively influenced agronomic traits and grain yield.Keywords: Entomopathogenic fungiMetarhizium anisopliaeBeauvaria bassianaAfRGMricetiller infestation AcknowledgementsThe authors gratefully appreciate Dr Douro Kpindou for providing the EPF isolates from IITA laboratory, Benin Republic and Mr. Adebayo Kehinde for technical assistance.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementData will be made available on request.
摘要非洲稻瘿蚊(Orseolia oryzivora,双翅目:瘿蚊科)是旱作水稻和低地水稻的重要害虫,可造成25% ~ 100%的产量损失。由于杀虫剂抗药性和对其环境影响的担忧,化学杀虫剂的有效性已经受到损害,因此需要一种更安全、更可持续的替代方法。本研究旨在确定昆虫病原真菌(EPF)、绿僵菌(Metarhizium anisopliae)和球孢白僵菌(Beauveria bassiana)在尼日利亚伊巴丹的AfricaRice/IITA筛选条件下对4种常用水稻品种的防治效果。试验采用完全随机设计(CRD),采用4 × 3因子拟合,共3次重复。结果表明,虽然两种真菌均能显著减少AfRGM分蘖侵染,但减少程度因真菌和水稻品种而异。AfRGM对FARO 37和FARO 44的抑菌效果较好,对FARO 66和FARO 67的抑菌效果较好。分蘖侵染与籽粒产量呈显著负相关(r= - 0.87, R2 = 77)。研究还表明,这两种真菌对叶绿素含量没有有害影响,对农艺性状和籽粒产量有积极影响。作者感谢Douro Kpindou博士提供的来自贝宁共和国IITA实验室的EPF分离株和Adebayo Kehinde先生的技术支持。披露声明作者未报告潜在的利益冲突。数据可用性声明数据可应要求提供。

AbstractRugose spiraling whitefly (Aleurodicus rugioperculatus Martin) has become a major pest of coconut in Bangladesh. To assess farmers’ knowledge on host and management approaches of this pest, a survey of 240 farmers was conducted in eight districts of Bangladesh. Farmers noticed an expanding dispersion of this pest in Bangladesh since 2019. Among all the districts examined, Cox’s Bazar district was highly infested. Farmers mainly cultivated local coconut varieties in their homesteads. Forty percent (40%) of the farmers among all districts estimated that the pest reduced coconut yield to more than half. Only 1% of all farmers knew about all life stages of the pest. Consultation with extension officers significantly improved farmers’ knowledge of the pest. Summer was the peak season for the whitefly infestation. Farmers identified 22 hosts of the pest and almost four out of ten (40.4%) applied management methods against the pest. Among them, 22% used chemical methods, 42% used non-chemical methods, and 24% used both methods. Farmer’s types, purposes, and knowledge influenced their management approaches.Keywords: Coconut pestdispersaldamage severityyield lossmanagement methods AcknowledgementsThe authors gratefully acknowledge the Sylhet Agricultural University Research System (SAURES) and the Ministry of Science and Technology, University Grants Commission of Bangladesh (UGC) for providing the funds for our study.

AbstractStriga hermonthica is fast spreading in the Nigerian savanna and is predicted to encroach into the rainforest part of the country soon. S. hermonthica seedbanks in savanna soils have continued to rise due to poor agronomic practices by smallholder farmers. Considering differences in soil, climate, and agronomic practices within the savanna endemic agroecology, the severity of the infestation of S. hermonthica has varied from one location to another. Hence, there is a need to model a site-specific management approach for S. hermonthica in Nigeria. This review aims to understand the state-of-the-art management of S. hermonthica in Nigeria’s upland rice fields and further harmonize potential management approaches. Based on studies conducted in Nigeria, reducing S. hermonthica parasitism over a long-term period in the Savanna ecology of Nigeria implies the rotation of upland rice with trap crops, and enhancement of nitrogen fertility in farmers’ fields, combined with the use of seed-treated resistant or tolerant cultivars. In practical terms, farmer’s-research engagement in the long term is pertinent to reduce the severity of S. hermonthica in threatened areas.Keywords: Striga hermonthica (Del.)

摘要在尼日利亚的热带稀树草原上,刺蒺藜正在迅速蔓延,预计不久将侵入该国的热带雨林地区。由于小农的不良农艺做法,热带草原土壤中的美洲月季种子库继续增加。考虑到热带稀树草原特有农业生态学中土壤、气候和农艺实践的差异,红月杉侵染的严重程度因地而异。因此,有必要为尼日利亚的S. hermonthica建立一个具体地点管理方法的模型。本综述旨在了解尼日利亚旱地稻稻稻的最新管理方法,并进一步协调潜在的管理方法。根据在尼日利亚进行的研究,在尼日利亚的热带草原生态中,长期减少hermonthica的寄生意味着旱稻与陷阱作物轮作,提高农民田地的氮肥肥力,并结合使用经过种子处理的抗性或耐受性品种。实际上,从长远来看,农民的研究参与与减少受威胁地区的红月牙曲霉的严重程度有关。关键词:刺甲声明作者声明在本文中无利益冲突。

AbstractThe silver leaf whitefly, Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), stands out as a highly destructive insect in temperate, tropical, and subtropical regions, inflicting extensive damage to agricultural crops worldwide. Its impact resonates in India, where it has emerged as a formidable pest. Moreover, the excessive use of chemically-derived pesticides has led to the emergence of insect-resistant strains, resulting in environmental pollution and endangering human health. The use of natural enemies is a sustainable and environmentally safe alternative management tactic. The predation potential of green lacewing, Chrysoperla zastrowi sillemi Esben-Peterson (Neuroptera: Chrysopidae) on eggs, nymphs and adults of B. tabaci infesting parthenocarpic cucumber grown under polyhouse has been examined here. On cucumber plants, three releases of 2nd instar C. zastrowi sillemi larvae (at one, two and three larvae/plant) were made at 7 days intervals. The release of three larvae/plant resulted in significantly higher predation rate on whitefly population (58.6% on egg, 61.0% on nymph and 32.3% on adult stage of the whitefly) than two or one green lacewing larvae/plant (56.3% on egg, 58.3% on nymph and 30.4% on adult stage of the whitefly & 49.9% on egg, 51.0% on nymph and 24.6% on adult stage of the whitefly, respectively). Significantly higher yields of cucumber were recorded from plots with the release rate of three larvae per plant (2047.9 g/plant). Augmentative biological control of B. tabaci under polyhouse conditions with three weekly releases of 2nd instar C. zastrowi sillemi larvae at three larvae per plant can effectively manage whitefly infestation on parthenocarpic cucumber under polyhouse condition.Keywords: Biological controlmarketable fruit yieldpredation efficiencyprotected structuresvegetable cropwhitefly AcknowledgementsThe authors are grateful to the Dr. Pardeep Kumar Chhuneja, Professor of Entomology and Head, Department of Entomology, Punjab Agricultural University, Ludhiana, India, for providing infrastructure and necessary facilities during the study.

Augmentative biological control of B. tabaci under polyhouse conditions with three weekly releases of 2nd instar C. zastrowi sillemi larvae at three larvae per plant can effectively manage whitefly infestation on parthenocarpic cucumber under polyhouse condition.Keywords: Biological controlmarketable fruit yieldpredation efficiencyprotected structuresvegetable cropwhitefly AcknowledgementsThe authors are grateful to the Dr. Pardeep Kumar Chhuneja, Professor of Entomology and Head, Department of Entomology, Punjab Agricultural University, Ludhiana, India, for providing infrastructure and necessary facilities during the study.

AbstractCashew nut (Anacardium occidentale L.) farmers are facing challenges producing quality nuts due to inadequate knowledge of cashew insect pests and their management practices in Bangladesh. For this reason, a survey of 144 cashew farmers was conducted from June 2020 to December 2022. Tea mosquito bug (70.1%), cashew stem and root borer (52.8%), and apple and nut borer (45.8%) were the top-ranked among 21 insect pest species of cashew. The highest insect pest infestation was observed in the tender leaves (49.8%). Overall, 56.3% farmers noticed 11–20% yield losses caused by insect pests, while 9% of the farmers believed that yield losses could be more than 40% in cashew orchards. Although physical (7.7%) and mechanical (7.6%) pest management tactics, like hand-picking, use of coal tar, kerosene, and yellow sticky traps were used to control pests, most farmers (84.7%) relied on chemical pesticides. Young and educated farmers were interested in non-chemical pest management options compared to their counterparts. Farmers believed that intercultural operation like weeding and pruning could reduce insect pests in cashew orchards.Keywords: Cashewfarmersinsect pestssurveymanagementBangladesh AcknowledgmentsThe authors gratefully acknowledge the Ministry of Science and Technology, University Grants Commission of Bangladesh (UGC) for their financial support that enabled the successful completion of this work.

摘要孟加拉国腰果(Anacardium occidentale L.)农民由于缺乏对腰果害虫的认识和管理措施,在生产高质量腰果方面面临挑战。为此,从2020年6月到2022年12月,对144名腰果农民进行了调查。在腰果的21种害虫中,茶虫(70.1%)、腰果根茎蛀虫(52.8%)、苹果和坚果蛀虫(45.8%)位居首位。病虫害以嫩叶侵染最多(49.8%)。总体而言,56.3%的农民认为虫害造成了11-20%的产量损失,9%的农民认为腰果果园的产量损失可能超过40%。尽管采用了物理(7.7%)和机械(7.6%)虫害管理策略,如手工采摘、使用煤焦油、煤油和黄色粘捕器来控制害虫,但大多数农民(84.7%)依赖化学农药。与其他农民相比,受过教育的年轻农民对非化学有害生物管理选择更感兴趣。农民认为,除草、修剪等跨文化操作可以减少腰果果园的虫害。作者感谢孟加拉国科学技术部、大学教育资助委员会(UGC)的资金支持,使这项工作得以顺利完成。作者还感谢腰果农民和孟加拉国班达班地区的副助理农业官员(SAAO)在本研究过程中的奉献和合作。最后但并非最不重要的是,我们要感谢美国北达科他州立大学“作家中心”(CFW)的英语语言检查和语法纠正。作者贡献本研究由所有作者合作完成。作者dr .

AbstractThe insecticidal efficacy of four species of Trichoderma genius (T. harzianum, T. citrinoviride, T. viride and T. asperellum) and Metarhizium anisopliae was assessed against Callosobruchus maculatus and C. chinensis on cowpea seeds at concentrations of 2.0 × 106, 2.0 × 107, 2.0 × 108 and 2.0 × 109 conidia/kg. The adult mortality was counted 3 and 7 days after treatment while progeny and seed weight loss were recorded after 45 days. After 7 days, all fungal strains caused significant adult mortality of both insects particularly at 2.0 × 109 spores/kg. Metarhizium anisopliae and T. citrinoviride were the most effective fungi inducing 95 and 93.2% mortalities of C. chinensis at 2.0 × 109 spores/kg, respectively. Callosobruchus chinensis was slightly more susceptible to the fungal strains than C. maculatus. Furthermore, the fungal strains at the highest concentration caused a significant reduction in F1 progeny of both insects. After 45 days, T. harzianum at 2.0 × 109 spores/kg showed the highest protection of cowpea seeds against C. chinensis with weight loss of 6.5%. These findings indicate that the five fungal strains could be implemented in integrated pest management programs of these insects.Keywords: Fungal strainsinsecticidal efficacybiological controlcowpea seedsBruchinae Disclosure statementNo potential conflict of interest was reported by the author(s).
摘要以2 × 106、2 × 107、2 × 108和2 × 109分生菌/kg浓度的豇豆种子为研究对象,评价了4种黑霉、黄绿霉、绿霉和曲霉的杀虫效果。处理后第3天和第7天分别记录成虫死亡率,45天后记录子代和种子失重。7 d后,所有菌株对两种昆虫的成虫死亡率均有显著影响,特别是在2.0 × 109孢子/kg时。在2.0 × 109孢子/kg时,绿僵菌和柠檬酸绿僵菌的死亡率分别为95%和93.2%。中国Callosobruchus对真菌菌株的敏感性略高于maculatus。此外,在最高浓度下,真菌菌株显著降低了两种昆虫的F1后代。处理45 d后,2.0 × 109孢子/kg浓度的哈兹坦菌对豇豆种子的保护效果最好,减重6.5%。研究结果表明,这5株真菌可用于害虫综合治理。关键词:真菌菌株;杀虫效果;生物防治;豇豆种子;

AbstractBotanical oils are considered ecofriendly compounds with insecticidal characteristics. In this study, the effects of basil (Ocimum basilicum), camphor (Cinnamomum camphora), cinnamon (Cinnamomum verum), lemon (Citrus limon), clove (Syzygium aromaticum), ginger (Zingiber officinale), black pepper (Piper nigrum), and orange (Citrus sinensis var balady) oil extracts on the survival of four entomopathogenic nematode strains belonging to the Steinernema and Heterorhabditis genera, as well as their impacts on Rhynchophorus ferrugineus egg hatching and larvae, were assessed. The results for the camphor, lemon, black pepper, and orange oils were promising as 50 μL/mL of each resulted in 0%, 0%, 16%, and 0% hatchability for the R. ferrugineus eggs, respectively. Furthermore, the mortality of R. ferrugineus larvae was up to 95% with the similar concentrations and an exposure time of 48 h, for the other investigated oils. Various morphohistopathological alterations were found in the cuticle; outer cuticle folds swelling or shrinkage and subcuticular muscle degeneration, as well as midgut; fat globules in the epithelial lining with marked degeneration and/or necrosis, of the R. ferrugineus larvae when compared with those of controls replicates. Mortality percentage of infective juveniles (IJs) of Steinernema carpocapsae (S2) was significantly lower than Heterorhabditis marelatus (D1), Steinernema riobravae (Sr) and Steinernema carpocapsae (All) when using camphor oil compared to the other oils (50%). From the obtained observations on oils lethal effects, the target of developing integral biocontrol product formulated from combinations of essential oils and nematode with insecticidal properties against R. ferrugineus (not nematode survival) is possible; a sustainable and ecofriendly product for pest management.Keywords: Red palm weevilSteinernema spp.Heterorhabditis spp.essential oilintegrated pest management AcknowledgmentThe authors would like to thank the field investigators, who helped in collecting specimens in investigated locality.

AbstractThe Colorado potato beetle (CPB) is a serious pest of potato in China. To determine the effect of individual-rearing and group-rearing on its population growth and development, we studied its life tables and projected its population growth using the TWOSEX-MS Chart and TIMING-MS Char programs. Results showed that individually-reared CPBs were significantly better than that of group-reared CPBs, in terms of intrinsic rate of increase (0.07), finite rate of increase (1.07), net reproductive rate (39.93), and gross reproductive rate (221.23) compared to that of group-reared treatment (0.05; 1.05; 10.84; and 58.77). Additionally, individually-reared CPB populations had faster development, characterized by shorter generation cycles, and higher female survival rates, which produced more offspring per unit time, compared to the group-reared CPB population. However, in potato fields, the CPB are mostly found in groups and therefore the group-rearing method should be more effective for prediction and possible management of CPB populations. This study serves as a reference for an effective and biological prevention and control of the CPBs.Keywords: Colorado potato beetlesage-stage two-sex life tableindividual-rearinggroup-rearing AcknowledgmentsThe authors thank J.

摘要科罗拉多马铃薯甲虫(CPB)是中国马铃薯的严重害虫。为了确定个体饲养和群体饲养对其种群生长和发展的影响,我们研究了其生命表,并使用two性别- ms图和TIMING-MS Char程序预测了其种群增长。结果表明:个体饲养的CPBs内在增殖率(0.07)、有限增殖率(1.07)、净繁殖率(39.93)和总繁殖率(221.23)均显著优于群养处理(0.05;1.05;10.84;和58.77)。此外,个体饲养的CPB种群发育更快,代周期更短,雌性存活率更高,单位时间内产生的后代更多。然而,在马铃薯田中,CPB大多是群居的,因此群体饲养方法对CPB种群的预测和可能的管理应该更有效。本研究可为CPBs的有效生物防治提供参考。致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢致谢同时,他们感谢LetPub (www.letpub.com)在本文准备过程中的语言编辑。作者贡献:concepalization, CL和JHL;形式分析,HHS;资金获取,CL;调查,JHL;方法学、CL和JHL;工程管理学院;资源,CL;写作:原始草案准备,卫生与公众服务部;写作:审编,CL。所有作者都阅读并批准了最终的手稿。披露声明作者报告无利益冲突。数据可用性声明支持本文结论的数据包含在本文及其附加文件中。本研究得到国家重点研发计划项目(2021YFD1400200)的支持;国家自然科学基金(31660545);中国博士后科学基金(2017M613305XB);农业农村部西北荒漠绿洲作物有害生物综合治理重点实验室(kfjj20105)。

To determine the effect of individual-rearing and group-rearing on its population growth and development, we studied its life tables and projected its population growth using the TWOSEX-MS Chart and TIMING-MS Char programs. Results showed that individually-reared CPBs were significantly better than that of group-reared CPBs, in terms of intrinsic rate of increase (0.07), finite rate of increase (1.07), net reproductive rate (39.93), and gross reproductive rate (221.23) compared to that of group-reared treatment (0.05; 1.05; 10.84; and 58.77). Additionally, individually-reared CPB populations had faster development, characterized by shorter generation cycles, and higher female survival rates, which produced more offspring per unit time, compared to the group-reared CPB population. However, in potato fields, the CPB are mostly found in groups and therefore the group-rearing method should be more effective for prediction and possible management of CPB populations. This study serves as a reference for an effective and biological prevention and control of the CPBs.Keywords: Colorado potato beetlesage-stage two-sex life tableindividual-rearinggroup-rearing AcknowledgmentsThe authors thank J.
