The banana fruit fly (Bactrocera musae Tryon), belonging to the family Tephritidae and subfamily Dacinae, is the main pest of bananas responsible for significant crop losses. In order to monitor the B. musae infestation, we collected banana fruit samples from four locations on the Gazelle Peninsula: Burit, Kereba, Vudal, and Vunapalading. On each field collection date, twelve banana bunches were chosen at random from the corresponding study sites. Following the removal of 100 individual fruits (fingers) from each fresh bunch at each study site, the fruits were weighed, thoroughly cleaned with rainwater three times, and then incubated in containers until the larval developmental stages were finished. When compared to the other three sites, the number of adults in the Kalapua bananas sampled from Burit was the highest. The banana fruits were divided into three main groups: “mature green”, “mature ripe”, and “immature green”. Mature green fruits produced a higher adult abundance than mature ripe fruits. Compared to the other two stages, immature green had the fewest adults. By fruit weight, Burit had the highest infestation (20.9%), while Vunapalading had the lowest (11.9%). After Kereba (14.7%), Vudal had the second-highest infestation (16.8%). Mature ripe fruit had the highest infestation (37.1%) by fruit weight, while immature green fruits had the lowest infestation (2.04%). A moderate level of infestation was observed in mature green fruits (17.1%). Regarding fruit count, the least infected fruits were immature green fruits (1.8%), moderately infected mature green fruits (17.0%), and highly infected mature ripe fruits (26.9%). Geographically, the Gazelle Peninsula has a Kalapua infestation level ranging from 11.9 to 20.9%, and a different maturity stage infestation level ranging from 2.04 to 26.9%. In general, the degree of infestation has escalated, and B. musae has established itself in the Gazelle Peninsula.

In Bangladesh, brinjal (Solanum melongena L.) is an important vegetable crop due to its year-round cultivation, high demand for consumption, and nutritional value. The main obstacle to the successful cultivation and production of brinjal is insect pests. The current study was carried out in the winter, when green leafhoppers (Amrasca biguttula biguttula), one type of sucking insect pest, are most prevalent. Early in the vegetative stage, an infestation of green leaf hoppers (GLH) was noted; as the canopy size increased, so did their numbers. The consumption of brinjal with its peel poses a health risk due to possible contamination with toxic chemical insecticides. We assess a few non-toxic or minimally toxic bio-insecticides against GLH in order to tackle this crucial problem. Fizimite, one of the bio-insecticides, was found to be effective against GLH in a sodium lauryl ether sulfate preparation. Fizimite decreased the amount of GLH in the plant by 85.8%, the amount of leaf infestation by 77.84%, and the amount of GLH-infected brinjal leaf abundance by 54.34%. But Voliam Flexi, a chemical control, was also discovered to be successful against GLH. Fizimite may therefore be a non-toxic, bio-rational substitute for Voliam Flexi, a synthetic, toxic medication used to control GLH.

An evaluation of various botanical insecticides to control Aphis gossypii and its impact on aphid population dynamics on chrysanthemum plants was investigated. In order to control A. gossypii on chrysanthemum, the effectiveness of several botanical insecticides extracted from Melia azedarach, Toona sinensis, and Chrysanthemum cinerariaefolium was investigated in the current study. The research was carried out in the experimental field of the Indonesian Ornamental Crops Research Institute under plastic house conditions. Five concentrations, i.e., 1.5, 2.0, 2.5, 3.0, and 3.5 g/L of three plant extracts, M. azedarach, T. sinensis, and C. cinerariaefolium, were sprayed on chrysanthemum cultivar White Fiji after 28 to 84 days after planting. A. gossypii had a dynamic population that changed according to the plant’s developmental stages. In vegetative growth, the alate adult and nymphal stages were dominant, and the population of nymphs increased along the plant ages. The insect colonized young leaf surfaces in the terminal apices. During the reproductive stages, the population of alate adults diminished, and the distribution of the insect extended to mature, old leaves, flower buds, and bloomed flowers. The application of several botanical insecticides revealed various responses of aphid populations. Among the tested insecticides, C. cinerariaefolium extract at 3.0 and 3.5 g/L demonstrated the highest average percentage efficacy (76 and 72%) and was the most consistent in suppressing the population. The results of this study indicate the potential efficacy of botanical insecticides against A. gossypii suggesting a different approach to efficient and environment-friendly chrysanthemum pest management.

Originally from Southeast Asia, the tiger mosquito (Aedes albopictus) is now found almost everywhere in the world. Additionally, it spread throughout all of Northeastern Italy’s cities, including Trento, and settled in the Alpine regions. The invasion of mountain regions in the Alps above 600 meters, which is generally thought to be the upper limit of Ae. Albopictus’s range, is confirmed for the first time in this note. We observed it in the summer of 2023 between 615 and 708 meters above sea level in the Trento region’s surrounding mountains, specifically in the Montevaccino and Sopramonte localities. The mosquito was caught using ovitraps, and by raising the eggs to adulthood in a lab, the species identification was verified. This finding heightens worries about how tropical insect species, which are favored by global warming, may invade the mountains and affect tourism.

The present study aimed to compare some commercial traps baited with ammonium carbonate for their efficacy in monitoring Bactrocera oleae (Rossi) and their selectivity toward beneficial insects, under the conditions of olive groves located in five Mediterranean countries (Greece, Italy, Lebanon, Spain, Tunisia). The selectivity of the devices was evaluated toward several groups of non-target insects, namely lacewings (Chrysopidae), hoverflies (Syrphidae), ladybirds (Coccinellidae), bees (Apoidea) and hymenopteran parasitoids. The following devices were compared: yellow sticky panel, green sticky panel, Jackson trap with different combinations of yellow and white colours of the device and/or the panel, and McPhail trap. In most cases, the McPhail trap and the yellow panel showed the highest efficacy in monitoring male and female B. oleae flies; however, the yellow panel was most attractive for some groups of non-target insects, particularly the hymenopteran parasitoids, whereas the comparative non-target effects were sitespecific for the other arthropod groups. In the case of Chrysopidae, McPhail caught more individuals than the other traps in Italy and Spain, whereas in Lebanon and Greece, the highest number of individuals was captured in the two sticky panels. Coccinellidae were found in very low numbers only in Lebanon on yellow panels. Syrphidae were captured mainly on sticky panels in Greece and Tunisia. Apoidea were found only on yellow panels in Lebanon. The choice between the McPhail trap and the yellow panel should be made on the basis of various evaluations carried out at the site, including operational ones.

The khapra beetle, Trogoderma granarium, poses a significant threat as a post-harvest pest in stored products and stands out as a crucial quarantine concern globally. Unlike many other stored product pests, this species proved challenging to manage using conventional insecticides and alternative non-chemical methods. The exploration of plant-based natural products, particularly essential oils, as alternatives arises in response to challenges associated with the prolonged use of synthetic insecticides. While essential oils show promising activity, their use encounters challenges associated with standardization. This study investigates the feasibility of employing some single chemical compounds widespread in several essential oils with insecticidal activity as candidate insecticides, specifically limonene and methyl salicylate in contact/fumigation bioassays toward T. granarium adults. The results showed that methyl salicylate caused a lethal time of 50% (LT50) at the dose of 1 mg after 7.40 hours of exposure. The LT50 calculated for limonene was 86.83 hours while positive control using deltamethrin, used at the recommended dose of the manufacturer, was 5.20 hours after exposure. These data suggest that methyl salicylate can be exploited as a candidate for further tests in field conditions toward T. granarium also in consideration of its relative low toxicity for humans.

The LT50 calculated for limonene was 86.83 hours while positive control using deltamethrin, used at the recommended dose of the manufacturer, was 5.20 hours after exposure. These data suggest that methyl salicylate can be exploited as a candidate for further tests in field conditions toward T. granarium also in consideration of its relative low toxicity for humans.","PeriodicalId":37777,"journal":{"name":"Journal of Entomological and Acarological Research","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140488864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Pentatomid bugs, commonly known as stink bugs, are typically herbivorous insects known for their piercing-sucking feeding habits on crops and wild plants. Among these stink bugs, Spermatodes variolosus (Walker, 1867) stands out as the smallest species, measuring 2.6-2.9 mm, and is also known to be phytophagous. In this study, we report the presence of seven species from six different genera of stink bugs in the rice fields of Cooch Behar, West Bengal. Notably, this research marks the first documented occurrence of Spermatodes variolosus (Walker, 1867) in the rice ecosystem of India, raising concerns about its potential pest status. Furthermore, this study includes taxonomic keys for the six genera identified.

The introduction of the invasive tick Rhipicephalus (Boophilus) microplus in Côte d'Ivoire has led to a change in the population of ticks of the genus Rhipicephalus (Boophilus). Thus, this study aims to characterize morphologically the tick species of the genus Rhipicephalus (B.) by geometric morphometry. It consisted of collecting all ticks from cattle in 74 farms in the Savanes District. The collected ticks were identified in the laboratory and, after identification, only non-gorged adult ticks of the genus Rhipicephalus (B.) were retained for morphometric characterisation. A total of 394 ticks were examined under a digital microscope, images were digitised using the online program XYOM and the data were analysed. This study revealed that males of each species have a smaller average size than females. It also showed a variation in mean size in all species except for the females of Rhipicephalus (B.) decoloratus and Rhipicephalus (B.) geigyi whose mean sizes did not differ. Geometric morphometry allowed the separation of Rhipicephalus (B.) annulatus males from other males. In females, Rhipicephalus (B.) geigyi and Rhipicephalus (B.) microplus were distinguished from each other and from other females.
在Côte d' ivivire引入入侵蜱(Boophilus) microplus导致了蜱属蜱(Boophilus)种群的变化。因此，本研究旨在利用几何形态计量学对鼻头蜱属蜱种进行形态学表征。它包括收集萨凡尼斯地区74个农场的所有牛蜱。收集到的蜱虫在实验室进行鉴定，鉴定后，仅保留鼻头蜱属(B.)的非大口成年蜱虫进行形态计量学表征。在数码显微镜下对394只蜱虫进行了检查，使用在线程序XYOM对图像进行了数字化处理，并对数据进行了分析。这项研究表明，每个物种的雄性都比雌性的平均体型小。除雌性脱色头和盖革头外，其余种属的平均大小均存在差异。几何形态测定法可以将环状棘头蝇雄性与其他雄性区分开来。在雌虫中，geigyi和microplus两种类型的母虫具有明显的差异性。
