ABSTRACT: The effectiveness of sanitation in preventing infestation of stored products by insects depends on the effect of food deprivation on the survival of those insects. The survival rate and progeny production of Lasioderma serricorne (Fabricius) (Coleoptera: Anobiidae) adults with different starvation periods was investigated at 27 ± 2 °C, 75 ± 5% relative humidity in the laboratory. Only 16.7 ± 3.3% of L. serricorne adults survived 18 d of starvation, and the number of adult progenies produced was reduced 90.9 ± 5.7% after 18 d of starvation. The results suggest that food deprivation for the duration of the study could effectively inhibit infestations by L. serricorne adults, which could assist in the design of effective stored product pest sanitation protocols.

ABSTRACT: The citrus longhorn beetle Anoplophora chinensis (Forster) (Coleoptera: Cerambycidae) is a destructive polyphagous species, which has been documented on broadleaved tree hosts from 40 genera. The antennal transcriptomes from male and female A. chinensis were constructed separately. We analyzed and annotated differentially expressed genes (DEGs) between male and female A. chinensis. The putative olfactory genes among the DEGs were identified. De novo assembly acquired 25,733 and 25,420 unigenes from male and female A. chinensis, respectively. After removing the redundant unigenes, 39,955 all-unigenes were produced. For male A. chinensis, the mean length of unigenes was 923 bp, and that was 881 bp in female. 24,359 (60.97%) of the all-unigenes were annotated in the nr database and the rest 15,596 (39.03%) unigenes could not find clear homology with recorded genes. A total of 4,672 genes were differentially expressed between males and females. Compared with males, 2,241 (47.97%) of the DEGs were up-regulated and 2,431 (52.03%) were down-regulated in females. We identified 31 differentially expressed olfactory genes between male and female A. chinensis, including 14 OBPs, 7 ORs, 4 GRs and 6 SNMPs. Results from the present study provided essential clues for explaining the behavior difference between male and female A. chinensis, and important information for developing bait traps for A. chinensis.

ABSTRACT: Quality assessments of commercially available biological control (BC) agents is important to ensure the success of a BC program. It is important that greenhouse producers assess if BC agents received from BC suppliers are alive and functional before releasing into greenhouse production systems. We conducted a preliminary study to determine the quality of shipments from two suppliers of the whitefly parasitoid, Eretmocerus eremicus Rose & Zolnerowich (Hymenoptera: Aphelinidae). Release cards containing parasitized pupae of the sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), were individually placed into 500 mL Mason jars and a 4 x 5 cm yellow sticky card was attached to the inner lids. We found differences between the two shipments received from the two suppliers. For the first shipment, supplier B had a higher mean number of adults captured on the yellow sticky cards than supplier A (Laboratory: 10.1 versus 4.2 and Distributor: 19.1 versus 5.9 adults, respectively). However, for the second shipment, supplier A had a higher mean number of adults captured on the yellow sticky cards than supplier B (Laboratory: 14.5 versus 8.1 and Distributor: 20.9 versus 8.0 adults, respectively). Our preliminary study shows that formulations (release cards) of BC agents and emergence of adults can vary depending on individual shipments from the supplier providing the BC agents. Therefore, greenhouse producers should develop protocols for quality assessments of purchased BC agents before releasing them into greenhouses to ensure they have the best chance of successfully regulating pest populations below damaging levels.
摘要：商业生物控制剂的质量评估对于确保生物控制计划的成功至关重要。重要的是，温室生产商应评估从BC供应商处收到的BC制剂在释放到温室生产系统中之前是否有效。我们进行了一项初步研究，以确定白蝇类寄生蜂的两个供应商Eretmoseurus eremicus Rose和Zolnerowich（膜翅目：Apelinidae）的发货质量。将含有红薯粉虱寄生蛹的释放卡，即烟粉虱（半翅目：Aleyrodidae），分别放入500 mL梅森罐中，并将一张4 x 5 cm的黄色粘性卡贴在内盖上。我们发现从两个供应商那里收到的两批货物有差异。在第一批货物中，供应商B在黄色粘卡上捕获的成年人平均人数高于供应商a（实验室：10.1人对4.2人，经销商：19.1人对5.9人）。然而，在第二批货物中，供应商A在黄色粘性卡上捕获的成年人平均人数高于供应商B（实验室：14.5人对8.1人，经销商：20.9人对8.0人）。我们的初步研究表明，BC制剂的配方（放行卡）和成人的出现可能因提供BC制剂的供应商的个别发货而异。因此，温室生产商应在将购买的BC药剂投放温室之前，制定对其进行质量评估的协议，以确保他们有最好的机会成功地将害虫种群控制在破坏水平以下。

ABSTRACT: We sequenced the complete mitochondrial genome of the fishfly species Acanthacorydalis fruhstorferi van der Weele (Megaloptera: Corydalidae). The genome, which was 15,286 bp in length, included a standard set of 13 protein-coding genes, 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and a putative A+T-rich region. The gene arrangement is identical to that of most common Megaloptera mitochondrial genomes. We analyzed the preferred codon usage of the protein-coding genes and predicted the secondary structures of all the RNA transcripts. In addition, a phylogenetic tree was constructed based on the sequences of the 13 protein-coding genes, and the results supported the current view of a close relationship between Megaloptera and Neuroptera. Our analyses suggest that complete mitochondrial genome sequences are a promising method to fully resolve the phylogenetic relationships within Megaloptera.
摘要/ ABSTRACT摘要:对棘翅目:棘翅科(Acanthacorydalis fruhstorferi van der Weele)蝇类进行了线粒体全基因组测序。该基因组全长15286 bp，包括13个蛋白质编码基因、22个转移RNA基因(tRNAs)、2个核糖体RNA基因(rnas)和一个假定的a + t富区。基因排列与大多数常见的大翅目线粒体基因组相同。我们分析了蛋白质编码基因的首选密码子使用，并预测了所有RNA转录本的二级结构。此外，基于13个蛋白编码基因的序列构建了系统发育树，结果支持了目前大翅目与神经翅目亲缘关系密切的观点。我们的分析表明，完整的线粒体基因组序列是一种很有希望的方法来全面解决大翅目动物的系统发育关系。

ABSTRACT: Stage-specific functional response of Coccinella septempunctata L. was evaluated under laboratory conditions to varying densities (10, 20, 40, 60, 80, 100, 120, 150 and 200) of Lipaphis erysimi (Kaltenbach)., Diuraphis noxia Kurdjumov. and Aphis nerii Fonscolombe. Logistic regression analysis of all life stages of C. septempunctata exhibited negative linear-coefficient (P1), confirming a curvilinear type II functional response against all the tested aphid species. The fourth instar of C. septempunctata, in comparison to other stages, exhibited the highest predation activity against D. noxia and A. nerii, with an attack rate (a) of 7.31 h-1, 5.79 h-1 and handling time (Th) of 0.0106 h, 0.0092 h, respectively. Under different densities of L. erysimi, adult females of C. septempunctata exhibited the highest predation activity with an a of 7.58 h-1, followed by the fourth instar with a of 7.31 h-1 and adult male 6.60 h-1 and Th of 0.0066 h, 0.0079 h and 0.0092 h, respectively. The attack rate and handling time estimated for different stages of C. septempunctata showed that the fourth instar of C. septempunctata had the highest attack rate, whereas handling time was variable. Adult females of C. septempunctata showed minimum handling time (0.00013 h) in most of the cases. Our results suggest that the fourth instar larvae and adult female of C. septempunctata are efficient predator for the biological control of L. erysimi, D. noxia and A. nerii. Further field-based studies are needed to confirm this hypothesis.

ABSTRACT: The cereal ground beetle,Zabrus tenebrioides Goeze (Coleoptera: Carabidae) is one of the most important pests of wheat in the southeastern region of Turkey. The larval stage lives in the soil and may cause severe damage to wheat crops. Damage by this pest is favored by a wheat monoculture or the use of untreated seeds. High soil moisture and moderate temperatures are favorable conditions for the development and attack of Z. tenebrioides larvae. The southeastern Anatolia region of Turkey is a hub of cereal production and Z. tenebrioides can attack the seedling stage of cereals in this region, resulting in heavy economic losses. This study was carried out during the years 2015 and 2017 to determine the biology of Z. tenebrioides in the southeastern Anatolia region. Surveys could not be carried out in 2016 as the climatic conditions were not suitable. Adults of this pest were monitored and data on the biology, aestivation and hibernation periods of Z. tenebrioides were recorded. Results indicated that aestivation (the last week of October) and hibernation (at the end of November and most of December) times, and the duration of egg, larval, pupal and adult stages are closely associated with soil temperature and moisture, followed by temperature and humidity of food and air. It was further observed that pest populations increased when the temperature was low and humidity was high, especially in the years receiving high precipitation during early spring and late autumn.

ABSTRACT: Pityopsis ruthii (Small) Small (Asteraceae: Asterales) is a federally endangered aster that only grows along short stretches of the Hiwassee and Ocoee Rivers in southeastern Tennessee, U.S.A. The species is self-incompatible and genetic drift and inbreeding depression have been reported. Multiple investigators have observed highly variable sexual reproductive capacity of P. ruthii. To better understand which insect species may be contributing roles as potential pollinators, floral visitation to P. ruthii was assessed at in situ and ex situ locations. Forty-seven insect species in 15 families and 3 orders were recovered across 2 years during more than 70 hours of observation and specimen collection. Megachile brevis Say (Megachilidae: Hymenoptera) carried the most pollen, yet just three specimens were collected, all from the ex situ location. In both years, Halictidae were common at the ex situ location and were infrequently collected at the in situ location. Apis mellifera L. (Apidae: Hymenoptera) and Bombus impatiens Cresson (Apidae: Hymenoptera) were commonly observed at in situ locations in both years, and in 2013 at the ex situ location. Toxomerus geminatus (Say) (Syrphidae: Diptera) was the most abundant floral visitor in both years but carried very little pollen. Floral visiting lepidopteran species carried no pollen. Greater numbers of P. ruthii inflorescences did not reliably influence Apoidea or Syrphidae floral visitor abundance in either the in situ or ex situ locations. Assessments of filled seeds revealed low germination rates. Hybridization between geographically disparate parent plants propagated from the distal ranges of Hiwassee River distribution yielded an average of 33 percent germination, validating evidence of inbreeding depression. Knowledge of P. ruthii floral visitors at in situ and ex situ locations can be employed to assist breeding efforts intended to increase genetic diversity through ongoing efforts in plant re-introduction and habitat management.
{"title":"Seed Production and Floral Visitors to Pityopsis ruthii (Asteraceae: Asterales), an Endangered Aster Native to the Southern Appalachians","authors":"P. A. Moore, W. Klingeman, P. Wadl, R.

The species is self-incompatible and genetic drift and inbreeding depression have been reported. Multiple investigators have observed highly variable sexual reproductive capacity of P. ruthii. To better understand which insect species may be contributing roles as potential pollinators, floral visitation to P. ruthii was assessed at in situ and ex situ locations. Forty-seven insect species in 15 families and 3 orders were recovered across 2 years during more than 70 hours of observation and specimen collection. Megachile brevis Say (Megachilidae: Hymenoptera) carried the most pollen, yet just three specimens were collected, all from the ex situ location. In both years, Halictidae were common at the ex situ location and were infrequently collected at the in situ location. Apis mellifera L. (Apidae: Hymenoptera) and Bombus impatiens Cresson (Apidae: Hymenoptera) were commonly observed at in situ locations in both years, and in 2013 at the ex situ location. Toxomerus geminatus (Say) (Syrphidae: Diptera) was the most abundant floral visitor in both years but carried very little pollen. Floral visiting lepidopteran species carried no pollen. Greater numbers of P. ruthii inflorescences did not reliably influence Apoidea or Syrphidae floral visitor abundance in either the in situ or ex situ locations. Assessments of filled seeds revealed low germination rates. Hybridization between geographically disparate parent plants propagated from the distal ranges of Hiwassee River distribution yielded an average of 33 percent germination, validating evidence of inbreeding depression. Knowledge of P. ruthii floral visitors at in situ and ex situ locations can be employed to assist breeding efforts intended to increase genetic diversity through ongoing efforts in plant re-introduction and habitat management.","PeriodicalId":17396,"journal":{"name":"Journal of the Kansas Entomological Society","volume":"93 1","pages":"327 - 348"},"PeriodicalIF":0.5,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48311092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
