ABSTRACT: Small swarms of male Leseha vespa Smith & Nishida, 2019 flew during the morning hours searching for the much less abundant females on the upper surfaces of protruding leaves of various plant species at a site where a large population of the host fern Phlebodium pseudoaureum had been recently decimated (probably by L. vespa larvae). Males showed no sign of aggressive behavior toward other males, and only poor abilities to locate females resting on leaves. Although >100 male-female interactions were observed, they seldom led to copulation, as females were generally unreceptive. The males probably used visual cues to choose leaves, but the short-range cues that they used to encounter females there were not clear. Individually marked males returned to the same site for up to 11 days.
摘要/ ABSTRACT摘要:在一个寄主蕨类植物假金丝兰(Phlebodium pseudoaureum)最近遭到大量屠杀(可能是被L. vespa幼虫)的地点，一群雄性Leseha vespa Smith & Nishida 2019在早晨的几个小时里，在各种植物突出的叶子的上表面上寻找数量少得多的雌性。雄性没有表现出对其他雄性的攻击行为，只有很差的能力来定位躺在树叶上的雌性。虽然观察到100多只雄性和雌性的互动，但它们很少导致交配，因为雌性通常不接受。雄性可能使用视觉线索来选择树叶，但它们用来在那里遇到雌性的近距离线索并不清楚。单独标记的雄性会回到同一个地点长达11天。

ABSTRACT: The aim of this study was to identify the nest materials, some physical characteristics and the essential composition of the nest of Vespa crabro germana Christ, 1791. Nest surfaces were observed with a stereomicroscope and a scanning electron microscope. In the inner surface of the V. c. germana nest, the medium thicknesses of the fibers in the envelope and comb varied between 5.30 and 11.90 µm with an average of 9.07 µm. In the outer surface of the nest, the medium thicknesses of the fibers in the envelope and comb were between 4.46 and 11.40 µm with an average of 7.68 µm. The nitrogen and protein concentration of the nest was 0.22 and 1.40%, respectively. The percentages of the fibers, saliva, oil and the water absorption capacity were calculated as 70-75, 25-30, 16-20 and 120-150, respectively. The amount of the elements nickel and copper in the nest was found to be 0.6 and 1.2 ppm, respectively. The major components of the nest were plant fibers, saliva and oil. Consequently, we have found that the ratios and the amounts of physical characteristics, the element composition and the fibers in the envelope and comb of the nest changed with environmental conditions.

ABSTRACT: We investigated gene expression related to endoplasmic reticulum (ER) stress, apoptosis, and autophagy to understand how Gryllus bimaculatus (two-spotted field cricket) overcomes starvation stress. Male adults were used in starvation experiments. Expression levels of genes related to ER stress, apoptosis, and autophagy were investigated for each tissue after starvation stress (consisting of 1, 3, and 6 days of starvation, and 1 and 2 days of refeeding after 6 days of starvation) by reverse-transcription PCR. Furthermore, Malpighian tubules were stained with LysoTracker Red to observe autophagy. Starvation significantly upregulated gene expression of ER chaperones in the Malpighian tubules of G. bimaculatus. Gene expression levels of BiP, ERap2, and SERCA were upregulated up to 2.5-fold, ATF6 was upregulated up to 2-fold, and PDI and Derl2 were upregulated up to 1.5-fold in the starvation group compared to controls. Although autophagy was induced by starvation, apoptosis was not. Notably, gene expression of ATG9 was upregulated up to 15-fold in the Malpighian tubules of G. bimaculatus, which is the highest among the autophagy-related genes. These results suggest that ER stress-induced autophagy appears to be acutely involved in the mechanism by which insects overcome starvation stress.

ABSTRACT: Mirid bugs (Hemiptera: Miridae) are important pests of Eucalyptus (Myrtaceae) trees in Indonesia. Young Eucalyptus plantations are mainly affected by Helopeltis spp. Damage by Helopeltis resulted in die-back of young shoots, curling, deformation and drying usually, irrespective of the clones. In North Sumatra, damage in Eucalyptus is associated to Helopeltis bradyi Waterhouse despite the presence of H. theivora Waterhouse in the region. Important alternate host plants recorded as reservoirs of H. bradyi in vicinity to Eucalyptus plantations were Persea sp. (Lauraceae), Coffea sp. (Rubiaceae), Psidium guajava (Myrtaceae), Ludwigia sp. (Onagraceae), Clidemia hirta (Melastomataceae) and Theobroma cacao (Malvaceae). Leiophron sp. (Hymenoptera: Braconidae) was reported as an important parasitoid with parasitism of 41.86% on the H. bradyi nymphs and 17.07% on adults. Helopeltis theivora was recorded as the only species affecting Eucalyptus plantations in Riau Province, so far no other Helopeltis sp. has been identified in Riau. Ragwelellus festivus Miller and Ragwelellus sp. were reported for the first time damaging Eucalyptus trees in North Sumatra, Riau Province and East Kalimantan regions of Indonesia. Arthriticus eugeniae Bergroth was also reported for the first time damaging matured Eucalyptus trees along with Ragwelellus in North Sumatra and Riau Provinces.

ABSTRACT: In the coastal mid-Atlantic region of the USA, landscapes are a mosaic of upland habitats (woodland, grassland, old fields and farmland) and low-lying coastal salt marsh. Flooding and salinization of coastal areas due to sea-level rise result in the conversion of upland habitats to salt marsh, and change the relative proportion of habitat types surrounding coastal farmland. This has the potential to influence population sizes of organisms living in this area and could alter the ecosystem services, such as pollination, that these habitats provide. To examine the potential outcome of these habitat conversions, we used blue vane traps at 14 sites along the Eastern Shore of Virginia (USA) to compare the bee communities of salt marsh, old fields and agricultural fields. Although there was no difference among habitat types for total bee abundance per site, we found that the coastal marsh is depauperate in bee species relative to old fields and agricultural fields, and that the bee species using the marsh habitat tend to be specialists of plant families that are common in the marsh (Asteraceae and Malvaceae) but are relatively uncommon in local agriculture. Thus, the transition of upland areas to marsh not only has the potential to impact agricultural productivity directly through salt water intrusion, ultimately it may also reduce the species richness of native bees available to provide pollination services to coastal agriculture.

ABSTRACT: A species of large carpenter bee, Xylocopa virginica virginica (Linnaeus, 1771), is reported from Montana and Idaho, USA for the first time. This new Montana distribution record adds to a growing list of bee species found in the state and contributes to an ongoing inventory of the bees of Montana. The Montana collection likely does not represent an established population but a transient accidental introduction resulting from human transportation since Montana is considerably geographically separated from the published distribution of this species and no additional adults have been found. The Idaho collections may represent an established local population as there are several specimens and online records in or near Boise on multiple dates and years. An online record of a specimen of X. californica arizonensis Cresson, 1879 from Montana proved to be erroneous. The distribution of X. virginica is reviewed and the economic, social, and ecological implications of the occurrence or establishment of this species in Montana and Idaho are discussed.

ABSTRACT: The peach fruit fly, Bactrocera zonata S. is a species that can cause important economic losses to various fruit species, with more than 50 host plants. In this study, repellent and oviposition deterrent effects of methanol (Mx), ethanol (Ex) and distilled water (Dx) extracts of moringa bark and leaves, cinnamon, peppermint and ginger were evaluated at different concentrations (10, 20 and 30%) against B. zonata adults. The experiment was carried out by using free choice test. Among all extracts, peppermint (Pm) extracts (Pm-Mx, Pm-Ex and Pm-Dx) delivered important repellent activity at the maximum dosage (30%), i.e. 0.50, 0.75 and 0.50 mean number of adults, respectively; while, the minimum repellent activity was observed in moringa bark of all three extracts. Correspondingly, all extracts have oviposition deterrent effect but Peppermint (Pm) extracts (Pm-Mx, Pm-Ex and Pm-Dx), deliver the best effect. The present investigation revealed that bio-active extracts can be used as alternative cost-effective, safe, and environment-friendly insecticides for the effective management of B. zonata in order to reduce the ecological hazards caused by traditional chemical pesticides.

ABSTRACT: Blister beetles (Coleoptera: Meloidae) have a long history in human culture, are detrimental to human health, and considered an agricultural pest. However, little is known about the ecology of many of these beetle species in natural systems. The black blister beetle, Epicauta pensylvanica (Degeer), is a common fall species that regularly feeds on goldenrod (Solidago spp.) flowers. Previous ecological research used mass releases to explore movement patterns and habitat use. For a more natural investigation, a marking study was conducted to quantify the population size, movement patterns, and habitat use in a restored tallgrass prairie and adjacent degraded grassland. We uniquely marked a total of 914 individuals, recapturing 22.2% over 16 surveys (16 August to 11 October 2018). A maximum daily count of 286 individuals was recorded on 11 September, corresponding to a population size estimate of 2,011 (1,258– 4,139 95% CI). Several times, adult numbers increased one to two days following rain events, and ultimately dropped substantially following mowing of the degraded grassland. Beetles were capable of moving throughout the study site based on one individual traveling at least 599 m over the course of the study. However, most detected movements were short and there was no preference in movement directionality, suggesting that beetles would most often move to adjacent flowering goldenrod patches. Despite the lack of directionality, the restored tallgrass prairie portion of the study site retained significantly more beetles than the degraded grassland. While further describing the ecology of the black blister beetle, this study also supports the effectiveness of the habitat restoration efforts.

While further describing the ecology of the black blister beetle, this study also supports the effectiveness of the habitat restoration efforts.","PeriodicalId":17396,"journal":{"name":"Journal of the Kansas Entomological Society","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2020-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42607087","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}
