It binds directly to its methoprene-tolerant receptor and recruits a heterodimer partner to form the JH–receptor complex that then activates a JH-inducible gene known as the Krüppel homolog 1 (Kr-h1). There is evidence that this gene is a downstream factor mediating both physiological and biochemical processes; however, the functional mechanism of Kr-h1 is largely unknown. Using the economically important rice (Oryza sativa L.) pest Chilo suppressalis (Walker) (Lepidoptera: Crambidae) as a model, we used a combination of RNA interference (RNAi), high-throughput RNA sequencing, and real-time quantitative polymerase chain reaction (RT-qPCR) to identify candidate transcription factor (TF) genes that are regulated by Kr-h1. RNAi knockdown of Krh1 identified the Zinc finger proteins, ZBTB, THAP, PAX, MYB, HSF, Homeobox, HMG, CSD, basic helix-loop-helix, STAT, RHD, and MBD families as regulated by Kr-h1. RT-qPCR confirmed the transcription levels of these putative TFs and indicated that knockdown of Kr-h1 can induce or suppress the expression of these proteins in C. suppressalis. These results provide the basic information required for in-depth research on the TFs regulated by Kr-h1 in C. suppressalis and other insects.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49001815","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}

Like other birds, bald eagles may be parasitized by a variety of ectoparasites including lice and mites (Price and Graham 1997, Chewing and Sucking Lice as Parasites of Mammals and Birds, USDA Tech. Bull. No. 1849, Washington, DC; Philips 2000, J. Raptor Res. 34:210– 231). Chewing lice, along with the other parasitic lice, were formerly placed in the insect Order Phthiraptera, but now have been placed within nonparasitic bark lice and book lice in the Order Psocodea (Durden 2019, Lice, Pg. 79–104, G.R. Mullen and L.A. Durden [eds.], Lice, Medical and Veterinary Entomology, 3ed, Elsevier, New York). Five genera of chewing lice, particularly those in the family Menoponidae have been reported previously from bald eagles (Price and Beer 1963, Can. Entomol. 95:731–763; Price et al. 2003, Illinois Natural History Survey Special Publ. No. 24), but records from Mississippi are rare or nonexistent. Here, we report four specimens of Colpocephalum sp. collected from two bald eagles nesting near the Mississippi Gulf Coast.

During the banding process, an estimated 15 lice were seen running across his fingers and arms; 4 were captured and placed in a vial of alcohol.

Herein, we characterized the relative expression patterns of six representative olfactory-related genes at different stages of M. alternatus parasitism and in different body regions of D. helophoroides neonates. The genes encoding chemosensory protein 2 (DhelCSP2), odorant receptor 2 (DhelOR2), and ionotropic receptor 2 (DhelIR2) were significantly upregulated before parasitization was initiated, whereas the genes encoding odorant binding protein 8 (DhelOBP8), gustatory receptor 5 (DhelGR5), and sensory neuron membrane protein 1 (DhelSNMP1) were significantly upregulated 4–5 d after initiation of parasitism. In D. helophoroides neonates, four genes (DhelOBP8, DhelCSP2, DhelOR2, and DhelIR2) were significantly upregulated in the head compared with the thoracoabdominal region, and one gene (DhelGR5) was significantly upregulated in the thoracoabdominal area compared with the head. Double-stranded RNAs (dsRNAs) targeting the six olfactory-related genes were synthesized and delivered to D. helophoroides neonates via immersion. After dsRNA treatment, the transcript levels of four olfactory-related genes (DhelOBP8, DhelCSP2, DhelOR2, and DhelSNMP1) were significantly reduced compared with that of the controls.

Both species have been deployed as biological control agents of water hyacinth, Pontederia (Eichhornia) crassipes (Martius) Solms-Laubach, in over 30 sites in South Africa. Our aim in this review was to gather and assimilate information on the chemical communication and chemical ecology of mirids, with an ultimate goal of enhancing the effectiveness of biological control agents of water hyacinth, particularly E. catarinensis and E. eichhorniae. Many hemipterans have highly developed metathoracic scent glands (MTGs), Brindley's glands, and secretory setae that store and emit chemicals that may act as allomones, kairomones, or pheromones. The preponderance of the available literature dealt with sex pheromones. Hexyl butyrate, (E)-4-oxo-2-hexenal, and (E)-2-hexenyl butyrate are reported to be sex pheromones in many mirids: for example, Adelphocoris fasciaticollis Reuter, Apolygus spinolae Meyer-Dür, Liocoris tripustulatus F., Lygocoris pabulinus L., several Lygus spp. (Lygus hesperus Knight, Lygus lineolaris Beauvois, Lygus elisus van Duzee, Lygus pratensis L., and Lygus rugulipennis Poppius), and Stenotus rubrovittatus Matsumura. Hexyl butyrate is the most prevalent sex pheromone in Miridae, while (E)-4-oxo-2-hexenal is the most prevalent sex pheromone in Heteroptera. Both pheromones co-occur in some species and exhibit many functionalities. The constancy of sex pheromones linked to behavioral patterns in Miridae suggest a punctuated equilibrium pattern of evolution (dating back to the Triassic), similar to morphological characters of many insects.","PeriodicalId":15765,"journal":{"name":"Journal of Entomological Science","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47863837","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}

The model showed that isothermality and the mean temperature of the driest quarter of the year were the most important environmental factors affecting the distribution of C. viridis and E. interruptus. Europe and southern China are the current primary habitat suitability areas for the two species. The high habitat suitability areas for C. viridis are also concentrated in these areas, whereas the high habitat suitability areas for E. interruptus are mainly found in western Europe. Under future climate change scenarios, the area of the two species habitat suitability areas increases, and the high habitat suitability areas for C. viridis decrease. However, the high habitat suitability areas for E. interruptus increase in 2041–2060 shared socioeconomic pathways 585 (ssp585) but decrease in 2041–2060 and 2061–2080 shared socioeconomic pathways 126 (ssp126).

Adult mortality 24 h after application of a 12% (w/v) concentration of the hexane extract was 73.3% for T. urticae and T. truncatus, whereas application of the methylene chloride extract caused 85.8% mortality of T. urticae and 85% mortality of T. truncatus. Lower concentrations (6–12%) of the methanol extract yielded low efficacy against T. urticae but exhibited high efficacy against T. truncatus (73.8–95.8%). In general, egg hatch was reduced <50% by 5 d following application of the extracts. Only the 6–12% concentration of the hexane extract caused higher levels of T. truncatus egg mortality ranging 55.4–68.7%. All extracts repelled adult mites over 64% from 5 to 72 h after exposure. However, the percentage of repellency showed no statistical differences in all treatments. Gas chromatography-mass spectrometry (GC-MS) analysis identified that the major chemical compounds in the hexane extract were DL-limonene (29.75%) and sabinene (9.76%), whereas limonene (40.70%) and sabinene (16.60%) were the principal constituents of the methylene chloride extract.

In this study, we evaluated the efficacy of insecticides with different modes of action in diverse locations under different levels of S. frugiperda larval infestation. The insecticides evaluated decreased larval density per plant to levels below the recommended economic threshold (ET) of 2.0 larvae per 10 plants (0.2/plant), resulting in decreased levels of damage to the plant whorl. When applied at infestation levels below the ET, larval numbers remained below the ET for at least 7–14 d after application. In contrast, when applied with infestation levels above the recommended ET, the performance of some insecticides in terms of effectively reducing larval density decreased. We, however, found that Coragen® (chlorantraniliprole; FMC Agroquímica de México), Clavis® (thiodicarb + triflumuron; Bayer de México), and Pleo® 50 EC (pyridalyl; Valent de México) can be used under these conditions to provide adequate protection up to 21 d after application.
