Abstract:
... Natal rearing experience of animals may affect their behaviors, such as habitat selection and oviposition decision. As part of the overall fitness of insect parasitoids, successful host discrimination (distinguishing parasitized hosts from unparasitized hosts) is of paramount importance. In this study we examined whether and how parasitoids’ natal rearing experience would affect their host discrim ...

Abstract:
... As a core member of the Hippo signaling pathway, Hpo plays a critical role in regulating growth and development. Previous studies reported that loss of function of Hpo results in increased proliferation, reduced apoptosis and induction of tissue overgrowth in Drosophila. In this study, we used CRISPR/Cas9 (Clustered Regularly Interspaced Short Palindromic Repeats/Cas9) to study Hpo gene (BmHpo) fu ...

Abstract:
... Malpighian tubules (MTs) are usually considered the key excretory and osmoregulatory organs of insects. However, increasing evidence has suggested that MTs perform many more functions than just osmoregulation. Until now, the molecular and physiological functions of MTs in the cotton bollworm (Helicoverpa armigera), a very important agricultural pest, are largely unknown. In this study, the transcr ...

Abstract:
... Tyrosine hydroxylase (TH) is involved in insect melanin and the catecholamine biosynthesis pathway. TH as an enzyme catalyzing the conversion of tyrosine to 3,4‐dihydroxyphenylalanine is the first step reaction in the pathway. Although TH has been proven to affect the pigmentation of the epidermis and development in many insects, there is no report about physiological function of the TH gene in Ag ...

Abstract:
... The stylet penetration behavior of aphids when feeding on plants is associated with virus acquisition and inoculation. Aphidius gifuensis (Ashmead) is a primary endoparasitoid of Myzus persicae (Sulzer) which is the most efficient vector of plant viruses. Information about the effects of parasitoid on aphid and virus transmission can provide an essential foundation for designing effective biologic ...

Abstract:
... Among tephritid fruit flies, hybridization has been found to produce local adaptation and speciation, and in the case of pest species, induce behavioral and ecological alterations that can adversely impact efficient pest management. The fraterculus species group within Anastrepha (Diptera: Tephritidae), is a rapidly radiating aggregate, which includes cryptic species complexes, numerous sister spe ...

Abstract:
... Global climate change and acquired resistance to insecticides are threats to world food security. Drosophila suzukii, a devastating invasive pest in many parts of the world, causes substantial economic losses to fruit production industries, forcing farmers to apply broad‐spectrum insecticides frequently. This could lead to the development of insecticide resistance. We determined the Lethal Concent ...

Cytochrome P450 CYP6B7 has been reported to be involved in pyrethroid insecticide resistance in Helicoverpa armigera, and its transcription level was induced by some inducers. Currently, the regulatory mechanism of the induced expression of CYP6B ...

Abstract:
... Organisms often live in unpredictable environments and have to adopt life history strategies that optimize their fitness under these conditions. According to bet‐hedging theory, individuals can reduce variation in fitness outcomes by investing in different strategies at the same time. For arthropods, facultative summer diapause enables survival during dry and hot periods of the year, and can be tr ...

Abstract:
... The diamondback moth, Plutella xylostella (L.), uses sulfatases (SULF) to counteract the glucosinolate–myrosinase defensive system that cruciferous plants have evolved to deter insect feeding. Sulfatase activity is regulated by post‐translational modification of a cysteine residue by sulfatase modifying factor 1 (SUMF1). We identified 12 SULF genes (PxylSulfs) and two SUMF1 genes (PxylSumf1s) in t ...

Gram‐negative binding protein 3 (GNBP3) has a strong affinity for the fungal cell wall component, β‐1,3‐glucan, which can activate the prophenoloxidase (proPO) cascade and induce the Toll signaling pathway. Myeloid differentiation factor 88 (MyD88) is an intracellular adaptor protein involved in th ...
