Calcineurin-Modulated Antimicrobial Peptide Expression Is Required for the Development of Helicoverpa armigera

Frontiers in Physiology, 2019
Helicoverpa armigera is a universal pest around the world that has been extensively used as a model organism for agricultural pests. Calcineurin (CAN) is an important Ca2+-dependent phosphatase that is participated in various biological pathways.

Muffled olfactory and sensory cues from the reproductive stage soybean selectively reduce oviposition of a major polyphagous herbivore, fall armyworm (Spodoptera frugiperda)

Pest Management Science, EarlyView.
Fall armyworm (FAW) preferred ovipositing on vegetative‐stage soybeans. While ‘mother knows best’ may not apply in soybean‐FAW system, muffled cues in the reproductive stage could positively influence host success. Abstract BACKGROUND While the mother knows best/preference performance hypothesis has been well tested in natural ecosystems, how these ...

Diet-delivered RNAi in Helicoverpa armigera – Progresses and challenges [PDF]

Journal of Insect Physiology, 2016
Helicoverpa armigera (the cotton bollworm) is a significant agricultural pest endemic to Afro-Eurasia and Oceania. Gene suppression via RNA interference (RNAi) presents a potential avenue for management of the pest, which is highly resistant to traditional insecticide sprays.

Exploring the impact of a chemical disinfectant and an antiviral drug for RNA virus management in the Mediterranean fruit fly mass‐rearing

Insect Science, EarlyView.
Abstract The Mediterranean fruit fly is an agricultural pest of a wide variety of fruit crops. An effective method to counteract them in the field is through the application of the sterile insect technique, which requires the mass‐production of sterile males.

Role of mitochondrial complex I genes in host plant expansion of Bactrocera tau (Tephritidae: Diptera) by CRISPR/Cas9 system

Insect Science, EarlyView.
The role of 3 mitochondrial complex I gene in host expansion of Bactrocera tau was verified by CRISPR/Cas9 gene editing system. A stable homogenous strain (Btndufa7‐/‐) of B.tau was established after silencing Ndufa7. The reduced size of larvae and pupae of Ndufa7 knockout strain was first found.Then different levels of fitness and relative expression ...

Insights on the nutritional ecology of a nocturnal pollinating insect

Insect Science, EarlyView.
Nutritional ecology examines the environmental effects on nutritional needs, food intake and foraging behaviors, and the use of nutrients ingested by animals. Among insects, Lepidoptera are often considered opportunistic foragers that visit a wide variety of available flowers, although with some preferences.
