Identification of a self-regulatory pheromone system that controls nymph aggregation behavior of rice spittlebug Callitettix versicolor

open access: yesFrontiers in Zoology, 2015
BackgroundNymphs of many spittlebug species are known to aggregate in one spittle mass, a behavior which greatly benefits the survival of the developing nymphs.

Differences in within‐plant oviposition preferences and immature survival between Orius predators and the importance of spatial availability of prey

open access: yesInsect Science, EarlyView.
Orius predators oviposit endophytically, and plant characteristics play an important role in their oviposition choices. In this study, we show that oviposition preferences differ between species, and that these differences may correlate with juvenile performance.

Microinjection‐enabled gene silencing in first instar larvae of western flower thrips, Frankliniella occidentalis, reveals vital genes for larval survival

open access: yesInsect Science, EarlyView.
This study introduces a microinjection technique to deliver dsRNA into the hemolymph of first instar larval thrips (L1s) via the foreleg coxa, enhancing survival rates by minimizing internal tissue damage. Significant knockdown of V‐ATPase‐B, CYP3653A2, and ApoLp‐II/I was achieved, with silencing of CYP3653A2 or ApoLp‐II/I increasing larval mortality ...

Insights on the phenology of the Asian longhorned tick (Haemaphysalis longicornis) using stored lipids

open access: yesInsect Science, EarlyView.
Lipid analysis of field‐collected ticks unveiled a complex population structure and supports the potential for several stages to overwinter. Abstract The seasonality of Haemaphysalis longicornis in the United States comprises overlapping life stages in the spring and summer.

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

open access: yesInsect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.
