Winter fruit contribution to the performance of the invasive fruit fly Drosophila suzukii under different thermal regimes

open access: yesInsect Science, EarlyView.
Highlights: The contribution of winter and early spring‐available fruit (Aucuba japonica, Elaeagnus ×submacrophylla, and Viscum album) to the performance of D. suzukii depended on their P:C ratio and biophysical properties Even though D. suzukii performance was the lowest in A.

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

open access: yesInsect 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 ...

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

External Morphology of Immatures of Mischocyttarus nomurae Richards (Hymenoptera, Vespidae) during the Post-embryonic Development

open access: yesSociobiology, 2016
The work on this paper aimed to perform the description of the immatures and determine the number of larval instars in the post-embryonic development of Mischocyttarus nomurae Richards, a social wasp which the only works performed were the description of

The transformer gene controls sexual development in Drosophila suzukii

open access: yesInsect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

LARVAL SPECIFIC CHARACTERS AND INSTARS OF ENGLISH BOMBIDAE

open access: yesProceedings of the Royal Entomological Society of London. Series A, General Entomology, 1949
FOURTH instar larval characters of American BOMBIDAE (BREMIDAE) were described by Ritcher (1933) for nine species of Bombus (Bremus) and one species of Psithyrus. These two genera were separated on the shape of the mandibles. An attempt was made to separate the species of Bombus (Bremus) on the characters of the mesothoracical spiracles and the pleural
