Isolating the role of the matrix at patch and landscape scales

open access: yesJournal of Animal Ecology, EarlyView.
This is the first experimental test of the spatial scales of matrix effects. Both patch‐scale and landscape‐scale matrix influence populations through a cross‐scale interaction altering survival, reproduction, and movement. Conservation in fragmentated landscapes should consider the matrix context of patches while focusing on local matrix due to its ...

Biological invasion by the cycad‐specific scale pest Aulacaspis yasumatsui (Diaspididae) into Cycas revoluta (Cycadaceae) populations on Amami‐Oshima and Okinawa‐jima, Japan

open access: yesPlant Species Biology, EarlyView.
This article details the invasion of cycad aulacaspis scale into the islands of Okinawa‐Jima and Amami‐Oshima. Several recommendations are proposed in this article by members of the IUCN cycad specialist group and experts in the biological control of this scale insect.

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

Portable Fourier‐transform infrared spectroscopy and machine learning for sex determination in third instar Chrysomya rufifacies larvae

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Forensic entomology is crucial in medicolegal investigations, utilizing insects—primarily flies—to estimate a supplemental post‐mortem interval based on their development at the (death) scene. This estimation can be influenced by extrinsic factors like temperature and humidity, as well as intrinsic factors such as species and sex.

Foraging by predatory ants: A review

open access: yesInsect Science, EarlyView.
This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

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 ...
