Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Fourlined Plant Bug (Hemiptera: Miridae), a Reappraisal: Life History, Host Plants, and Plant Response to Feeding [PDF]

open access: yes, 2017
Phenology of the fourlined plant bug, Poecilocapsus lineatus, is presented for southcen- tral Pennsylvania; life history and habits are re-examined. Although breeding was previously thought to occur only on woody plants, we found that nymphs develop on ...

L\'evy flights and self-similar exploratory behaviour of termite workers: beyond model fitting [PDF]

open access: yes, 2014
Animal movements have been related to optimal foraging strategies where self-similar trajectories are central. Most of the experimental studies done so far have focused mainly on fitting statistical models to data in order to test for movement patterns ...

Living cockroach genus Anaplecta discovered in Chiapas amber (Blattaria: Ectobiidae: Anaplecta vega sp.n.) [PDF]

open access: yesPeerJ, 2019
Cenozoic cockroaches are recent and with two indigenous exceptions, based on their fragmentary preservation state, they cannot be discriminated formally from representatives of living genera. Anaplecta vega sp.n.

A morphometric and molecular study of the genus Pseudopodisma (Orthoptera: Acrididae) [PDF]

open access: yes, 2017
The specific status of three described taxa belonging to the genus Pseudopodisma (P. fieberi, P. transilvanica, P. nagyi) is based on a single character, because the original descriptions separate the species solely on the basis of genital structure of ...

Substrate Preference of Black Soldier Fly Larvae Is Influenced by Rearing History

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
BSF larvae were reared under six different conditions: low, medium, or high larval density and on low, medium, and high‐water feeds to investigate feed choice behaviour. Larvae reared under all six conditions preferred substrate colonised by conspecifics. Low‐water feed caused slower larval growth and development.
