Defensive responses by a social caterpillar are tailored to different predators and change with larval instar and group size [PDF]

, 2011
Gregariousness in animals is widely accepted as a behavioral adaptation for protection from predation. However, predation risk and the effectiveness of a prey’s defense can be a function of several other factors, including predator species and prey size ...

Innate behaviours shape generalist herbivore host choice and feeding patterns independent of plant defences

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant–herbivore interactions are typically examined through plant defence and herbivore performance, yet individual herbivore behavioural mechanisms underlying these interactions are rarely considered alongside plant traits.

Growth and development in a lepidopteran with variable instar number, Pseudocoremia suavis (Geometridae), under standard rearing conditions and when parasitised by Meteorus pulchricornis (Hymenoptera: Braconidae)

European Journal of Entomology, 2014
Though extra instars are often associated with poor conditions and thought to be a compensation for a low growth rate, the reasons why they are necessary, and for variable instar number existing under standard rearing conditions, are not yet clear.

Field validation of blow fly age estimation methods for determining time of placement of human remains in Tennessee, USA

Journal of Forensic Sciences, EarlyView.
Abstract Forensic entomology currently represents one of the best approaches for estimating the minimum postmortem interval (PMIMIN) in medicolegal death investigations given certain parameters and assumptions are met. However, validation of standard estimation methods used in this field are few and far between.

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Pho and Ph, H3K27me3 and Cg ChIP-seq data in Drosophila third instar larval brains and discs

, 2016
Genome-wide binding profile of PcG proteins- Ph, H3K27me3 and Cg in Drosophila third instar larval brains and disks, in duplicate, using Illumina HiSeq 2500. The sequence reads that passed quality filters were analyzed.

Novel equation for estimating corpus allatum activities during the last larval instar of the eri silkworm

, 1992
An equational model to evaluate the juvenile hormone (JH) level in the haemolymph of the last larval instar of the Eri silkworm Philosamia ricini has been designed.

Patterns of gene expression from single-cell RNA-Seq of the third instar larval testes

, 2020
Patterns of gene expression from single-cell RNA-Seq of the third instar larval testes. For each gene we plot the Uniform Manifold Approximation and Projection (UMAP) colored by Z-score value (-3, 3).

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.
