Expression profile of miR-92a and miR-92b in third Instar larval brain.

open access: yes, 2015
(A) Northern blot analysis of total RNA isolated from staged wild type flies (lanes 1–13) and miR-92–/– mutant third instar larvae (lane 14). RNA was probed for miR-92a (top), miR-92b (middle), and U6 (bottom). (B) In situ analysis of mir-92a in the wild

Agricultural Fungicide Mancozeb in Leaf Litter Enhances Survival and Growth of Aedes aegypti (Diptera: Culicidae)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Mancozeb is one of the most widely used agricultural fungicides, exhibiting strong efficacy against a broad spectrum of phytopathogenic fungi. However, its widespread application comes at the cost of environmental contamination. Here, we show the effects of Inga vera leaf litter contamination with Mancozeb on life‐history traits of Aedes ...

Attraction and oviposition preferences of Phlebotomus papatasi (Diptera: Psychodidae), vector of Old-World cutaneous leishmaniasis, to larval rearing media

open access: yesParasites & Vectors, 2015
Background As part of a project aimed at developing oviposition attractants for the control and surveillance of Phlebotomus papatasi (a vector of Old-World cutaneous leishmaniasis), we tested the hypothesis that gravid sand flies are attracted to ...

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

open access: yes, 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.

High nitrogen loading impacts the temperature‐size rule and heat tolerance in a nettle‐feeding butterfly

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host‐plant quality and ambient temperature are key environmental drivers of herbivorous insect performance, affecting growth, development, and survival. While temperature accelerates physiological processes in ectothermic insects, nutrient limitation in host plants can ...

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)

open access: yesEuropean 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.

Age-related cannibalism and horizontal transmission of a nuclear polyhedrosis virus in larval Spodoptera frugiperda

open access: yes, 1999
1. Experiments were carried out to investigate the incidence of cannibalism throughout the larval development of the noctuid moth Spodoptera frugiperda, and to examine the risk of infection from consuming conspecifics infected with a nuclear polyhedrosis

First year growth in the lithodids Lithodes santolla and Paralomis granulosa reared at different temperatures [PDF]

open access: yes, 2005
The southern king crab, Lithodes santolla Molina, and stone crab, Paralomis granulosa Jacquinot, inhabit the cold-temperate waters of southernmost South America (southern Chile and Argentina), where stocks of both species are endangered by overfishing ...

Plasticity in parental care: Interspecific competitor cues shape biparental cooperation in a burying beetle

open access: yesJournal of Animal Ecology, EarlyView.
Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Pho and Ph, H3K27me3 and Engrailed ChIP-seq data in Drosophila third instar larval brains and disks

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