Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

Insect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

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.

High quality genomic resources for stored product insects

Julius-Kühn-Archiv, 2018
The expansion of genomic resources for stored product insects has largely been hampered by cost, time required for inbreeding, and technical issues that can arise during genome assembly from pooling multiple individuals together for DNA isolation and ...

Competitive Interactions Between Generalist Predators and Their Effects on Shared and Non‐Shared Pests in a Greenhouse Crop

Entomologia Experimentalis et Applicata, EarlyView.
Orius laevigatus engages in unidirectional intraguild predation on Transeius montdorensis. Despite this, both predators coexisted and suppressed the shared thrips prey. Aphids, a non‐shared prey, were effectively controlled by O. laevigatus even when its population was limited due to intraguild predation. T.

Development and Reproduction of Nesidiocoris tenuis Reuter (Heteroptera: Miridae): The Effect of Temperature, Origin and Food

Entomologia Experimentalis et Applicata, EarlyView.
Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.

The mitochondrial genome of Ephestia elutella (Insecta: Lepidoptera: Pyralidae)

Mitochondrial DNA. Part B. Resources, 2018
In this study, the complete mitochondrial genome of the tobacco moth Ephestia elutella was sequenced and analyzed. The mitochondrial genome is 15345 bp long and contains 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region ...

Oviposition preference and olfactory response of Diaphania indica (Lepidoptera: Pyralidae) to volatiles of uninfested and infested cucurbitaceous host plants

European Journal of Entomology, 2019
The cucumber moth, Diaphania indica (Saunders) (Lepidoptera: Pyralidae), is a major pest of cucurbitaceous plants. The oviposition preference and olfactory response of larvae, mated and unmated male and female adults to volatiles emanating from ...

A New Experimental Setup to Study the Olfactory Behaviour of Trichogramma Egg Parasitoids

Entomologia Experimentalis et Applicata, EarlyView.
We developed an experimental setup to assess odor‐induced egg‐laying behavior in tiny egg‐parasitoid wasps. This Y‐shaped olfactometer, coupled with an AI‐based image‐recognition model, automatically quantifies egg parasitism by Trichogramma wasps. Olfactory‐driven egg‐laying preferences were analyzed using Bayesian inference.

Impact of Host and Food Availability on Life‐History Traits in Six Egg Parasitoid Species of the Genus Trichogramma

Entomologia Experimentalis et Applicata, EarlyView.
In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Comparative Toxicity of Bordeaux Mixture by Ingestion and Cuticular Contact Under Climate Change Conditions on Trichogramma cordubensis

Entomologia Experimentalis et Applicata, EarlyView.
In the face of environmental contamination to copper, mainly resulting from frequent copper‐based fungicide applications, it is crucial to understand the side effects of these pesticides on non‐target organisms to improve pest management. Trichogramma cordubensis, used as a biological control agent against grape berry moths in vineyards, shows strongly
