Parasitoid cues modulate Drosophila germline development and stem cell proliferation

Cell Reports
Summary: Environmental factors influence an organism’s reproductive ability by regulating germline development and physiology. While the reproductive adaptations in response to extrinsic stress cues offer fitness and survival advantages to individuals ...

Factors Influencing Length and Volume of Cells Provisioned by Two \u3ci\u3ePassaloecus\u3c/i\u3e Species (Hymemoptera: Sphecidae) [PDF]

, 2017
Length of cells provisioned by Passaloecus areolatus and Passaloecus cuspidatus decreased as bore diameter increased, but volume of provisioned cells increased with increasing bore diameter.

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

Pest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

Effect of the nutritional quality of primary food on the development, sex ratio, and size of a parasitoid in a quadri-trophic food web

European Journal of Entomology, 2023
This study explores the effect of nutritional composition on the fitness of consumers in a quadri-trophic food web. Specifically, we studied how enrichment of the food of fruit flies Drosophila melanogaster (Meigen, 1830) transfers to the spider ...

Entomological and functional role of floral strips in an organic apple orchard: Hymenopteran parasitoids as a case study [PDF]

, 2012
Habitat manipulation techniques improve the availability of resources required by natural enemies to increase their effectiveness. This study focused on the effects of floral strips on Hymenopteran parasitoid presence.

Effects of timed LED regimes on tomato plant traits, performance of two‐spotted spider mites, and predatory mites (Phytoseiulus persimilis)

Pest Management Science, Volume 81, Issue 4, Page 2300-2311, April 2025.
Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...

Effect of vermicompost on functional response of the parasitoid wasp Aphidius colemani (Hym., Braconidae) to the melon aphid, Aphis gossypii (Hem., Aphididae) [PDF]

نامه انجمن حشره‌شناسی ایران, 2017
Changing of host plant quality via agricultural practices such as application of fertilizer may influence the behavioral traits of natural enemies. In this study, the effect of improving cucumber plants with different vermicompost: soil ratios (0:100 ...

Metabolomics of aging assessed in individual parasitoid wasps [PDF]

Scientific Reports, 2016
AbstractMetabolomics studies of low-biomass organisms, such as small insects, have previously relied on the pooling of biological samples to overcome detection limits, particularly using NMR. We show that the differentiation of metabolite profiles of individual 1 mg parasitoid wasps of different ages is possible when using a modified sample preparation

Lack of phenotypic and evolutionary cross-resistance against parasitoids and pathogens in Drosophila melanogaster [PDF]

, 2012
BackgroundWhen organisms are attacked by multiple natural enemies, the evolution of a resistance mechanism to one natural enemy will be influenced by the degree of cross-resistance to another natural enemy.

Developing together: The elementome and biogeochemical niche of the mutualistic occupants of a fig microcosm

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In brood‐site pollination mutualisms, where flowers provide nutrition and shelter to pollinator offspring in exchange for pollination, resource allocation to inflorescences is directly related to plant and pollinator fitness.
