Molecular analysis of the gut contents of Harmonia axyridis (Coleoptera: Coccinellidae) as a method for detecting intra-guild predation by this species on aphidophagous predators other than coccinellids

European Journal of Entomology, 2013
Several studies have demonstrated that the invasive ladybird Harmonia axyridis is a strong intra-guild predator of native species of ladybird. Laboratory studies have shown that H.

Managed pollination is a much better way of increasing productivity and essential oil content of dill seeds crop

Scientific Reports, 2022
Dill seeds (Anethum graveolens L.) is the most valuable medicinal seed spice crop of Apiaceae. It bears small yellow flowers in the form of umbels. Being a cross-pollinated crop, floral visitors play vital role in pollination and seed sets.

Coevolution and Functional Effects of Endosymbiotic Rickettsia in Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae) Across China

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Two distinct lineages of L. invasa and the dominant endosymbiont, Rickettsia, was identified, followed by an analysis of its infection density across various developmental stages and tissues of L. invasa. Furthermore, two distinct strains of the Rickettsia endosymbiont were detected, and the phylogenetic relationships between these strains and their L.

THE IMPACT OF FOOD RESOURCES ON FITNESS OF EPISYRPHUS BALTEATUS

International Journal of Advance in Scientific Research and Engineering, 2018
Syrphids effectiveness as predators of aphids depends on the supply and quality of pollen and nectar. Pollen is required for reproduction and nectar for survival. Most investigations have focused on the interaction between prey and the predator while overlooking the importance of food foraging and supply during the different physiological phases. It is

Plant identity determines pollinator, natural enemy, herbivore, and decomposer abundances in flower plantings

Ecosphere, Volume 17, Issue 1, January 2026.
Abstract Flower plantings in agricultural landscapes can contribute to sustainable crop production by enhancing pollination and biological control services. However, selecting plant species that promote multiple ecosystem services is challenging, since plants that favor pollinators may not equally foster natural enemies, and potential trade‐offs, such ...

L'impact du miellat de puceron au niveau des relations tritrophiques entre les plantes-hôtes, les insectes ravageurs et leurs ennemis naturels [PDF]

Biotechnologie, Agronomie, Société et Environnement, 2009
Aphid honeydew impact on the tritrophic relationships between host-plants, phytophagous insects and their natural enemies. Tritrophic relations between plants, phytophagous insects and beneficials are based on the presence of chemical cues in the ...

Fly pollinator foraging in boreal forests is shaped by climate, forest structure and flower resources

Oikos, Volume 2026, Issue 1, January 2026.
Most insect pollinators are ectothermic and rely on external heat sources for temperature regulation. Forests, with their diverse canopy structures and sunlight penetration levels, create a mosaic of microclimates influencing these insects' behaviour.
