Aphid symbionts and endogenous resistance traits mediate competition between rival parasitoids
Insects use endogenous mechanisms and infection with protective symbionts to thwart attacks from natural enemies. Defenses that target specific enemies, however, potentially mediate competition between rivals and thereby impact community composition. Following its introduction to North America to control pea aphids (Acyrthosiphon pisum), the parasitoid Aphidius ervi competitively displaced othe...

متن کاملEvidence for specificity in symbiont-conferred protection against parasitoids.
Many insects harbour facultative symbiotic bacteria, some of which have been shown to provide resistance against natural enemies. One of the best-known protective symbionts is Hamiltonella defensa, which in pea aphid (Acyrthosiphon pisum) confers resistance against attack by parasitoid wasps in the genus Aphidius (Braconidae).We asked (i) whether this symbiont also confers protection against a ...
متن کاملComparison effect of ethanolic seed extract of Melia Azedarach L. (Meliaceae) against two Aphid species
Background & Aim: Aphids are of serious pests and vectors of multitude of viral diseases of field crops, vegetables, and greenhouse crops. They have displayed a remarkable ability to establish resistance to almost every insecticide with which it has been treated. To reduce the damage of these pests and dependence on the sometimes unwise use of synthetic pesticides in crop and vegetable plan...
متن کاملCulture of an aphid heritable symbiont demonstrates its direct role in defence against parasitoids.
Heritable symbionts are common in insects with many contributing to host defence. Hamiltonella defensa is a facultative, bacterial symbiont of the pea aphid, Acyrthosiphon pisum that provides protection against the endoparasitoid wasp Aphidius ervi Protection levels vary among strains of H. defensa that are differentially infected by bacteriophages named APSEs. By contrast, little is known abou...
