Ecological impact of a secondary bacterial symbiont on the clones of Sitobion avenae (Fabricius) (Hemiptera: Aphididae)
Many insects harbor heritable endosymbionts, whether obligatory or facultative, and the role of facultative endosymbionts in shaping the phenotype of these species has become increasingly important. However, little is known about whether micro-injected endosymbionts can have any effects on aphid clones, which was measured using various ecological parameters. We examined the effects between symb...
متن کاملLarval morphology and development of Aphidius rhopalosiphi (Hymenoptera: Braconidae: Aphidiinae)1
The aphid parasitoid Aphidius rhopalosiphi is the most abundant species of Aphidiinae in cereal fields in northern Europe. Although the larval morphology of other Aphidiinae has been described, the morphology and immature development of A. rhopalosiphi remain unknown. Our goal is to relate growth and larval developmental stages to morphological changes during parasitoid development, using light...
متن کاملExpression differences in Aphidius ervi (Hymenoptera: Braconidae) females reared on different aphid host species
The molecular mechanisms that allow generalist parasitoids to exploit many, often very distinct hosts are practically unknown. The wasp Aphidius ervi, a generalist koinobiont parasitoid of aphids, was introduced from Europe into Chile in the late 1970s to control agriculturally important aphid species. A recent study showed significant differences in host preference and host acceptance (infecti...
متن کاملThe functional response of Aphidius ervi (Haliday)(Hym.: Braconidae, Aphidiinae) to different densities of Sitobion avenae (Fabricius)(Hom.: Aphididae) on two wheat cultivars
The functional response of Aphidius ervi to different Sitobion avenae densities on two wheat cultivars (Sardary and Alvand) was examined in laboratory conditions. Experiments were carried out in test tubes on an F2 lab generation without wheat clusters and also on F2 and F5 generations in pots using wheat clusters. In the tubes, female wasps were exposed to aphid densities of 2, 4, 7, 14, 28, 3...
متن کاملGreenhouse Trials of Aphidius Colemani (hymenoptera: Braconidae) Banker Plants for Control of Aphids (hemiptera: Aphididae) in Greenhouse Spring Floral Crops
Banker plants with Aphidius colemani Viereck were tested in greenhouses in Massachusetts and New York for control of cotton aphid Aphis gossypii Glover, and green peach aphid Myzus persicae (Sulzer) on 2 spring flower crops, pansies ( Viola tricolor hortensis ) and Marguerite daisies ( Argyranthemum hybrid). Banker plants consisted of pots of barley plants infested with the bird cherry-oat aphi...
