Sexual morphs and biology of Aphis verbasci Schrank (Hemiptera: Aphididae).
The oviparous female and wingless male of Aphis verbasci from Poland and the United Kingdom are described and illustrated in detail for the first time, with notes on biology, distribution and host plants.
متن کاملMorphological discrimination of Aphis gossypii (Hemiptera: Aphididae) populations feeding on Compositae.
Aphis gossypii Glover is a polyphagous aphid pest with a worldwide distribution. However, there is evidence that on a global scale the name A. gossypii is being applied to a number of forms with different life cycles and/or host-plant associations. Morphometric variation of A. gossypii samples from crops and non-cultivated plants in many parts of the world was examined, to determine whether thi...
متن کاملPopulation dynamics of Aphis glycines (Homoptera: Aphididae) and impact of natural enemies in northern China.
Field surveys of soybean aphid, Aphis glycines Matsumura, and its natural enemies, as well as natural enemy exclosure experiments, were conducted during 2003 and 2004 in soybean fields near Langfang, China. In 2003, aphid density increased six-fold during 12 d in July from 66+/-12 per 10 plants to a seasonal peak of 401+/-79 per 10 plants. Aphid density remained high for another 10 d and declin...
متن کاملEvaluation of artificial diets for rearing Aphis glycines (Hemiptera: Aphididae).
Artificial aphid diets have been previously developed for the pea aphid, Acyrthosiphon pisum (Harris), and the green peach aphid, Myzus persicae (Sulzer). The ability to rear aphids on an artificial diet allows for selectively adding or subtracting compounds from an aphid's food source to determine the effect on fecundity and longevity. Five diets previously developed for the green peach aphid ...
متن کاملCollective Defense of Aphis nerii and Uroleucon hypochoeridis (Homoptera, Aphididae) against Natural Enemies
The prevalent way aphids accomplish colony defense against natural enemies is a mutualistic relationship with ants or the occurrence of a specialised soldier caste typical for eusocial aphids, or even both. Despite a group-living life style of those aphid species lacking these defense lines, communal defense against natural predators has not yet been observed there. Individuals of Aphis nerii (...
