Density‐dependent regulation in populations of potato‐colonizing aphids

Autor: Gary H. Sewell, Francis A. Drummond, Andrei Alyokhin

Publikováno v: Population Ecology. 47:257-266

Scarcity of long-term (over 30 years) data series represents a major challenge for an accurate estimation of the role of density-dependent processes in population regulation. We analyzed population densities of the wingless parthenogenic morphs of bu

Changes in A Lady Beetle Community Following the Establishment of Three Alien Species

Autor: Gary H. Sewell, Andrei Alyokhin

Publikováno v: Biological Invasions. 6:463-471

A number of recent studies indicated that establishment of exotic lady beetles (Coleoptera: Coccinellidae) may have adverse affects on native lady beetle species. In the present study, we analyzed changes in coccinellid community inhabiting potato cr

Aphid abundance and potato virus y transmission in imidacloprid-treated potatoes

Autor: Gary H. Sewell, Andrei Alyokhin, Eleanor Groden

Publikováno v: American Journal of Potato Research. 79:255-262

Imidacloprid is a commonly used insecticide that is highly effective in controlling insect pests of potato. The relatively high cost of imidacloprid provides commercial growers with a strong incentive to reduce field application rates. In the present

Differential effects of weather and natural enemies on coexisting aphid populations

Autor: Richard H. Storch, Andrei Alyokhin, Gary H. Sewell, Francis A. Drummond

Publikováno v: Environmental entomology. 40(3)

Study of mechanisms responsible for regulating populations of living organisms is essential for a better comprehension of the structure of biological communities and evolutionary forces in nature. Aphids (Hemiptera: Sternorrhyncha) comprise a large a
