Plant-mediated interactions between whiteflies, herbivores, and natural enemies.
Whiteflies (Homoptera: Aleyrodidae) comprise tiny phloem-sucking insects. The sessile development of their immatures and their phloem-feeding habits (with minimal physical plant damage) often lead to plant-mediated interactions with other organisms. The main data come from the polyphagous pest species Bemisia tabaci (Gennadius) and Trialeurodes vaporariorum (Westwood), which are intricately ass...
متن کاملTrophic Relationships between Aphids and Their Primary Parasitoids
The present research was carried out to study the trophic relationship between aphids and their primary parasitoids in Pothwar, Pakistan during 2009-2010 in the districts of Rawalpindi, Attock, Chakwal, and Jhelum. Ten species of aphids were recorded from 17 host plants. The aphids were parasitized by 11 species of primary parasitoids. Five quantitative aphid-parasitoid food webs were construct...
متن کاملInfochemical-tritrophic Interactions of Soybean Aphids-host Plants-natural Enemies and Their Practical Applications in Pest Management
The soybean aphid, Aphis glycines Matsumura, is a newly invasive insect species that seriously threatens U.S. soybean production. This aphid pest has kept haunting many soybean growers by developing large colonies on soybeans in North America since 2000. Since its first appearance in Wisconsin, it has spread to over half of US states and southern provinces in Canada. The heavy infestation of th...
متن کاملEffects of Wheat-Maize Intercropping on Population Dynamics of Wheat Aphids and Their Natural Enemies
To study the effects of wheat-maize intercropping on the population dynamics of wheat aphids and their natural enemies, wheat-maize intercropping patterns were divided into four levels: 8:2, 6:2, and 4:2 intercropping, and monoculture wheat. The results showed that as the wheat coverage rate decreased, the quantities of immigrating winged aphids and their natural enemies significantly differed;...
متن کاملInteractions between transgenic plants, the diamondback moth and natural enemies
Several Brassica crops have been transformed with -endotoxin genes from Bacillus thuringiensis (Bt) to provide resistance to the diamondback moth (Plutella xylostella) and other lepidopteran pests. This paper describes studies of the direct and indirect effects of Bt plants on a parasitoid of P. xylostella using Cry1Acexpressing transgenic oilseed rape (canola) as an example. The braconid wasp ...
