population dynamics of canola aphids and their dominant natural enemies in ahvaz
in this research, population fluctuation of canola aphids and their natural enemies were investigated during 2007-2008. random samples of 50 plants were taken twice a week. mustard aphid (lipaphis erysimi kalt.), green peach aphid(myzus persicae sulzer)and cabbage aphid (brevicoryne brassicae l.) were recorded on canola. however,the mustard aphid with relative frequency of 79% was dominant. the...
متن کاملRelative influence of plant quality and natural enemies on the seasonal dynamics of Bemisia tabaci (Hemiptera: Aleyrodidae) in cotton.
The abundance and distribution of insect herbivores is determined by, among other things, plant quality and natural enemies. These two factors vary temporally and spatially, subsequently affecting seasonal population dynamics. The relative influence of plant quality and natural enemies on the seasonal dynamics of Bemisia tabaci (Gennadius) was investigated in a 3-yr field study in cotton. Plant...
متن کاملSeasonal Phenology and Natural Enemies of Maconellicoccus Hirsutus (hemiptera: Pseudococcidae) in Australia
Foreign exploration for natural enemies of pink hibiscus mealybug, Maconellicoccus hirsutus , was conducted in Australia from 2000 to 2002. In Queensland, the predaceous beetle Cryptolaemus montrouzieri , the predaceous drosophilid fly, Cacoxenus perspicax and the encrytid parasitoid Gyranusoidea indica were recovered. In Western Australia and the Northern Territory a predatory noctuid , Mataeo...

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;...
