An aphid-dip bioassay to evaluate susceptibility of soybean aphid (Hemiptera: Aphididae) to pyrethroid, organophosphate, and neonicotinoid insecticides.
Since the discovery of the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), in North America in 2000, chemical control has been the most effective method to manage aphid outbreaks. Increased insecticide use in soybean raises the possibility of developing insecticide resistance in soybean aphid, and monitoring insecticide susceptibility is essential to maintain pesticide tools. We...
متن کاملPLANTÐINSECT INTERACTIONS Sorghum as a Trap Crop for Nezara viridula L. (Heteroptera: Pentatomidae) in Cotton in the Southern United States
The southern green stink bug, Nezara viridula L., may disperse from alternate host plants, especially corn,ZeamaysL., andpeanuts,Arachis hypogaeaL., into cotton,Gossypiumhirsutum L. Trap crops may be useful to intercept dispersing stink bugs. Therefore, the ability of sorghum, Sorghum bicolor L. Moench, to trap N. viridula adults in cotton was studied for 3 yr. The 2002 experimentwas designed t...
متن کاملBiology of the Soybean Aphid, Aphis glycines (Hemiptera: Aphididae) in the United States
The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is a significant insect pest of soybean in the north-central region of the United States and southern Canada, and if left untreated can reduce yield value by $2.4 billion annually. The soybean aphid is native to eastern Asia, where soybean was first domesticated, and was first detected in the United States in 2000. It quickly s...
متن کاملWithin-plant distribution of cotton aphid (Hemiptera: Aphididae) in cotton cultivars with colored fibers.
We describe the vertical and horizontal distribution of the cotton aphid Aphis gossypii Glover within a cotton plant in two cotton (Gossypium hirsutum Linnaeus) cultivars (BRS Safira and BRS Rubí) with colored fiber over the time. Measurements of aphid population dynamics and distribution in the cotton plants were recorded in intervals of seven days. The number of apterous or alate aphids and t...
متن کاملPLANT RESISTANCE Plant Responses to Seven Russian Wheat Aphid (Hemiptera: Aphididae) Biotypes Found in the United States
The Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), is a serious wheat, Triticum aestivum L., and barley, Hordeum vulgare L., pest throughout the small grain-producing areas in the western United States. The virulency and classiÞcation of recently described Russian wheat aphid biotypes 1Ð7 (RWA1Ð7) were clariÞed using 24 plant differentials. These seven biotypes had bee...
