A field study was conducted in 2009, 2010, and 2011 on a grower’s field with a known population of glyphosate-resistant giant ragweed to determine potential control options utilizing a Wi...
Field efficacy of seven geographical isolates of Helicoverpa armigera nucleopolyhedrovirus (HaNPV) along with an insecticide control was evaluated against H. armigera on cotton and chickpea in the C...
A baseline survey was conducted to determine the occurrence and distribution of soil nematodes associated with cotton in major growing areas in Kenya. Such baseline data on soil nematode abundance, di...
Functional responses of 2 female coccinellid predators, Scymnus levaillanti and Cycloneda sanguinea, to the cotton aphid, Aphis gossypii, at various temperatures were studied under laboratory conditi...
Cotton at three stages of crop phenological development was infested with eggs and third instar larvae of the fall armyworm, Spodoptera frugiperda (J.E. Smith), to determine the effect of larval feedi...
Traditional agronomic practices are often ineffective in preventing cotton (Gossypium hirsutum L.) yield losses due to the Columbia lance (CLN) nematode (Hoplolaimus columbus Sher), so control relies ...
A survey was undertaken to determine the frequency and abundance of plant-parasitic nematodes associated with cotton (Gossypium hirsutum L.) in Alabama. In the fall seasons of 1998-2000, 969 soil samp...
Field-cage studies have indicated that prefruiting cotton (Gossypium hirsutum L.) is not nutritionally adequate to support extended longevity of overwintered boll weevils (Anthonomus grandis Boheman),...
Cotton (Gossypium hirsutum) experiences frequent episodes of insect infestation during the growing season in Australia. The most important pests are larvae of the cotton bollworm (Helicoverpa armigera...
Several field studies have indicated that cotton fleahoppers (Pseudatomoscelis seriatus Reuter) prefer some wild host plants instead of cotton (Gossypium hirsutum L.). The relative attractiveness of v...
Poor Cry1Ac protein expression was common in the first years of transgenic (Bt) cotton in Australia, when single-gene Cry1Ac cotton (called Ingard in Australia and Bollgard in USA) was grown. Two-gene...
Field trials conducted in northeastern North Carolina in 1994 and 1995 examined the effects of plantings of pure and blended genotypes of Bollgard cotton on (i) the larval population development of ca...
No precise economic injury levels or action thresholds have been established for pests infesting transgenic Bt cotton, Gossypium hirsutum L. This study was designed to quantify the effects of injury t...
Field studies were performed during 2005 and 2006 to determine bollworm, Helicoverpa zea (Boddie), and tobacco budworm, Heliothis virescens (F.), larval behavior on conventional non-transgenic cotton ...
A large percentage of Bollgard cotton is treated for bollworms [Helicoverpa zea (Boddie)] with little information about economic losses from these infestations. The impact of bollworm infestations on ...
