Article Synopsis
- Plant bugs and thrips are major pests in U.S. cotton production that aren't effectively managed by current transgenic cotton varieties, often requiring chemical insecticides.
- A study showed that the transgenic cotton variety MON 88702 significantly reduces Lygus nymphs and thrips, leading to better crop yields and minimal damage compared to non-transgenic counterparts treated with insecticides.
- The findings suggest MON 88702 could be a valuable tool in integrated pest management (IPM) programs to combat these pests amidst increasing resistance to traditional insecticides.
The spectrum of insecticidal activity of Cry51Aa2.834_16 protein targeting hemipteran and thysanopteran insect pests in cotton was characterized by selecting and screening multiple pest and non-pest species, based on representation of ecological functional groups, taxonomic relatedness (e.g.

A total of 41 strains was sampled, and most of them were collected from Bt cotton planting regions. The range of IC50 values (concentration producing 50% inhibition of larval development to third instar) among different populations in 1998,1999, and 2000 were 0.
