Three Decades of China's Bt Cotton: Achievements and Insights
ABSTRACT Cotton is a vital natural fibre crop with significant economic value worldwide. In response to the threat of cotton bollworm (Helicoverpa armigera), the China government initiated a research project in 1992 to develop transgenic Bacillus thuringiensis (Bt) cotton.

“Whiteflies” is the common name of an insect group (Hemiptera: Aleyrodidae) which has around 1556 described species (Martin & Mound, 2007), although only about thirty species have been mentioned in Spain which are included in the table 1 (Martin et al., 2000). The origin of this group of insects is very varied, as its current spread.

Prevalence and genetic diversity of endosymbiotic bacteria infecting cassava whiteflies in Africa [PDF]
Background: Cassava provides over half of the dietary requirement for more than 200 million poor in Africa. In recent years, cassava has been affected by an epidemic of a virus disease called cassava brown streak disease (CBSD) that is spreading in much ...

Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Cassava production systems optimized for double output: Seed‐cuttings and root yields
Abstract Cassava (Manihot esculenta Crantz) is a strategic crop for food security but continues to face major challenges related to low root yields and the lack of optimized systems for producing high‐quality seed‐cuttings. This study evaluated the effects of different planting densities, varieties, and agrochemical‐based seed‐cutting treatments ...

Effects of Alternative Prey Density on Cannibalism in Adult Female Neoseiulus californicus
Using two strains of N. californicus—TU (reared long‐term on T. urticae) and OB (reared long‐term on O. bakeri)—this study demonstrated that although alternative prey density had no significant effect on cannibalism, both rearing strain and conspecific life stage significantly influenced cannibalistic behavior, with a significant interaction between ...
