Insects and Survival: A Review of Primary and Secondary Defense Strategies
Entomologia Experimentalis et Applicata, EarlyView.Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics
Journal of Applied Entomology, EarlyView.ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...

A multiplex PCR assay for rapid identification of major tospovirus vectors reported in India
BMC Genomics, 2020 Background To date, four thrips vectors have been reported to transmit five different tospoviruses in India. Their identification at an early stage is crucial in formulating appropriate pest management strategies.

Thrips tabaci population genetic structure and polyploidy in relation to competency as a vector of tomato spotted wilt virus. [PDF]
PLoS ONE, 2013 Knowledge of population-level genetic differences can help explain variation among populations of insect vectors in their role in the epidemiology of specific viruses. Variation in competency to transmit Tomato spotted wilt virus (TSWV) that exists among

Seasonal Abundance of Onion thrips, Thrips Tabaci Lindeman. in Sokoto, Nigeria
Journal of Agricultural Science, 2010 Onion seedlings were transplanted from November to March to study the population dynamics of onion thrips, Thripstabaci. There are four transplants in 2001/2002 and five in 2002/2003 seasons. In 2000/2001 season onion plants weregrown in exploratory trials and in 2003/2004, water traps were used to confirm results of the previous experiments.Results ...

Three Decades of China's Bt Cotton: Achievements and Insights
Plant Biotechnology Journal, EarlyView.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.
