“…Th rips tabaci is also a major vector of Iris yellow spot virus (IYSV) that can cause yield losses of up to 100% Birithia et al 2013). Onion thrips can reproduce asexually (parthenogenesis) and sexually and the most common reproductive mode is thelytoky, a parthenogenesis in which females are produced from unfertilized eggs (Gill et al 2015).…”

Biological parameters of the onion thrips, Thrips tabaci Lindeman were studied on the following onion (Allium cepa L.) cultivars: Nasik Red Plus N-53, Onion Dr-301 (Krishna), Onion White, and Nasik Red, at 25±1 o C and 65±5% RH. Signifi cant (p < 0.05) diff erences were found in the life stages and fertility life tables on diff erent cultivars except in the pupal stages. More information about the biological parameters of T. tabaci on onion cultivars can help in designing Integrated Pest Management programs for onion thrips.

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. Since morphometric key-based thrips identification based on the adult stage is time-consuming, there is a need to develop diagnostic tools which are rapid, accurate, and independent of developmental stages. Here, we report a multiplex PCR assay to identify four major thrips vectors viz. Thrips palmi, T. tabaci, Scirtothrips dorsalis, and Frankliniella schultzei present in India. Results: Cytochrome oxidase subunit III and internal transcribed spacer region 2 were utilized to design speciesspecific primers. Of 38 pairs of primers tested, primer pairs AG35F-AG36R, AG47F-AG48R, AG87F-AG88R, and AG79F-AG80R amplified 568 bp, 713 bp, 388 bp, and 200 bp products from the DNA templates of T. palmi, S. dorsalis, T. tabaci, and F. schultzei, respectively at same PCR conditions. The specificity of the primer pairs was validated with a large number of known specimens and no cross-reactivity was observed with other thrips species. The multiplex PCR assay with a cocktail of all the four primer pairs detected four thrips vectors efficiently and could discriminate all of them concurrently in a single reaction. Conclusion: The multiplex PCR reported in this study could identify the major thrips vectors reported in India. The assay will be useful in ascertaining distribution profile of major thrips vectors, disease epidemiology, screening large samples, and quarantine.

“…Insect pests that can cause damage include onion maggot [Delia antiqua (Meigen)], seedcorn maggot [Delia platura (Meigen)], aster leafhopper (Macrosteles quadrilineatus Forbes), leek moth [Acrolepiopsis assectella (Zeller)], aphids (Hemiptera: Aphidae), cutworms (Lepidoptera: Noctuidae), leafminers (Diptera: Agromyzidae), and thrips (Thysanoptera: Thripidae). Of these, onion thrips (Thrips tabaci Lindeman) is often described as the most damaging pest of onion (Diaz-Montano et al, 2011;Gill et al, 2015). Onion thrips feeding results in leaf tissue silvering and photosynthesis reduction leading to bulb size reduction and yield loss (Childers, 1997).…”

Soil conservation practices for insect pest management in highly disturbed agroecosystems – a review

Decline in soil health is a serious worldwide problem that decreases complexity and stability of agricultural ecosystems, commonly making them more prone to outbreaks of herbivorous insect pests. Potato (Solanum tuberosum L., Solanaceae) and onion (Allium cepa L., Amaryllidaceae) production is currently characterized by high soil disturbance and heavy reliance on synthetic inputs, including insecticides. Evidence suggests that adopting soil conservation techniques often (but not always) increases mortality and decreases reproductive output for the major insect pests of these important vegetable crops. Known mechanisms responsible for such an effect include increases in density and activity of natural enemy populations, enhanced plant defenses, and modified physical characteristics of respective agricultural habitats. However, most research efforts focused on mulches and organic soil amendments, with additional research needed on elucidating effects and their mechanisms for conservation tillage, cover crops, and arbuscular mycorrhizae.
