Integrated management of thrips-mite and borer complex attacking chilli

Abstract

Thrips, mite and borer complex are the most serious insect pests which reduce chilli yield remarkably in many chilli growing areas. This study exposed that sustainable bio-rational based management packages including different mechanical approaches and bio-pesticides were effective against Thrips, mite and borer pests in chilli. The results indicated that, spraying of Sodium lauryl ether sulphate (Fizimite) and Matrine (Biotrin) along with blue sticky trap and pheromone mass trapping of Helicoverpa armigera and Spodoptera litura was most effective against Thrips, mites and borer pests. The lowest number of Thrips and fruit borer infestation was observed from spraying of Sodium lauryl ether sulphate (Fizimite) and Matrine (Biotrin) along with blue sticky trap and pheromone mass trapping of Helicoverpa armigera and Spodoptera litura treated plots. The highest yield (20.93 t/ha) and net income (145525 Tk/ha) were also obtained from spraying of Sodium lauryl ether sulphate (Fizimite) and Matrine (Biotrin) along with blue sticky trap and pheromone mass trapping of Helicoverpa armigera and Spodoptera litura treated plots. Only application of chemical insecticides is not effective against the insect pest's population in a longterm. In contrast, mechanical approaches such as sticky trap, pheromone trap as well as different biopesticides are environmental, economical, dependable and that facilitate the Integrated Pest Management (IPM) concept.

Surveillance and Biorational Management of Rugose Spiraling Whitefly, Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) Infesting Coconut to Reduce the Invasion Threat in Bangladesh

“…D-Limonene, known for its strong aroma, is an active ingredient in several pesticide products that can repel RSW. Our ndings align with previous reports indicating that certain bio-pesticides like Fizimite® 10% (Sodium lauryl ether sulfate), Bio clean® 5% SL, Antario® 0.1% (Bacillus thuringiensis), Success® 2.5% SC (Spinosad), and others effectively combat sucking pests in different crops(Hossain et al, 2020;Rashid et al, 2022;Rahman et al, 2023). The incorporation of bio-pesticides signi cantly enhanced pest management programs and proved compatible with various biorational control methods.…”
