مقاومت القایی در فلفل رنگی بوسیله قارچTichoderma harzianum T22 و جاسمونیک اسید روی پراسنجه-های جدول زندگی کنه شکارگر Amblyseius swirskii

The predator mite, Amblyseius swirskii (Acari: Phytoseiidae), is one of the effective and polyphagous biological control agents that feeds on different pest species such as, thrips, whiteflies, and two spotted spidermites. Currently, it uses to control of western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae), but in times of outbreak and high density of the pest population, its efficiency is reduced and it is necessary to use complementary methods to control the pest damage. In this study, Induced resistance in bell peppers (Lorca variety) with Jasmonic acid (JA, 0.5 mM), Trichoderma harzianum T22 (Th, 10 ml per plant from 107 spore/ml suspension) and, the combination of Jasmonic acid with T. harzianum (JA + Th) was investigated on the biological characteristics and life table parameters of A. swirskii reared on the western flower thrips. The experiment was carried out with 80 replications for each treatment in constant environmental conditions (25 ± 1°C, 65 ± 5% RH and 16:8 h light: dark). Based on the results, the longest development time of immature stages (9.41 days) and the shortest female adult longevity (24.92 days) were observed in JA + Th treatment. All the life table parameters showed a significant difference. The highest and lowest values of intrinsic rate of increase, net reproductive rate and, finite rate of increase was estimated for control and JA + Th treatment, respectively. The results of this study could be used in the application of A. swirskii with JA + Th treatment in integrated management programs of WFT.
