WIKIPEDIA - Frankliniella occidentalis Un article de Wikipédia, l'encyclopédie libre. Le thrips des petits fruits, ou thrips californien (Frankliniella occidentalis (Pergande)), est un important insecte ravageur des cultures. Cette espèce de thrips est originaire d'Amérique du Nord mais s'est répandue dans les autres continents dont l'Europe, l'Australie et l'Amérique du Sud à la faveur de la dispersion de plantes infectées[1]. Description[modifier | modifier le code] Le mâle adulte a environ 1 millimètre de long, la femelle est légèrement plus grande, environ 1,4 millimètre de long. Cycle biologique[modifier | modifier le code] Le cycle biologique du thrips des petits fruits a une durée variable car les adultes peuvent vivre de deux à cinq semaines ou plus et la nymphe peut vivre de 5 à 20 jours. Dégâts[modifier | modifier le code] L'insecte attaque les plantes de plusieurs manières.

STELLENBOSCH UNIVERSITY - NOV 2016 - Thèse en ligne : Developing an integrated management system for western flower thrips, Frankliniella occidentalis (Pergande), on deciduous fruit, using semiochemicals in a push-pull strategy ENGLISH ABSTRACT: Western flower thrips (WFT), Frankliniella occidentalis (Pergande), causes both feeding (russetting and silvering) and oviposition (pansy spot) damage to fruit. Despite routine insecticide applications from 20% bloom until petal fall, pansy spot and pitting damage was still being reported, particularly on plums. This study was initiated to determine the reason for the apparent failure of chemical control and the cause of pitting damage, and to investigate the feasibility of developing a push-pull system to minimize economic WFT damage by using deterrent plant essential oils and trap crops. Field trials in commercial plum orchards in the Western Cape confirmed that WFT oviposition causes pitting damage.

ANNUAL REPORT OF THE KANSAI PLANT PROTECTION SOCIETY - 2021 - Toxicities of insecticides against two species of flower thrips collected from strawberry plants in Nara Prefecture Abstract Effects of six insecticides were investigated on two species of flower thrips, Frankliniella occidentalis (Pergande) and F. intonsa (Trybom), collected from strawberry greenhouses in Nara Prefecture. Spinosad was found to be the most effective insecticide against two species of flower thrips in terms of corrected mortality and leaf damage. Fluxametamide was found to be an effective insecticide. INSECTS 24/05/22 Fumigant Toxicity of Essential Oils against Frankliniella occidentalis and F. insularis (Thysanoptera: Thripidae) as Affected by Polymer Release and Adjuvants Frankliniella occidentalis is among the most economically significant pests of greenhouse crops, whose resistance to conventional insecticides has created demand for biopesticides such as essential oils. We assessed the fumigant toxicity of linalool against F. occidentalis, F. insularis, and Solanum lycopersicum. Thrips were fumigated with polyacrylamide hydrogels containing either (R)-linalool, (S)-linalool, racemic linalool, or a binary mixture of (R)-linalool with one of twelve adjuvants (i.e., peppermint, cedarwood, neem, clove, coconut, jojoba, soybean, olive, α-terpineol, 1,8-cineole, trans-anethole, or (R)-pulegone). Solanum lycopersicum seedlings were exposed to (R)-linalool or a mixture of (R)-linalool and peppermint oil via conditioned hydrogels or foliar spray. For F. insularis, (R)-linalool was more toxic than (S)-linalool, with LC50 values of 11.7 mg/L air and 16.7 mg/L air, respectively. ►▼ Show Figures Figure 1

AGRONOMY 23/09/21 Infection of the Western Flower Thrips, Frankliniella occidentalis, by the Insect Pathogenic Fungus Beauveria bassiana The western flower thrips, Frankliniella occidentalis, is an aggressive agricultural insect pest causing significant damage to a wide range of fruit, vegetable, and ornamental crops. Beauveria bassiana is a broad-host-range entomopathogenic fungus capable of infecting and killing F. occidentalis. Infection of thrips by B. bassiana strain BbYT12 using a concentration of 1 × 108 conidia/mL resulted in 81.48% mortality in adults in 6 d (LT50 = 90 ± 15.1 h). Scanning electron microscopy of the infection process revealed preferential adhesion and germination of fungal spores to inter-segmental folds or grooves on the insect body surface with penetrating germlings and extended hyphae visualized during the initial stages of infection (6–24 h). Histological analyses showed the appearance of in vivo hyphal bodies in sagittal sections and the fat body as early as 24 h post-infection. ►▼ Show Figures Graphical abstract

Crop Protection Volume 153, March 2022, Susceptibility levels of field populations of Frankliniella occidentalis (Thysanoptera: Thripidae) to seven insecticides in China The western flower thrips, Frankliniella occidentalis (Pergande), is an important pest of a wide range of vegetables, fruits, and ornamental plants (Kirk and Terry, 2003; Reitz, 2009; Reitz et al., 2011). Frankliniella occidentalis not only scars the leaves, flowers, and fruits of plants, but also transmits a variety of plant viruses, including tomato spotted wilt orthotospovirus (TSWV), impatiens necrotic spot virus (INSV), and maize chlorotic mottle virus (MCMV), which cause catastrophic losses to a wide range of crops (Jones, 2005; Whitfield et al., 2005; Zhao et al., 2014). Frankliniella occidentalis originated in the mountains of western North America but spread rapidly throughout the world with the increase in international trade (Kirk and Terry, 2003). Since its first introduction in China in 2003 (Zhang et al., 2003), F. occidentalis has become a limiting factor in the production of horticultural crops (Wu et al., 2007, 2018; Zhang et al., 2007).
