ABSTRACT Western flower thrips, Frankliniella occidentalis (Pergande), is one of the most destructive insect pests of greenhouse production systems with the ability to develop resistance to a wide variety of insecticides. A common resistance management strategy is rotating insecticides with different modes of action. By incorporating entomopathogenic organisms (fungi and bacteria), which have discrete modes of action compared to standard insecticides, greenhouse producers may preserve the…

In order to avoid the prospect of insecticide resistance developing in western flower thrip populations, greenhouse producers must implement a multitude of plant protection strategies including scouting, insecticide rotations, insecticides mixtures, and the use of alternative insecticides with broad-spectrum modes of action.

Evaluation of Entomopathogenic Fungi Against the Western Flower Thrips (Thysanoptera: Thripidae) Under Laboratory Conditions

Adult western flower thrips were more susceptible than larvae to maximum rates of unexpired B. bassiana and I. fumosoroseus, and there was no evidence of any enhanced efficacy when combining azadirachtin with B.bassiana or I.fumosOroseus.

Effect of Integrating the Entomopathogenic Fungus (Hypocreales: Cordycipitaceae) and the Rove Beetle (Coleoptera: Staphylinidae) in Suppressing Western Flower Thrips (Thysanoptera: Thripidae) Populations Under Greenhouse Conditions

Abstract Western flower thrips, Frankliniella occidentalis (Pergande), is a destructive insect pest in greenhouse production systems. Therefore, integrating the entomopathogenic fungus, Beauveria

Pesticidal Evaluation of Entomopathogenic Fungi and Selected Medicinal Plants against Cabbage Aphid (Brevicoryne brassicae L.)

It revealed that a given combination displayed considerable efficacy to reduce B. brassicae (aphids) infestation, and products of fungal isolates and plant extracts should be used for further tests against other insect pests.

Efficacy of biopesticides on spotted wing drosophila, Drosophila suzukii Matsumura in fall red raspberries

It is found that sabadilla alkaloids and Chromobacterium subtsugae both reduced the number of Drosophila larvae in raspberry fruit, and either of these biopesticides could be used as effective rotation partners along with spinosad for control of D. suzukii.

Infection of the Western Flower Thrips, Frankliniella occidentalis, by the Insect Pathogenic Fungus Beauveria bassiana

Real-time RT-PCR analyses of the expression of select genes implicated in virulence including the Pr1 protease, beauvericin synthase, and protein kinase A signaling factors revealed discrete patterns of infection-time dependent expression provide basic insights into the process of B. bassiana infection of F. occidentalis.

Control of thrips (Enneothrips flavens Moulton.) with synthetic and biological insecticides in different peanut genotypes

The synthetic insecticide Engeo Pleno showed of 39% higher efficiency (as average) for controlling thrips in peanut than biological and synthetic insecticides, showing tolerance to 'E. flavens' in peanut, but further studies are needed to better define the application date and products doses.


The insect pest Thrips parvispinus Karny (Thysanoptera: Thripidae) was found to be the most dominant in attacking large chili plants. These insects can be found on all parts of the chili plant,

Integrated pest management in western flower thrips: past, present and future

The main control tactics in integrated pest management of Western flower thrips are reviewed, with the focus on biological control and host plant resistance as areas of major progress.



Western Flower Thrips (Frankliniella occidentalis) Management on Ornamental Crops Grown in Greenhouses: Have We Reached an Impasse?

It is important that greenhouse producers preserve the longevity of currently existing products by establishing rotation schemes based on different modes of action and utilize sanitation and biological control practices to avoid solely relying on insecticides.

Efficacy of Pesticide Mixtures Against the Western Flower Thrips (Thysanoptera: Thripidae) Under Laboratory and Greenhouse Conditions

All binary mixtures used in greenhouses were visibly compatible, and not phytotoxic to any of the plant species evaluated, and the mixture containing spinosad + bifenazate appeared to be antagonistic against western flower thrips.

Management Strategies for Western Flower Thrips and the Role of Insecticides

Today, the western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is one of the most significant agricultural pests globally because of the damage it is able to


Populations of western flower thrips from commercial greenhouses were resistant to deltamethrin, but deltAMethrin mixed with piperonyl butoxide or endosulfan was synergistic in all cases, and none of the populations wereresistant to all of the insecticides tested.

Insecticide Resistance in the Western Flower Thrips, Frankliniella occidentalis

It appears that resistance in F. occidentalis is polyfactorial; different mechanisms can confer resistance in different populations and different mechanisms may coexist in the same population.

Evaluation of existing and new insecticides including spirotetramat and pyridalyl to control Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) on peppers in Queensland.

The trials demonstrated that some insecticides permitted for use against F. occidentalis are not effective and identified a number of insecticides, including the new ones spirotetramat and pyridalyl, that are effective and that could be used to manage the pest within a resistance management program.

Resistance of Greenhouse, Laboratory, and Native Populations of Western Flower Thrips to Spinosad

Resistance to an insecticide with a novel mode of action, such as spinosad indicates the necessity of rotating insecticides and implementing alterna- tive methods of managing western flower thrips.

Comparison of two methods of monitoring thrips populations in a greenhouse rose crop

It is demonstrated that it is accurate to estimate thrips populations using yellow sticky traps (YST) in rose crops in greenhouse and the possibility of setting a damage threshold using the data from the YST in the greenhouse is discussed.

Compatibility between the entomopathogenic fungus Beauveria bassiana and insecticides used in coffee plantations

The use of Alpha-Cypermethrin and Thiamethoxam formulations in coffee IPM programs for a B. bassiana inoculum conservation strategy are recommended, since these products were compatible with the entomopathogenic fungus Beauveria bassiana, an important natural control agent of the coffee berry borer, Hypothenemus hampei.

Biology and Ecology of the Western Flower Thrips (Thysanoptera: Thripidae): The Making of a Pest

This review addresses questions regarding the biological and ecological attributes of western flower thrips that have enabled it to become a significant pest and make it so difficult to manage.
