The western flower thrips [Frankliniella occidentalis (Pergande)] is an invasive pest insect in agriculture. This species of thrips is native to the Southwestern United States [1] but has spread to other continents, including Europe, Australia (where it was identified in May 1993 [1]), and South America via transport of infested plant material.
For instance, western flower thrips are known to love pale roses with strong fragrances, but they aren’t as interested in scent-free, dark roses that produce tight flower buds. 9. Use Reflective ...
Flower thrips can be agricultural pests in either two species of thrips in the genus Frankliniella: F. tritici , Eastern flower thrips F. occidentalis , Western flower thrips
This species is an aggressive predator and will feed on the immature stages of western flower thrips, common blossom thrips, onion thrips, melon thrips and chilli thrips, as well as the silverleaf whitefly and Asian citrus psyllid, and several plant-damaging mites. It is most successful with prey feeding on foliage, and less so with those in ...
The first report of the use of an insect species to control an insect pest comes from "Nanfang Caomu Zhuang" (南方草木狀 Plants of the Southern Regions) (c. 304 AD), attributed to Western Jin dynasty botanist Ji Han (嵇含, 263–307), in which it is mentioned that "Jiaozhi people sell ants and their nests attached to twigs looking like ...
The cultured mites can be mixed with bran and sprinkled on the crop or spread by air blast. When multiple species of pest are present, it may effectively control one but not another; for example, in field grown cucumbers, it was found to control melon thrips on leaves, but failed to control common blossom thrips on flowers.

Dicyphus hesperus has also been tested as a biological control for the western flower thrips (Frankliniella occidentalis) on tomatoes. It was effective at reducing the number of thrips but when the ratio of predator to prey was too high (>1:10), some damage was caused to the tomato fruits by D. hesperus. [7]
Thrips develop resistance to insecticides easily and there is constant research on how to control them. This makes thrips ideal as models for testing the effectiveness of new pesticides and methods. [90] Due to their small sizes and high rates of reproduction, thrips are difficult to control using classical biological control. Suitable ...
