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.
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. [2]
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 ...
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 ...
They are sites where a female has oviposited into developing flower buds or fruitlets. Despite the cosmetic damage suffered by these light skinned apple cultivars they are seemingly unaffected by most thrip vectored viruses. Infested apples of the mountain west simply provide a natural setting for Western Flower Thrips to thrive and reproduce.
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]
Biological control or biocontrol is a method ... The bug Orius insidiosus has been successfully used against the two-spotted spider mite and the western flower thrips ...
In order to protect their eggs, thrips insert their eggs into various types of plant tissue. Eggs can be found in the stems, leaves, or flowers of plants. [8] Thrips hatch in 2–3 days and complete their life cycle in 20–30 days. [2] Adult thrips feed on the flower bud, stem and leaf parts of the plant. [8]
