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.
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.
Organic control requires all of the non-insecticide methods (aggressive weeding, wasps, virus) plus Bacillus thuringiensis ssp. aizawai or Entrust which contains spinosad. [21] The Western Flower Thrips is common here. [23] Organochlorines were used until being replaced in the 1970s by carbamates and organophosphates. [23]
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 ...
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 ...
Western Flower Thrips (Frankliniella occidentalis) is a major pest of horticulturals around the world. [295] Here, it is especially known as a pest of peach [292] and strawberry. [296] [295] (See also § Cultivars of strawberry, § Arthropods in peach, § Pests of strawberry.) The Diamondback Moth (Plutella xylostella) is a common insect pest ...
