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 ...

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.

Another way that avocado farms try to maintain the threat is to have modified fruit harvesting strategies to eliminate breeding and feeding sites of the thrips. [13] Another usage of parasitoids was used in 2001 in New Zealand to control the greenhouse thrips. [8] The parasitoid Thripobius javae is typically a predator of the H. haemorrhoidalis.
