Damage by thrips
Thrips can injure many crops with different ways. The injured leaves show a grey or silver color by the feeding of thrips. In addition, thrips excrements can lower the value of ornamental crops. Thrips eggs are laid in the leaf tissue and can cause warty suberizations. In different crops, deformations and discolorations of the leaf, fruit and flowers can be detected. Thrips are also known vectors of many viruses.
    Amblyseius swirskii mainly prey on the young larvae of thrips. Its efficiency of biocontrol for thrips is better than that of Amblyseius cucumeris which means that about 5 larvae are consumed in a day.
