Phytoseiid mites have no eyes and therefore rely on volatiles released by damaged plants and their tactile [...] The predatory mite Phytoseiulus persimilis is by far the most important natural enemy of Two-spotted spider mite (Tetranychus urticae) and has been used [...] mites increases rapidly, and they quickly reduce the spider mite population by predation. Phytoseiulus persimilis is highly specific and is only effective

The fourth larva stadium develops into a white, oval case encircled by a ring of erect waxy rods. This is called the pupa stadium and these pupae

• Green peach aphid

In greenhouses reproduction also takes place by parthenogenesis, with unfertilized viviparous females continuing to produce
