Retithrips syriacus Mayet 1890 - (castor thrips)

This thrips is found mainly in tropical regions and has been recorded from parts of Africa, western Asia and in some isolated pockets of Florida, the Caribbean and South America. It has not been recorded from Europe (EFSA Panel on Plant Health, 2021). It is polyphagous, with common host plants being fruit trees and grapevine.

Males emerge from unfertilized eggs, but R. syriacus can also reproduce parthenogenically. Females lay their eggs into leaf tissue and the emerging larvae complete their development within 1-2 weeks. The mature larvae drop to the ground and pupate in the soil. There are several generations per year.
