Scirtothrips mangiferae Priesner
Common name: Mediterranean mango thrips.
Geographical distribution: The Middle East, Iran and East Africa.
Life history: The pest raises 3-4 annual generations. During winter it hides within mango buds, later moving onto the inflorescences and the setting fruits. Its numbers increase in spring (unless reduced by khamsins) and summer, surge by late-summer, decline in autumn. Reproduction is apparently by parthenogenesis, as males are very rare.
Economic importance: Feeding on the foliage causes curling, distortions, and drop, especially of young leaves, and twig shortening. infested fruits show silvery spots that turn brown, reducing their market value.
Monitoring: Sticky yellow traps. An economic injury level was suggested: when 10 pests/young twig were found, a pesticide application was required.
