Citrus thrips: biology, ecology, and control.

Abstract

In this technical bulletin from the USA, the authors review current knowledge and research accomplishments to mass rear the citrus pest Scirtothrips citri (Moult.) under greenhouse conditions on California sumac (Rhus laurina); to define the developmental growth parameters of S. citri under different temperature regimes; to develop an inexpensive and effective emergence-dispersal monitoring trap; to associate the thermal heat accummulation, in day-degrees, with the concept of thrip-days accumulation; to validate a nearly, real-time, temperature-driven simulation model, SIMDEV, to predict cohort field life-stage distribution; to evaluate the insecticidal tactic of controlling metamorphosis of S. citri with ground cover spray applications; to evaluate the impact of various weed ecosystems on thrips population levels and their effects on Valencia orange fruit quality; and to determine the biological control role of the predacious mite Amblyseius hibisci (Chant) and its potential for early season population suppression of S. citri.
