Rearing technique of palm thrips, Thrips palmi Karny, with microscope concave slides.

The nymph and adult of Thirps palmi Karny were reared in microscope concave slides (MCS) consisting of two microscope concave slides(with 25.4mm× 76.2mm of slides size and 18mm of alcove diameter) and a piece of eggplant leaf (10mm × 10mm) with enough food supplied and humidity kept. This MCS rearing technique of palm thrips is not only simple in apparatus, and effective in keeping thrips from escaping, but also easy to operate and observe under the microscope. With this rearing technique, the survival rate from nymph to adult were 77.78% ,65.96% ,82.61% ,66.67% and 56.52% under 20C,25C,28C ,30C and 32C respectively.
