Preliminary notes on the behaviour of adult fruit flies Anastrepha striata Schiner, under laboratory conditions
The behaviour of adults of the tephritid Anastrepha striata collected from guava plantations in Costa Rica was studied under laboratory conditions. Oviposition behaviour was observed on 5 species of ripe fruit. Guava and Psidium friedrichsthalianum were the most attractive fruits for oviposition (100 percent oviposition), there was less oviposition (20 percent) on Spondias dulcis and no oviposition on mango and avocado fruits. Greatest adult activity was observed between 9.00 and 14.00 h under high light intensity. Under cloudy or cold conditions there was little adult activity. Both low (18 deg C) and high (28 deg C) temperatures negatively affected adult activity and survival. Notes on pre-oviposition behaviour and intraspecific competition on larval substrate are given.
