ABSTRACT


Carlos Quiroz E.1
 
Research was carried out during 1974-75 y 1975-76, at the La Platina Experimental Station, INIA, in Santiago, Chile, using traps lured with virgin females. The number of males caught was related to fruit damage and number of generations of the tomato moth Scrobipalpula absoluta (Meyrick). Pest activity could be observed from early spring, under certain temperature conditions (higher than 12°C). However, critical damage atarted when males caught in traps were higher than 100. This level was reached from the last week of January and the first of February. On the other hand, 3 generations could have been generated in both years since the end of November until the end of March, with a 30-40 day life cicle period.
