The objective of this study was to evaluate the population dynamic of Scymnus spp. and Anastrepha spp. and their correlations between meteorological factors in an experimental semi-organic guava (Psidium guajava L.) orchard in the experimental field of APTA (Agência Paulista de Tecnologia dos Agronegócios) in Pindorama, SP. For the survey of population dynamic, the specimens were collected with yellow sticky traps (25 cm x 9.5 cm) which were replaced every 15 days in a period of one year (between June 2009 and June 2010). It was observed the occurrence of Scymnus spp. and Anastrepha spp. throughout the sampling period. The insects were assessed and quantified at the Laboratory of Ecological Selectivity at FCAV-UNESP in Jaboticabal-SP. Based on the results obtained and the conditions of development of this study, it was possible to conclude: a) There is an increase in population of Anastrepha spp. with the increase of minimum, average and maximum temperatures; b) The population peak of Anastrepha spp. occur from January to March and coincides with the period of availability of ripe fruits in the guava orchard; c) The highest occurrences of predator Scymnus spp. were from September to December and the lowest rates in February and March d) The rainfall did not interfere in the population dynamic of Scymnus spp. and Anastrepha spp.
