SURVEY OF PREDATORY COCCINELIDS (COLEOPTERA, COCCINELLIDAE) IN CITRIC PLANTS.
Abstract
Predatory coccinelids were surveyed in citric plants fortnightly at orchards in Viamão for 4 months (from August to November, 1998) and in Porto Alegre for 5 months (from December, 1998 to April, 1999), Rio Grande do Sul state. The research was conducted at private properties where insecticides were not used in the orchards. Baiting trays were used randomly to catch the specimens. Thirteen species of 13 genera totaling 276 specimens were collected, with the predominance of lady beetles Coccidophilus citricola Bréthes, 1905, which feed preferentially on scale insects of the family Diaspididae.
