VARIETIES OF CITRUS MORE SUSCEPTIBLE TO THE ATTACK OF Macropophora accentifer (OLIVIER, 1975) COLEOPTERA, CERAMBYCIDAE

Abstract

The preference for oviposition and/or alimentation was observed in Macropophora accentifer females in a mixed yard, composed by cravo and rio tangerines, baianinha and natal oranges, tangor sabará and cravo lemon. The plants were 5 to 20 years old, and the yard was abandoned and cultivated with a distance of 10m between plants. The females were labeled with dye ink in the pronotum region. Manual collection, labeling, release and recapture were carried out in September/October/November, and in March/April/May. A total of 231 females insects were collected in each variety, labeled and immediately released in different varieties, including those who collected firstly. The recaptures were carried out twelve days after each release; 30 releases and 50 recaptures were performed. The preference was determined considering the number of female insects that remained, returned or migrated to each one of the citrus varieties. It was observed that 2.16% of the females returned to the varieties where they were previously collected, 59.31% remained in the variety where they were released, 30.74% migrated to different varieties, and 7.79% were not recaptured. The cravo tangerine presented 46.75% of preference, followed by tangor sabará with 16.88%, baianinha orange with 10.82%, natal orange with 9.95% and rio tangerine with 7.8%. Cravo lemon did not present any preference by the insect females.
