Resumo
The present study refers to the \occurrence and damage caused by Compsocerus violaceus (Coleoptera, Cerarnbycidae) in a mixed citric yard, maintained without cultivation care, and composed by 357 plants, including rio and cravo taDgerines, baiaoioha and natal oranges, taogor sabara an cravo lemon. The occurrence and damage caused by the larvae was verified in loco in each plant of lhe yard. Toe counts were made considering lhe attacked plants and branches, lhe number of larvas in each branch and the diameter of lhe attacked branches. The biological cycle in fiel d conditions and the number of eggs by dissected females were also observed. Eggs 1aying was observed in clefts in lhe branches. Ao average of 83 eggs was obtained for 11 dissected female insects, with a maximum of 132 and a minimum of 63 eggs per insect. The biological cycle, ranging from egg to adult, was of about 1 O months. After eclosion, the grubs guilt a gallery in the sub cortical region of lhe branches, attacking branches with diameters betweeo 2 to 6 cm. Toe majority of such galleries reach a kind of annealing structure around lhe branch, resulting in lhe dry up and brake of 41.3% of the branches by the action of lhe wind and the weight of lhe fruits. Toe results for the insect attack showed that cravo tangerine presented 35% of attack, baianinha 27%, natal 24o/o, tangor sabara 20% and rio tangerine 13%. The presence ofthe larvas was not observed in cravo lemon
