Investigations on the Biology of Hazelnut Beetle, Balaninus nucum L. (Coleoptera: Curculionidae) and its Damage to Hazelnut

Kazim Sezen, Omer Erturk and Zihni Demirbag

Abstract:
The hazelnut beetle (Coleoptera: Curculionidae, Balaninus nucum L.) found in many regions of the world. In order to logical control of this pest, it is necessary to determine the biology and form of its damage. In this study, the biology damage caused by B. nucum were investigated on larvae and adults collected from the coast of Trabzon province in period of 1996-1998. In the end of the present investigation, the wing (10±0.8 mm for females, 9.3 ± 0.3 mm for males) and rostrum length 0.3 ± 0.4 mm for females. 3.8 ± 0.2 mm for males) of the adults, sex ratio (1/1), the dimensions of eggs (0.795 ± 0.14, 0.525 ± 0.11 mm), and instars of larvae (512.5 ± 15; 800 ± 8; 1005 ± 10; and 1295 ± 6 μm in diameter) were detarmined. Also, the appearance of the damage caused by the insect was observed.
