Abstract

The walnut leaf beetle, Gastrolina depressa, belongs to family Chrysomelidae (Coleoptera), and is one of the major pests of walnut trees. G. depressa eggs were oval and dark orange. The three G. depressa larval instars were gray in color. The larval period was approx. 8.14 days ($24^{\circ}C$, 16L:8D). Adults of both sexes were dark blue, and females were larger than males. Overwintered adults emerged in late April, and laid eggs in clusters on young leaves of the host tree. Mature 3rd instar larvae pupated after a short prepupal period. Adults emerged starting mid-May and entered into diapause shortly afterward.

호두나무잎벌레(Gastrolina depressa)의 알은 타원형이며 진한 오렌지색을 띠었다. 유충은 총 3령기를 거치며, 몸전체에 걸쳐 회색을 띠었다. 유충기간은 약 8.14일이 소요되었다. 성충은 암수 모두 남색이었으며, 암컷이 수컷에 비해 크기가 컸다. 월동한 성충은 4월말에 처음 발생하여, 기주식물의 어린잎에 난괴로 산란하였다. 다자란 3령 유충은 짧은 전용기를 거친 후 번데기가 되었다. 새로운 성충은 5월 중순부터 우화한 후, 바로 휴면에 들어갔다.
