近几年来白星花金龟[Potosis(Lioco la)brevitavis(Lewis)在我市的一些棉区不断发生,为害棉铃也渐趋严重。由于白星花金龟在我省为害棉铃的情况过去并未有过报道,不易引起人们的注意,因此在某些地方或某些田块为害程度也较重。白星花金龟是以成虫啮食棉铃,1987年8月10日,20日、9月1日我们分别在九江县马回岭乡附近的几个棉田定点调查均发现有白星花金龟的为害,其中以农校棉田为害较重,有虫率较高,亩虫数多者近300头,少的也有200余头左右。

As the white-bellied flower beetle harm cotton boll in our province has not been reported in the past, difficult to attract the attention of people, so in some places or some plots of damage is also more serious.
