过去记载橡实象鼻虫的卵产于种子内,幼虫在种子内孵化,老熟幼虫由种子内钻出入土中越冬。根据我们的观察,该虫产卵在壳斗内,我们从1958年8月2日至9月22日在20株试验树上选取种子4,791粒进行解剖,均未发现卵,所发现的卵都是在壳斗内,卵为长圆形,乳白色透明。长1.5毫米左右,宽0.5毫米左右,孵化幼虫后才钻入种子内,因钻入孔很小,故很容易被看成为系成虫头管刺破产卵的痕跡,在幼虫钻入孔处如仔细观察习以看出,有幼虫食后所遗留下来
In the past, the eggs of the weevil weevil were found in the seeds, the larvae hatching in the seeds and the mature larvae overwintering from the seeds into the soil. According to our observation, the worm spawned in the shell hopper. From August 2, 1958 to September 22, 1958, 4,791 seeds of 20 test trees were selected for dissection. None of the eggs were found. All of the eggs found In the shell bucket, the egg is oblong, milky white and transparent. About 1.5 mm long, about 0.5 mm wide, hatched larvae after drilling into the seeds, because drilling into the hole is very small, it is easy to be seen as a line of adult head piercing spawning traces of larvae into the hole such as Careful observation to learn to see, larvae left over after eating
