利用雄蜂幼虫移入王台内生产王浆 ,可以取得与利用工蜂幼虫生产同等重量的王浆。为了进一步研究雄蜂幼虫 (即未受精卵幼虫 )在王台内能否培育出雄蜂成蜂 ,特请无锡市养蜂家时集成作了实验。实验日期 :2 0 0 3年 4月 8日。实验群群势 :1 4框 ,双王群。环境 :是油菜花大流蜜 ,最好的育王时期 ,气候温和。共移雄蜂幼虫 40只 ,移入 2条浆条。每条 2 0个台基。为了作好对照 ,在同一个浆框上 ,上面 2条浆条是雄蜂幼虫 ,下面 1条浆条是 2 0只工蜂幼虫。。开始 ,哺育工蜂全部接受幼虫造台。到 4月 1 4日工蜂王台都全部正常封盖。雄蜂王台也封盖 ,但… 相似文献

正第一阶段是工蜂产卵初期。这一阶段工蜂产卵群对工蜂幼虫和工产雄蜂幼虫哺育一视同仁,调入幼虫脾能得到正常饲喂。介王容易。第二阶段是工蜂产卵中期。这一阶段小雄蜂封盖子脾成片,他群调入幼虫脾除被用来改造王台外,其余幼虫会被清除。介王困难。第三阶段是工蜂产卵后期。这一阶段小雄蜂出房,小雄蜂幼虫稀少,他群调入幼虫脾,除用来改造急造王台外,剩余幼虫继续清理。介王较易。 相似文献

在卡蜂的一个品系中发现了白眼突变的雄蜂。用产白眼雄蜂的蜂王作母本,培育处女王,用本群白眼雄蜂的精液给该处女王进行人工授精。该人工授精王产的雄蜂和工蜂各有50%为白眼突变个体。用该人工授精王产的二倍体幼虫培育出了白眼处女王。白眼处女王产的雄蜂全部为白眼雄蜂。白眼雄蜂和白眼工蜂似乎没有视力,出巢后不能返回蜂巢。 相似文献

本文对浙农大1号意蜂(E_a)和本地意蜂(E_b)的工蜂、蜂王、雄蜂的发育时龄(从卵到成虫羽化)进行了研究。其结果是:E_a和E_b的平均发育时龄,工蜂分别为504.7和506.8小时,蜂王分别为387.5和395.5小时,雄蜂分别为581.5和585.6小时。E_a和E_b三型蜂的发育时龄均存有差异,E_a的工蜂、蜂王、雄蜂发育时龄分别比E_b缩短2.1、8.0和4.1小时。此外,还发现受精卵的胚胎发育比未受精卵快。 相似文献

试验测定和分析了Bombus pyrosoma、B.terrestris、B.patagiatus和B.lucorum 4种熊蜂蜂王初生重和三型蜂的喙长,结果表明:4种熊蜂的蜂王喙长与初生重均存在高度正相关性,各回归方程的相关系数均达极显著.同种熊蜂三型蜂间,蜂王喙长明显长于工蜂和雄蜂的喙长,除B.pyrosoma工蜂喙长明显长于雄蜂的喙长外,其他三个熊蜂种的工蜂与雄蜂喙长相等.同型蜂4种熊蜂间,B.pyrosoma和B.terrestris蜂王初生重和工蜂喙长分别相等,蜂王喙长和雄蜂喙长均不等,B.patagiatus和B.lucorum的蜂王初生重和三型蜂喙长分别相等,但前两者蜂王初生重明显重于后两者的,三型蜂喙长分别长于后两者的. 相似文献

以中华蜜蜂为研究材料,用人工转卵的方法,系统研究了中华蜜蜂蜂群间工蜂对卵及幼虫的辨认与监督行为特性。结果表明,中华蜜蜂工蜂对群间的受精卵和雌性幼虫辨认与监督效果差异不显著。说明中华蜜蜂工蜂对群间的受精卵和雌性幼虫不存在辨认与工蜂监督。 相似文献

An 8 wk old Scottish terrier was evaluated for a 2×2 cm mass located directly adjacent to the lateral canthus of the right eye. Examination revealed a well-developed Cuterebra larva at the lateral aspect of the orbital cavity, anchored at the lateral canthus. The larva was manually removed under general anesthesia, and the eyelid margin was repaired. Systemic and topical antibiotics along with systemic anti-inflammatory treatment were instituted. The lesion healed completely, revealing a normal functional right eye 10 days after removal of the Cuterebra larva. Careful manual removal of the larva is recommended along with correction of any resultant conformational defects. The remaining cavity can be left to heal; however, antibiotic therapy is recommended. 相似文献

The mite Varroa jacobsoni, an ectoparasite of the honey bee, was imported to Tunisia probably in 1976. Afterwards, this parasitosis caused severe losses of colonies for several years. The continued examination of the level of infestation in colonies of a "GTZ" project stated a steady number of mites since 1980. Only in a few colonies, the infestation was above the limit of damage. Though the colonies in North West Tunisia did not receive any treatment since 1986 there was no increase of infestation. In order to investigate the reason for this the mites' ability of reproduction was examined during two following years. The portion of infertile female mites in the worker brood in most of the colonies was with 50% considerably higher than in Europe. In Brazil, the adaptation between host and mite produced similar low reproduction rates. As, however, in Tunisia the portion of infertile females in the drone brood of the individual colonies corresponded to the one in the worker brood climatic conditions are supposed to be responsible. 相似文献
