| 摘 要： | 利用扫描电镜和透射电镜对苹毛丽金龟Proagopertha lucidula (Faldermann)雌雄成虫触角嗅感器超微结构特征进行研究。结果表明:嗅感器集中于触角鳃片上，分布在触角鳃片表皮内陷形成的凹腔里，有5种感器，以板状感器为主，以外还有锥状感器、腔状感器、腔锥状感器和毛状感器。板状感器根据盘体形状的不同可分为4种类型，锥状感器根据锥体形状的差异可分为2种类型，腔锥状感器根据形状分为2种类型。嗅感器表皮有微孔和孔道微管。嗅感器内神经元的数目并不一致，1～2个不等。雄虫鳃片嗅感器总数显著多于雌性，是雌虫嗅感器总数1.8倍。其中雄性锥状感器的数目是雌性2倍，雌虫腔锥状感器数量是雄虫的4倍，雄虫板状感器数量是雌虫的2倍，雌雄腔状感器的数目无显著性差异。

| Abstract: | The ultrastructure of olfactory sensilla on the antenna of Proagopertha lucidula (Faldermann) adult was studied using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results showed that the olfactory sensilla concentrated on antennal lamellae and all these sensilla were situated in cuticle or in the sunken cavity formed by antennal cuticle depressions. Five types of olfactory sensilla in lamellae were found. There are mainly sensilla placodea (S. pl) in lamellae of P. lucidula. In addition to S. pl, there are sensilla basiconca (S. ba), sensilla cavitica (S. ca), sensilla coeloconica (S. co) and sensilla trichodea (S. tr). Based on the differences of plate and cone shape, S. pl are further classified into four subtypes, S. ba into two subtypes, and S. co into two subtypes. There are a plenty of pores and pore tubules in the cuticle of olfactory sensillum. The number of neurons in olfactory sensilla is inconsistent, including one olfactory receptor neuron (ORN), or two ORNs. The total number of sensilla in the male is 1.8 times that in the female. The number of S. bal in male is two times that in female, the number of S. co in female is four times that in male, while the number of S. pl in male is two times that in female. There is no significant difference in the number of S. co between male and female. |
