| 摘要: |
| 本文讨论了农业上的三种重要害虫(小麦叶蜂 Dolerus tritici Chu 黄麦叶蜂Pachynematus sp 和黄翅菜叶蜂 Athalia rosae japanensis(Rhower))成虫的咀嚼式口器,并对黄翅菜叶蜂的食性进行了描述。通过喂养观察,发现菜叶蜂成虫喜食糖,蜜等液体食物,并可舐食蚜虫蜜露。而不取食固体食物,也无捕食习性。菜叶蜂成虫取食后可延长寿命。作者等对三种叶蜂口器进行比较,并与典型咀嚼式口器的代表直翅类对比,认为:三种叶蜂虽属咀嚼式口器,但在进化过程中,其形态和食性已离直翅类较远,而与过去作者等曾做过的梨茎蜂口器很相似。可以认为叶蜂和茎蜂的口器都可能为咀嚼式向吮吸式进化(蜜蜂的嚼吸式)的一种过渡类型。 |

| A SURVEY ON THE MOUTHPARTS OF ADULT SAWFLIES AND THEIR FEEDING HABITS |

| Abstract: |
| The present study was carried out in 1984 by dissecting the adult mouthparts of three species of sawflies:Dolerus tritici Chu,Pachynema- tus sp.and Athalia rosae japanensis(Rhower),(Hymenoptera:Tenthredin- idae),the last being used for rearing test for the purpose of the obser- vation of feeding habits.It has been proved that Athalia adults feed only on liquid foods,such as sugar water,honey,honeydew of aphids,and never feed on solid food.The mouthparts of the above mentioned three had been compared in deta... |
