棉蚜（Aphis gossypii格洛弗）是温室作物的主要害虫之一。蚜虫寄生蜂Aphidius colemani Viereck和Aphidius matricariae（Haliday）（膜翅目：茧蜂科：蚜亚科）是防治黄蚜的良好药剂。棉花属在地中海地区，这些拟寄生虫目前可以在高温条件下释放。然而，关于它们的行为随温度变化的研究结果很少。本文分析了20 ~ 32 A ℃恒温条件下，对甘蓝蚜和苜蓿蚜的飞行、行走和产卵能力的影响。我们的研究结果表明，飞行能力明显受到温度的影响。最佳飞行温度为20和25摄氏度。colemani和A. matricariae，分别。对于这两个物种，我们观察到在较高的温度下行走能力增加，但生殖潜力下降。此外，无论在什么温度下，A. colemani比A.母菊这些结果表明A. colemani比A. matricariae的生物防治。地中海环境中的棉蚜。
The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae) is one of the major pests of many greenhouse crops. The aphid parasitoids, Aphidius colemani Viereck and Aphidius matricariae (Haliday) (Hymenoptera: Braconidae: Aphidiinae) have been considered good agents for the biological control of A. gossypii. In Mediterranean area, these parasitoids can currently be released under elevated temperature conditions. However, few findings on their behavior changes with temperature are available. In this study, we analyze the consequence of constant temperatures ranging from 20 to 32 A degrees C on the flight, walking and oviposition capacities of Aphidius colemani and Aphidius matricariae. Our results revealed that flight capacity is clearly influenced by temperature. The optimal temperatures for flying are 20 and 25 A degrees C for A. colemani and A. matricariae, respectively. For both species, we observed an increase in the walking capacity but a decrease in the reproductive potential at higher temperatures. Furthermore, regardless of the tested temperature, the mummy production rate was always higher in A. colemani than in A. matricariae. These results indicate that A. colemani is more suitable than A. matricariae for the biological control of A. gossypii in Mediterranean environments.
