在生物入侵过程中，由于害虫逃离了原产地天敌的控制，常常会发生害虫暴发。但有些天敌可以随害虫迁移，有效抑制其危害。温度变化能否缩短或增强伴生天敌的生殖发育期是其能否有效随害虫迁移的重要决定因素。班巴瓦依小蜂是重要入侵害虫扶桑绵粉蚧的主要伴生寄生蜂。为了解温度变化对该蜂生殖系统发育的影响，比较了不同温度下该蜂的发育、形态和生殖力的差异。结果表明，高温能显著缩短蛹的发育历期，增加后胫长度，促进性腺发育。研究结果表明，适度高温有利于该蜂的繁殖和发育，可能与雌蜂后代多有关。这是首次报道高温对蛹的发育、形态和生殖力的影响。班巴瓦雷。高温对昆虫，包括生物入侵者及其伴随的天敌的发育、形态和生殖力特征的影响是清楚的。扶桑绵粉蚧（Phenacoccus solenopsis）是一种世界性的入侵害虫。斑巴瓦依小蜂（Aenasius bambawalei，=Aenasius arizonensis Girault）是粉蚧的主要伴生寄生蜂。我们前期的研究表明，温度变化引起了中华绒螯蟹雌性后代比例的增加。班巴瓦雷。然而，这种增长是否是由于缩短或增强的生殖系统的发育期的A。班巴瓦雷仍然下落不明。比较了蛹的发育、雌成虫的后胫和产卵量。本研究旨在探讨不同温度下红腹叶蝉的生长发育及形态变化，并进一步了解红腹叶蝉作为伴生天敌的潜力。结果表明，在高温（36 °C）条件下，蛹的发育历期延长。bambawalei仅为对照的0.80倍，后胫骨长度为对照的1.16倍。此外，高温还能加快性腺的发育速度，增加卵子和精子的数量。结果表明，加温缩短了蛹的发育历期，改变了雌成虫后胫长度，促进了雌成虫的产卵。班巴瓦雷。这些发现将有助于了解伴生天敌的适应机制。此外，这些发现将有助于利用这种行为来有效地控制入侵害虫。
During biological invasions, insect pest outbreaks often occur because they escape the control of natural enemies from their place of origin. However, some natural enemies can migrate with pests to effectively inhibit their damage. Whether temperature changes can shorten or enhance the reproductive developmental period of accompanying natural enemies is an important determinant of whether they can effectively migrate with pests. Aenasius bambawalei is a predominant accompanying parasitoid of the important invasive pest Phenacoccus solenopsis. To understand the effect of temperature changes on the development of the reproductive systems of this parasitoid, we compared differences in its development, morphology, and fecundity under different temperatures. The results showed that high temperature could significantly shorten the pupal developmental duration, increase the length of the hind tibia, and accelerate gonad development. Our results indicated that moderately high temperature was conducive to the reproduction and development of the parasitoid and may be related to the more females offspring. This is the first report of the impact of high temperature on the pupal development, morphology, and fecundity of A. bambawalei. The effects of high temperature on the developmental, morphological, and fecundity characteristics of insects, including biological invaders and their accompanying natural enemies, are clear. Phenacoccus solenopsis (Homoptera: Pseudococcidae) is an aggressive invasive insect pest worldwide. Aenasius bambawalei (=Aenasius arizonensis Girault) (Hymenoptera: Encyrtidae) is a predominant accompanying parasitoid of this mealybug. Our previous studies showed that temperature change induced an increase in the female offspring ratio of A. bambawalei. However, whether this increase is the result of a shortened or enhanced development period of the reproductive systems of A. bambawalei remains unknown. Here, we compared the pupal development, hind tibia of female adults, and fecundity of A. bambawalei under different temperatures to clarify the development and morphological changes induced by high temperature and to better understand its potential as an accompanying natural enemy. Our results showed that, at a high temperature (36 °C), the pupal developmental duration of A. bambawalei was only 0.80 times that of the control, and the length of the hind tibia was 1.16 times that of the control. Moreover, high temperature accelerated the developmental rate of gonads and increased the numbers of eggs and sperm. These results indicated that experimental warming shortened the pupal developmental duration, altered the hind tibia length of female adults, and facilitated the fecundity of A. bambawalei. These findings will help to understand the adaptation mechanisms of accompanying natural enemies. Furthermore, these findings will help to make use of this behavior to effectively control invasive pests.
