Abstract
The interaction between thermal stress and chemical insecticides in agricultural pests has become more common owing to the global warming and human activities. Although research has shown the interaction of constant temperature or single thermal stress with insecticides, the ecological effects of sublethal thermal stress and low-dose insecticide interaction, which are more applicate to field conditions, are limited. Therefore, this study investigates the interaction of sublethal thermal stress (TS) (34 °C/180 min, 36 °C/30 min, and 38 °C/10 min) and low-dose imidacloprid (IM) applications in the maternal and offspring phenotype of the important grain aphid, Sitobion avenae (Fabricius) (Hemiptera: Aphididae). In the F0 generation, single TS significantly reduced the longevity, fecundity, survivorship, and population parameters of S. avenae, and the interaction between TS and IM (TS-IM) had a significant negative effect on the intrinsic rate of increase in the order 34 °C/180 min + IM > 36 °C/30 min + IM > 38 °C/10 min + IM. In the F1 generation, the development duration of nymph was increased and the intrinsic rate of increase was reduced after F0 underwent TS. However, the intrinsic rate of increase of F1 generation showed the greatest decrease under 38 °C/10 min + IM, and the lowest decrease under 34 °C/180 min + IM. The results of this study reveal the significance of evaluating together different abiotic factors, such as the interaction between thermal stress and insecticides, in the risk assessment of climate change, emphasizing the importance of the combination of different stresses in pest control.
由于全球变暖和人类活动,农业害虫的热胁迫与化学杀虫剂之间的相互作用变得越来越普遍。虽然研究表明恒温或单一热胁迫与杀虫剂之间存在相互作用,但更适用于田间条件的亚致死热胁迫和低剂量杀虫剂相互作用的生态效应却很有限。因此,本研究探讨了亚致死热胁迫(TS)(34 °C/180分钟、36 °C/30分钟和38 °C/10分钟)和低剂量吡虫啉(IM)对重要谷粒蚜虫Sitobion avenae (Fabricius) (半翅目:蚜科)母本和子代表型的交互作用。在F0代中,单一TS显著降低了S. avenae的寿命、繁殖力、存活率和种群参数,TS与IM的交互作用(TS-IM)对其内在增长率有显著的负面影响,依次为34 °C/180 min + IM > 36 °C/30 min + IM > 38 °C/10 min + IM。在 F1 代中,F0 经过 TS 后,若虫的发育时间延长,内在增长率降低。然而,F1 代的内在增长率在 38 °C/10 min + IM 条件下下降幅度最大,在 34 °C/180 min + IM 条件下下降幅度最小。该研究结果揭示了在气候变化风险评估中综合评估不同非生物因素(如热胁迫与杀虫剂之间的相互作用)的意义,强调了在害虫控制中综合使用不同胁迫的重要性。
期刊介绍:
Its scope covers all aspects of basic and applied research dealing with insects and more broadly with arthropods inhabiting wild, agricultural and/or urban habitats. The journal also considers research integrating various disciplines and issues within the broad field of entomology and ecology.
Entomologia Generalis publishes high quality research articles on advances in knowledge on the ecology and biology of arthropods, as well as on their importance for key ecosystems services, e.g. as biological control and pollination. The journal devotes special attention to contributions providing significant advances (i) on the fundamental knowledge and on sustainable control strategies of arthropod pests (including of stored products) and vectors of diseases, (ii) on the biology and ecology of beneficial arthropods, (iii) on the spread and impact of invasive pests, and (iv) on potential side effects of pest management methods.
Entomologia Generalis welcomes review articles on significant developments in the field of entomology. These are usually invited by the editorial board, but proposals may be sent to the Editor-in-Chief for preliminary assessment by the editorial board before formal submission to the journal. The journal also considers comments on papers published in Entomologia Generalis, as well as short notes on topics that are of broader interest.
