Abstract

The double-spotted leaf beetle (DLB), Monolepta hieroglyphica (Coleoptera: Chrysomelidae), is a polyphagous pest that causes considerable damage to corn in China. However, there is limited knowledge regarding the influence of host plants on the biology of this beetle. This study assessed the feeding of DLB on three corn tissues and three weed species, as well as the impact of host plants/tissues on DLB fecundity. The Feeding rate of DLB was significantly affected by interaction between host plants/tissues and sex, indicating sex-specific patterns of feeding choice. The feeding levels of DLB adults were affected only by host plants/tissues, following the order: common knotgrass > corn silk > corn leaf > Asian copperleaf > white goosefoot > corn kernel. The fecundity of single female adults fed on common knotgrass was the highest (44.70 ± 11.47 eggs), whereas that fed on corn leaf was the lowest (2.00 ± 0.88 eggs). These results underscore the significance of weeds as alternative DLB hosts in corn agroecosystems, improving our understanding of DLB biology and offering valuable insights for establishing and providing an integrated pest management (IPM) program.

象形叶甲虫对玉米和三种杂草不同组织的取食和繁殖力

双斑叶甲（monoolepta hieroglyphica）是一种多食性害虫，对中国的玉米造成严重危害。然而，关于寄主植物对这种甲虫的生物学影响的知识有限。本研究评估了DLB对3种玉米组织和3种杂草的取食，以及寄主植物/组织对DLB繁殖力的影响。寄主植物/组织与寄主性别之间的交互作用显著影响白蛉的取食率，显示出性别特异性的取食模式。成虫取食水平仅受寄主植物/组织影响，顺序为：红叶>；玉米丝>；玉米叶>；亚洲铜叶>；白鹅脚>；玉米仁。单雌成虫产卵量以红叶结叶最高（44.70±11.47个卵），以玉米叶最低（2.00±0.88个卵）。这些结果强调了杂草作为玉米农业生态系统中DLB替代寄主的重要性，提高了我们对DLB生物学的理解，并为建立和提供综合害虫管理（IPM）计划提供了有价值的见解。

期刊介绍： Arthropod-Plant Interactions is dedicated to publishing high quality original papers and reviews with a broad fundamental or applied focus on ecological, biological, and evolutionary aspects of the interactions between insects and other arthropods with plants. Coverage extends to all aspects of such interactions including chemical, biochemical, genetic, and molecular analysis, as well reporting on multitrophic studies, ecophysiology, and mutualism. Arthropod-Plant Interactions encourages the submission of forum papers that challenge prevailing hypotheses. The journal encourages a diversity of opinion by presenting both invited and unsolicited review papers.
