Life Cycle and Behavior

The life cycle of the sunflower beetle is generally characterized by a single generation per year in many regions, such as ManitobaSunflower Entomology - USDA ARS Adults overwinter in the soil and emerge in May, precisely when the first available sunflower foliage appearsSunflower Beetle - Zygogramma exclamationis (Fabricius) Mating occurs shortly after emergence, followed by egg-layingSunflower Beetle The sunflower beetle larvae, upon hatching, immediately begin to feed voraciously on the foliageSunflower Beetle| Sunflowers | Crop Pests | Insect Information | Extension | Entomology | Kansas State University. Both adult and larval stages of the sunflower beetle are known to consume sunflower leaves, with larvae often causing more extensive damage due to their continuous feedingSunflower Beetle - Zygogramma exclamationis (Fabricius) After completing their larval development, they pupate in the soilSunflower Entomology - USDA ARS The cuticular hydrocarbons on adults, nymphs, and eggs of the sunflower beetle have been a subject of scientific study, contributing to our understanding of their biological makeup作者：CE Rogers·1977·被引用次数：27—ThesunflowerbeetIe, Zygogramma exclamationis.
