Summary Excerpt Details

The life cycle of Helicoverpa armigera, commonly known as the cotton bollworm, is a significant concern for the cotton industry in Australia. This paper explores the various stages of the bollworm's life cycle, including egg deposition, larval feeding, pupation, and adult emergence. The impacts of Helicoverpa armigera on the cotton industry are examined, highlighting the substantial economic losses incurred due to yield reduction and increased pesticide use. The paper further discusses effective management strategies, such as integrated pest management techniques, genetically modified cotton varieties, and targeted pesticide application. Implementing a comprehensive approach to control Helicoverpa armigera can help mitigate its detrimental effects on the cotton industry in Australia.
