Comparative study on life cycle of Eudocima materna and Eudocima phalonia (Lepidoptera: Noctuidae) Serious pest on Pomegranate

Abstract: This comparative study investigates the life cycles of two significant noctuid moth pests, Eudocima materna and Eudocima phalonia, which have notable impacts on pomegranate cultivation. Both species are prevalent in tropical regions and are known for their destructive feeding habits that lead to reduced crop yields and compromised fruit quality. The study was conducted in controlled environmental settings to elucidate the similarities and differences in their developmental stages, including egg, larval, pupal, and adult phases. Findings indicate that E. materna completes its life cycle in approximately 40-45 days, while E. phalonia takes about 50-55 days, with variances in larval instar durations and feeding behaviors. The research highlights distinct morphological characteristics and behavioral patterns across life stages, suggesting that environmental factors such as temperature and humidity significantly influence their development. This study fills a critical gap in pest management literature by providing a comparative analysis that can inform effective strategies for mitigating the agricultural impact of these pests on pomegranate crops.
