摘要
稻纵卷叶螟（Cnaphalocrocis medinalis Guenee）已成为一个令人担忧的主要问题，在印度各地引起了爆发。研究人员对 C. medinalis 的生长、存活、繁殖和死亡率进行了生命表分析，旨在确定其最弱的生命阶段并揭示其种群动态。研究发现，四龄幼虫阶段的存活率最高，卵和一龄幼虫阶段的存活率最低。种群趋势指数为 5.9，表明种群增长显著。
Population Dynamics of the Rice Leaf Folder Cnaphalocrocis medinalis Guenee: A Lifetable Study
The rice leaf folder Cnaphalocrocis medinalis Guenee has become a major concern, causing outbreaks in various parts of India. A lifetable study was conducted to analyze the growth, survival, reproduction, and mortality of C. medinalis, aiming to determine the weakest lifestages and unravel its population dynamics. The study observed the highest survival rate at the fourth-instar larval stage and the lowest during the egg and first-instar larval stages. A population trend index of 5.9 was observed, indicating significant population growth.
