摘要:

通过2年多点广泛和系统的田间调查和观察,结合以往调查结果,确定了草地螟取食和产卵植物种类、方式,阐述了不同地区间、幼虫不同龄期时,草地螟对不同植物种类表现喜好度有差异;且观察到草地螟产卵寄主和取食寄主不完全一致,产卵部位和所占比率随环境温度和湿度不同而有所变化。以上结论进一步阐明了草地螟对寄主植物具有较强的选择性,而这种选择性是草地螟种群生存的需要。由此认为,草地螟是种植业上的重要害虫,调整种植作物种类是草地螟治理的有效措施,适时中耕除草可起到趋利避害作用。

Abstract:

Through extensive and systemic field investigation and observation in multi-points for 2 years, combining with former survey results, the host species and behavior mode of Loxostege sticticalis L.’s ovipositing and feeding have been listed and confirmed. The preference differences on plant species among different regions and larvae instars have been expatiated. It is indicated that the feeding host species are not completely coincident with that of ovipositing. The ovipositing positions and their ratios are also not fixed and would change with environmental temperature and humidity. The presented results have further elucidated the Loxostege sticticalis L.’s preference on host and this is an adaptability for population survival and development. Therefore, the meadow moth deserves one of the most important pest in crop growing, so that adjusting of crop species and timing weeding in cultivation are the efficient control measures.
