摘要
【目的】为明确黄翅绢野螟Diaphania caesalis在不同植物上的生长发育、存活及繁殖特性,探讨其在不同植物上的生长发育和繁殖适合度。【方法】采用室内饲养观察和组建年龄-龄期两性生命表的方法,测定取食波罗蜜Artocarpus heterophyllus、榴莲蜜A.integer、面包树A.altilis和大果榕Ficus auriculata 4种植物叶片的黄翅绢野螟的生活史参数。【结果】取食这4种植物叶片的黄翅绢野螟均能完成完整的世代发育。取食波罗蜜叶片的黄翅绢野螟幼虫存活率、成虫单雌产卵量显著高于取食其他3种植物叶片的,取食波罗蜜叶片的黄翅绢野螟的内禀增长率r和净增殖率R0分别为0.100 d^(-1)和38.72,均高于取食榴莲蜜叶片的(分别为0.056 d^(-1)和8.52)、取食面包树叶片的(分别为0.054 d^(-1)和8.14)、取食大果榕叶片的(分别为0.074 d^(-1)和14.82)。【结论】与取食其他3种植物叶片的黄翅绢野螟相比,取食波罗蜜叶片的黄翅绢野螟具有更高的种群增长能力。黄翅绢野螟取食4种植物均能满足其生长发育和繁殖的需求,但对嗜食寄主植物波罗蜜的适合度最高,对大果榕也表现出一定的适合度,对榴莲蜜和面包树的适合度相对较低。
【Aim】To clarify the growth,development,survival and reproduction characteristics of the jackfruit pest Diaphania caesalis,on different plants and to ascertain its growth and development,and reproductive fitness on different plants.【Methods】The life history parameters of D.caesalis reared on leaves of four plants including Artocarpus heterophyllus,A.integer,A.altilis,and Ficus auriculata were determined by indoor breeding observation and constructing age-stage,two-sex life table.【Results】D.caesalis could complete its lifecycle when reared on leaves of these four plants.The larval survival rate and number of eggs laid per female adult of D.caesalis reared on A.heterophyllus leaves were significantly higher than those on leaves of the other three plants.The intrinsic rate of increase(r)and net reproductive rate(R0)of D.caesalis reared on A.heterophyllus leaves were 0.100 d^(-1)and 38.72,respectively,being higher than those reared on leaves of A.integer(0.056 d^(-1) and 8.52,respectively),A.altilis(0.054 d^(-1) and 8.14,respectively),and F.auriculata(0.074 d^(-1) and 14.82,respectively).【Conclusion】D.caesalis reared on leaves of A.heterophyllus has higher population growth ability than those reared on leaves of the other three plants.Reared on these four plants,D.caesalis can grow and reproduce normally,but the fitness of D.caesalis reared on its favorite host plant A.heterophyllus is the highest.D.caesalis also shows certain fitness to F.auriculata,and relatively low fitness to A.integer and A.altilis.
