红彩瑞猎蝽对亚洲玉米螟幼虫的捕食功能反应
The predation functional response of Rhynocoris fuscipes on Ostrinia furnacalis larvae
摘要
Abstract
[Aim]To study the predation ability of Rhynocoris fuscipes on Ostrinia furnacalis(Asian corn borer)and provide theoret-ical foundation for biological control of O.furnacalis.[Method]Indoor experiments were designed to estimate the predation function-al response,searching effect,and intra-specific interference effect of R.fuscipes in different developmental stages on larvae of O.fur-nacalis at different instars.[Result]The predatory functional response of different stages of R.fuscipes on the 2nd to 4th instar lar-vae of O.furnacalis belongs to the Holling Ⅱ type.For the 2nd instar larvae of O.furnacalis,the predation efficiency and theoretical maximum daily predation of male adults of R.fuscipes were the highest,reaching 144.2 and 232.6 individuals.However,for the 3rd and 4th instar larvae of O.furnacalis,the female adults of R.fuscipes had the highest predation efficiency,reaching 49.1 and 67.6 individuals,21.7 and 39.2 individuals per day,respectively.The searching effect decreased with the increase of the larval density of O.furnacalis.At the same developmental stage and density,the overall trend was female adults>male adults>5th instar nymphs>4th instar nymphs>3rd instar nymphs.The Watt model was used to fit the interference effect.The results showed that with the increase of the density of R.fuscipes,the interference effect increased,and the daily predation number of O.furnacalis larvae by single predator decreased.The female adults had the strongest self-interference effect,with a competition parameter of 0.236,while the 5th instar nymphs had the weakest self-interference effect,with a competition parameter of 0.187.[Conclusion]R.fuscipes exhibits a strong predatory effect on the 2nd to 4th instar larvae of O.furnacalis,demonstrating excellent potential for biological control.关键词
