Abstract

ABSTRACT The olive fruit fly, Bactrocera oleae, is one of the main pests of this crop and its control requires the development of methods environmentally safer than those used mostly nowadays, being biological control a possible alternative. Accordingly, the capacity of parasitisation and the biological parameters of Muscidifurax raptorellus, a generalist parasitoid of dipteran pupae, were evaluated on B. oleae at 25°C, 80% RH and a 16:08 h light/dark photoperiod. In a development assay, the rates of parasitism ranged 60% to 72% and the duration of the preimaginal period was between 17.0 and 18.5 days. The total mean number of adult wasps produced per pair in a reproduction assay was 50.7, with a mean daily production of 7 individuals and a mean rate of parasitism of 32.6%. The moment of maximum offspring production was estimated at 2.6 days after the beginning of the oviposition. The intrinsic rate of natural increase of M. raptorellus on B. oleae was 0.147, what determines a population doubling time of 4.7 days. The functional response was type II and the maximum attack rate in 24 h was 19.6 pupae. At host densities ranging 20–80 pupae per female, the number of adult wasps produced was around 20–22. The results obtained show the potential of M. raptorellus to be used for the biological control of B. oleae.

油橄榄主要害虫油小蝇(双翅目:油小蝇科)对油小蝇的生物学参数研究

橄榄果蝇(Bactrocera oleae)是橄榄作物的主要害虫之一，其防治需要开发比目前常用的方法更环保、更安全的方法，是一种可能的替代方法。在25°C、80% RH、16:08 h光照条件下，测定了双翅目蝇蛹的一般寄生蜂raptorellus对油叶白蝇的寄生能力和生物学参数。在发育试验中，寄生率为60% ~ 72%，预想象期为17.0 ~ 18.5天。每对繁殖试验平均产生的成虫总数为50.7只，平均每天产生7只，平均寄生率为32.6%。估计产卵开始后2.6天为最大产仔时刻。raptorellus对油叶小蠊的内在自然增殖率为0.147，种群倍增时间为4.7 d。功能反应为ⅱ型，24 h内最大侵染率为19.6只。当寄主密度为每只雌蜂20-80只蛹时，成虫数量约为20-22只。结果表明，raptorellus具有应用于油叶小蠊生物防治的潜力。
