Abstract

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae), is one of the world’s most destructive fruit pests. Ceratitis capitata pupates in the soil, making it a target of many soilborne pathogens like entomopathogenic nematodes (EPNs). Entomopathogenic nematodes are highly lethal to many important pests, safe to non-target organisms and they might be good alternatives for control of C. capitata . In this study, the efficacy of four local EPN species; Steinernema affine Bovien, 1937, Steinernema carpocapsae Weiser, 1955, Steinernema feltiae Filipjev, 1934 (Rhabditida: Steinernematidae) and Heterorhabditis bacteriophora Poinar, 1976 (Rhabditida: Heterorhabditidae) against the third instar larvae and pupae of C. capitata were evaluated. The study was conducted in 2019-2020 both in the laboratory (in plastic cups) and in a climate room (in wooden cages with plastic pots) at doses of 100 and 200 IJs/larva-pupa and 7,650 and 15,300 IJs/pot, respectively. Larvae of C. capitata were found more susceptible to EPNs than pupae in the study. Steinernema feltiae isolate 113 and H. bacteriophora isolate 12 showed the highest efficacy while S. affine isolate 47 showed the least efficacy against the pest larvae and pupae. Suppression of C. capitata population by EPNs indicates that these EPNs can be considered as a biological control agent potentially useful for the control of this pest. After further support by field studies, these two local EPN isolates could be used as promising eco-friendly biological agents against C. capitata.

利用当地昆虫病原线虫控制地中海果蝇Ceratis capita(Wiedemann,1824)(Diptera:Tephritidae)
地中海果蝇Ceratitiscapita(Wiedemann,1824)(直翅目:地蝇科)是世界上最具破坏性的水果害虫之一。头Ceratis capita在土壤中化蛹,使其成为许多土传病原体的靶标,如昆虫病原线虫(EPNs)。昆虫病原线虫对许多重要害虫具有高度致死性,对非靶标生物是安全的,它们可能是控制头盘线虫的良好替代品。在本研究中,四种当地EPN的药效;评估了Steinerma affine Bovien,1937,Steinerma-carpcapsae Weiser,1955,Steinernama feltiae Filijev,1934(Rhabditida:Steinermatidae)和Heterrhabdititis bacterophora Poinar,1976(Rhabtitida:Heterrhabiditidae)对头盘线虫三龄幼虫和蛹的抗性。这项研究于2019-2020年在实验室(塑料杯中)和气候室(带塑料罐的木笼中)进行,剂量分别为100和200 IJs/幼虫蛹和7650和15300 IJs/罐。在这项研究中发现,头状C.capita的幼虫比蛹更容易感染EPNs。Steinerma feltiae分离株113和H.bacteriophora分离株12对害虫幼虫和蛹的效力最高,而S.affine分离株47对害虫幼虫的效力最低。EPN对C.capita种群的抑制表明,这些EPN可以被认为是一种可能对控制这种害虫有用的生物控制剂。经过实地研究的进一步支持,这两个地方EPN分离株可以作为一种很有前途的生态友好的生物制剂来对抗头状锥虫。

期刊介绍: The Turkish Journal of Entomology is a quarterly journal which has been published by Entomological Society. Turkish Journal of Entomology publishes original research articles in the fields of entomology and agricultural zoology in English. Authors whose native language is not English should have their paper edited professionally prior to submission. Before preparing the typescript for submission, examine the format of manuscripts already published in Turkish Journal of Entomology. According to TJE rules, biological observations made in one location in only one-year, short notes in which the first record of a single species in Turkey is announced, and research which is older than five years will not be accepted for publication unless it forms part of a longitudinal study.
