Host-related fitness trade-offs in a presumed generalist parasitoid, Diaeretiella rapae (Hymenoptera: Aphidiidae)
1. Host ranges of parasitoid wasps are mediated by behavioural responses to hosts and their environment (infectivity), and development in hosts (virulence). Determinants of host range were measured in Diaeretiella rapae (Hymenoptera: Aphidiidae), which has been described as a generalist that attacks more than 60 species. 2. In northern Colorado, this wasp mainly attacks two hosts: cabbage aphid...
متن کاملHost age preference of Microplitis mediator (Hymenoptera: Braconidae), an endoparasitoid of Mythimna separata (Lepidoptera: Noctuidae)
Microplitis mediator (Haliday) is a solitary endoparasitoid of larvae of the cotton bollworm, Helicoverpa armigera (Hübner) and the oriental armyworm, Mythimna = Leucania separata (Walker). The preference and suitability of different instars of M. separata for M. mediator were determined under laboratory conditions at a constant temperature of 26 ± 1 C, 65 ± 5% RH and L14:D10 photoperiod. The s...
متن کاملIdentification and validation of reference genes for gene expression analysis in Aphidius gifuensis (Hymenoptera: Aphidiidae)
Reference genes have been utilized in estimating gene expression levels using quantitative reverse transcriptase-quantitative polymerase chain reaction (qRT-PCR) analysis. Aphidius gifuensis Ashmaed is one of the most widely used biological control agents for aphids. The biological properties of this species have been studied in detail, and current investigations are focused on elucidating the ...
متن کاملFunctional response and mutual interference of Diaeretiella rapae (Hymenoptera: Aphidiidae) on Brevicoryne brassicae (Homoptera: Aphididae)
Functional response and mutual interference are the most important behavioural characteristics that reveal different aspects of host–parasitoid interactions. In this study, functional response and mutual interference of the parasitoid wasp, Diaeretiella rapae (M’Intosh) attacking the cabbage aphid, Brevicoryne brassicae (Linnaeus) were investigated. Logistic regression was used to distinguish t...
متن کاملThe effect of choice and no-choice access on host (Aphis fabae) instars preference, in different ages and sizes of Lysiphlebus fabarum (Hymenoptera: Braconidae: Aphidiinae)
چگونگی تاثیر پارازیتوئیدها روی تغییرات جمعیت میزبان، تحت تاثیر ترجیح سن پورگی میزبان قرار دارد. این طرح ترجیح ثابت نبوده و همراه با فراوانی نسبی و میزان در دسترس بودن، تفاوت در شدت رفتارهای دفاعی و همچنین اثرات مادری زنبور کاوشگر تغییر می‌یابد. در این مطالعه ترجیح سن پورگی میزبان در استرین ماده‌زای زنبور پارازیتوئید Lysiphlebus fabarum (Marshall) در ارتباط با کارایی نتاج روی سنین اول، دوم و چها...
