Host 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 کاملNeotropical species of Meteorus Haliday (Hymenoptera: Braconidae: Meteorinae) parasitizing Arctiinae (Lepidoptera: Noctuoidea: Erebidae).
Three new species of Meteorus parasitoids of Arctiinae are described: Meteorus anuae n. sp., M. juliae n. sp. and M. mirandae n. sp. The first biological record for M. cecavorum Aguirre & Shaw as well as its cocoon description is reported. A comprehensive key for the Neotropical Meteorus attacking Arctiinae is provided. A total of nine Meteorus species have been reared from Arctiinae in the Neo...
متن کاملThe rearing of the gregarious koinobiont endoparasitoid Microplitis tristis (Hymenoptera: Braconidae) on its natural host Hadena bicruris (Lepidoptera: Noctuidae)
We describe a method for the rearing of the oligophagous herbivore Hadena bicruris, and its gregarious koinobiont endoparasitoid Microplitis tristis under laboratory conditions. With flowers from the host food plant Silene latifolia available, female moths lay on average 414 eggs during their lifetime, starting at day 3 after eggression and with a peak number per night on day 8. Caterpillars ca...
متن کاملDefensive behaviors of the Oriental armyworm Mythimna separata in response to different parasitoid species (Hymenoptera: Braconidae)
This study examined defensive behaviors of Mythimna separata (Lepidoptera: Noctuidae) larvae varying in body size in response to two parasitoids varying in oviposition behavior; Microplitis mediator females sting the host with the ovipositor after climbing onto it while Meteorus pulchricornis females make the sting by standing at a close distance from the host. Mythimna separata larvae exhibite...
متن کاملField Release of the Parasitoid Microplitis mediator (Hymenoptera: Braconidae) for Control of Helicoverpa armigera (Lepidoptera: Noctuidae) in Cotton Fields in Northwestern China’s Xinjiang Province
Field experiments and surveyswere conducted in 2003 and2004 to evaluate theefÞcacy of using the parasitoidMicroplitis mediator (Haliday) to control populations of Helicoverpa armigera (Hübner) in cotton Þelds in Northwestern ChinaÕs Xinjiang Province. The population levels of the second generation of H. armigera in southern Xinjiang in 2003 and 2004 were 20Ð60% above the economic threshold of t...
