Peptidomics of the Agriculturally Damaging Larval Stage of the Cabbage Root Fly Delia radicum (Diptera: Anthomyiidae)
The larvae of the cabbage root fly induce serious damage to cultivated crops of the family Brassicaceae. We here report the biochemical characterisation of neuropeptides from the central nervous system and neurohemal organs, as well as regulatory peptides from enteroendocrine midgut cells of the cabbage maggot. By LC-MALDI-TOF/TOF and chemical labelling with 4-sulfophenyl isothiocyanate, 38 pep...
متن کاملSeasonal Flight, Optimal Timing and Efficacy of Selected Insecticides for Cabbage Maggot (Delia radicum L., Diptera: Anthomyiidae) Control
In order to describe seasonal flight activity of the cabbage maggot Delia radicum (L.) adults in relation to Julian days (JD), degree-day accumulations (DDA) and precipitation, flight dynamics were followed weekly with the use of yellow sticky traps (YST). Climatic data were collected and DDA were calculated using the lower developmental threshold of 4.3 °C. The efficacy of four insecticides ap...
متن کاملExchange of Inoculum of Beauveria bassiana (Bals.) Vuill. (Hyphomycetes) Between Adult Flies of the Cabbage Maggot Delia radicum L. (Diptera: Anthomyiidae)
Adult cabbage maggots (Delia radicum L.) were exposed to dry conidia of isolates of several hyphomycetous fungi by placing them in a centrifuge tube containing conidia, then releasing them into small screened plastic cages. Mortality was assessed after 48, 120 and 160 h. A Beauveria bassiana isolate (P89 from Musca domestica) caused the highest mortality after 48 h, resulting in 100% mortality ...
متن کاملOviposition Substrate of the Mountain Fly Drosophila nigrosparsa (Diptera: Drosophilidae)
The survival of insect larvae often depends on the mother's choice of oviposition substrate, and thus, this choice is an essential part of an insect species' ecology. Especially species with narrow substrate preferences may suffer from changes in substrate availability triggered by, for example, climate change. Recent climate warming is affecting species directly (e.g., physiology) but also ind...
متن کاملHeterorhabditid Behavior in the Presence of the Cabbage Maggot, Delia radicum, and its Host Plants.
The behavior of Heterorhabditis zealandica Poinar strain T327 was investigated in the presence of the cabbage maggot, Delia radicum L., and plants that are susceptible to D. radicum infestation. Newly formed puparia and freeze-killed third instar larvae were attractive to infective nematodes. Newly harvested infective nematodes did not respond to the puparia, whereas 1-month-old and 2-month-old...
