Courtship and mating behaviour of the Mediterranean corn borer, Sesamia nonagrioides (Lepidoptera: Noctuidae)
The behavioural sequence of courtship and mating of Sesamia nonagrioides Lefèbvre males and females in laboratory cages is described. The attractant capacity of both sexes was studied by tethering males or females. The courtship and mating sequence of tethered females was the same as untethered ones, but tethered males were absolutely inactive. Age (1 day versus 2 days) did not affect the matin...
متن کاملHost location behaviour of gravid females in the Mediterranean corn borer Sesamia nonagrioides: external morphology of antennae and ovipositor sensilla
The behaviour of gravid females of Sesamia nonagrioides (Lefebvre) during host plant location in a wind tunnel is described using an ethogram and compared with unmated females, males and gravid females deprived of antennae. The sequence of behaviours exhibited by the majority of the intact gravid females began with a resting period followed by the unfolding of the antennae towards the plant plu...
متن کاملToxicity and mode of action of Bacillus thuringiensis Cry proteins in the Mediterranean corn borer, Sesamia nonagrioides (Lefebvre).
Sesamia nonagrioides is one of the most damaging pests of corn in Spain and other Mediterranean countries. Bt corn expressing the Bacillus thuringiensis Cry1Ab toxin is being grown on about 58,000 ha in Spain. Here we studied the mode of action of this Cry protein on S. nonagrioides (binding to specific receptors, stability of binding, and pore formation) and the modes of action of other Cry pr...
متن کاملSystematics and biology of Cotesia typhae sp. n. (Hymenoptera, Braconidae, Microgastrinae), a potential biological control agent against the noctuid Mediterranean corn borer, Sesamia nonagrioides
Many parasitoid species are subjected to strong selective pressures from their host, and their adaptive response may result in the formation of genetically differentiated populations, called host races. When environmental factors and reproduction traits prevent gene flow, host races become distinct species. Such a process has recently been documented within the Cotesia flavipes species complex,...
متن کاملBacteria Isolated from the Stem Borer Sesamia Nonagrioides (lepidoptera: Noctuidae) in Iran
Sesamia nonagrioides (Lef.) is a major insect pest of sugarcane in southwestern Iran. It also damages maize and rice in this area. Using bacterial pathogens of insects as a biological control agent in an IPM program could be advantageous. In this study, the bacterial flora of S. nonagrioides were investigated in dead larvae with appearance of some bacterial disease. Samples were collected from ...
