As parasitoids upon solitary bees and wasps and their nest cohabitants, Melittobia have an intricate life history that involves both female cooperation and variably expressed male siblicidal conflict. Inter- and intrasexual dimorphism includes blind, flightless males and (probably nutritionally determined) short- and long-winged females. Thought to be… (More)
The distribution of quinine-stimulated Fos-like immunoreactivity (FLI) in several subdivisions of the parabrachial nucleus (PBN) known to be responsive to gustatory stimulation was examined in rats in which the chorda tympani nerve (CT) and/or glossopharyngeal nerve (GL) was transected (Experiment 1) and in rats in which the GL was transected with… (More)
The first confirmed record of Psorophora ciliata from Maine was made at South Berwick, ME, from a carbon dioxide-baited light trap collection on July 25, 2006. Included are collection site data and species bionomics.
To disperse after mating, female Melittobia digitata Dahms (Hymenoptera: Eulophidae) tunnel through the walls of their host’s nest. We found that M. digitata use chemical and structural cues to identify locations for chewing exit holes. An experimental combination of milked venom and artificial pits on the inner surface of rearing containers elicited a… (More)
We describe a simple method for obtaining good a quantity of pure venom from a small parasitoid wasp, Melittobia digitata. Crushing the insect's head causes venom to be extruded from the ovipositor that dries rapidly as it is collected onto an insect pin. This technique may be applicable to other parasitic Hymenoptera.
Melittobia digitata (Hymenoptera: Eulophidae) are parasitoids known for their cooperative escape behavior. The initial sequences of this escape chewing behavior have been compared to the initial sequences of their feeding behavior. We sought to experimentally test whether these sequences were interchangeable. We were successful in turning off chewing and… (More)
