Mate Choice: Investigation Of Mating Preference For Siblings Versus Nonsiblings In The Solitary Vespid Wasp Euodynerus Foraminatus, Omoury A. Chambegga Aug 1992

Mate Choice: Investigation Of Mating Preference For Siblings Versus Nonsiblings In The Solitary Vespid Wasp Euodynerus Foraminatus, Omoury A. Chambegga

Masters Theses

Caged wasps of Euodynerus foraminatus were given a choice of a sibling or a nonsibling for mates. Two types of experiments were conducted: female choice and male choice. For female choice experiments one female, a sibling male, and an unrelated male were introduced into an observation cage. For male choice experiments one male, a sibling female, and an unrelated female were introduced into an observation cage. Females preferred to mate with siblings, but males mated randomly with regard to family relationship.


Effects Of Hypoxia On Egg Development In The Giant Waterbug (Belostoma Flumineum), Miki Furuya Jan 1992

Effects Of Hypoxia On Egg Development In The Giant Waterbug (Belostoma Flumineum), Miki Furuya

Masters Theses

I quantified the oxygen requirements of developing eggs and the adaptive significance of male brooding behavior in the giant waterbug (Belostoma flumineum). Egg pads brooded by males, and egg pads experimentally removed from the dorsa of males and maintained in a metabolic shaker, were tested for hatching success in four oxygen treatments (5%, 8%, 10% and 21%-control) in a closed laboratory system. All of the control male brooded egg pads, and 100% of the eggs/pad, hatched whereas none of the egg pads hatched in the 5% oxygen treatment. Fifteen of 20 (75%) male brooded egg pads in the 10% oxygen …
