Methoprene, when incorporated into the food of laying hens at concentrations of 0.005 and 0.01%, produced 70.9 and 99.3% larval mortality, respectively, among house flies (Musca domestica L.) reared in the resultant poultry droppings. Exposure to the

When Spalangia endius was exposed to pupal house flies. Musca domestica , at host-parasite ratios of 0.5:1 through 25:1, the percentage of parasitism decreased and the number of parasitized pupae increased as the ratio of pupae to parasites increased

Augmentative releases of Muscidifurax raptor and Spalangia endius at an installation of caged laying hens in north Florida demonstrated that M. raptor does not seek Musca domestica host pupae beneath the surface of the soil and does not function well

In outdoor cage studies undertaken in the late summer of 1973, a method of estimating the absolute density of a stable fly (Stomoxys calcitrans (L.)) population was developed by correlating the average number of insects feeding or resting on a calf t

In July 1974 a 3-year feasibility study was initiated on St. Croix, U.S. Virgin Islands, on the use of the sterile-male technique as a replacement or adjunct to insecticidal or physical measures to control or eliminate the stable fly, Stomoxys calcit

A deterministic simulation model for mosquitoes based on a life history analysis was developed. Average daily survival values for the adult and immature stages based on data collected in the field were used as the primary factors affecting population

A model was developed that describes the interaction between a pest insect, the house fly, Musca domestica L., and a wasp, Spalangia endius Walker, a parasite of house fly pupae. The model is based on life history studies of both insects in the labor

Two repellents, deet and M-1960 (military clothing mixture), and a toxicant, resmethrin, were compared on military fatigue clothing in laboratory and field studies with mosquitoes and other biting flies to determine their effectiveness in protecting

An equilibrium population model is presented which involves very simple assumptions, namely that the mortality is density-dependent in the larval stages and constant for the adult. This formulation leads to a description of population levels in the p

Stable flies, Stomoxys calcitrans , collected at local dairies on St. Croix, U.S. Virgin Islands, were used to establish a colony for mass production of flies for a sterile male release (SMR) program. Daily adult production ranged from 250,000 to 300
