Comparative Toxicity of Aqueous Solutions of Boric Acid and Polybor 3 to House Flies (Diptera: Muscidae)

Abstract

LC 50 s and LT^s of boric acid and polybor formulated in water and 10% sucrose were determined for 3-to 5-d-old adult house flies, Musca domestica (L.), of mixed sex. Differences between boric acid and polybor toxicities were significant in 10% sucrose, but not in water. However, borates formulated in water had significantly lower LC50S than those formulated in 10% sucrose. Rate of kill for formulations in water was fairly uniform over time, whereas mortality from sucrose formulations was not observed until 17 h after treatment. Reasons for differences in the manifestation of mortality and possibilities for practical application are discussed.

Influence of diets on the rearing of predatory flies of housefly larvae

“…The adults were fed with a diet composed of milk powder, sugar and fish meal, in a ratio of 2:2:1, respectively. The diets were modified by Ribeiro et al (2000a) and Krüger et al (2004) from Hogsette and Koehler (1992) and Hogsette et al (2002) that used Gainesville and Budapest diets. The O. aenescens and O. albuquerquei larvae were fed according to Ribeiro et al (2000b) and Kruger et al (2003) modified from Hogsette and Washington (1995) and Farkas et al (1998), who used Gainesville and Budapest diets for larvae.…”

“…The nutritional basis of the diet for the Ophyra larvae is essentially protein, varying slightly from the proportions of protein and carbohydrates, making it difficult to obtain a standard production Hogsette and Koehler, 1992;Hogsette and Washington, 1995;Ribeiro et al, 2000b;Krüger et al, 2003). The use of similar diets reduces the cost of components and facilitates the creation of insects as biological control agents.…”

Development of <I>Hydrotaea aenescens</I> (Diptera: Muscidae) in Manure of Unweaned Dairy Calves and Lactating Cows

“…The laboratory strains of H. aenescens were colonized in 1989 from adults collected on a caged-layer poultry farm near Budapest, Hungary, and from adults collected on a caged-layer poultry farm near Dover, Hillsborough County, FL. Adults of both strains were kept in screened cages under standard laboratory conditions (26 Ϯ 2ЊC, 60 Ϯ 5% RH, a photoperiod of 12:12 [L:D] h.) and given ad libitum access to water, and one of the following dry adult diets: powdered milk, granulated sugar, and powdered egg yolk (6:6:1) (Gainesville) (Hogsette and Koehler 1992) or powdered milk and granulated sugar (1:1) (Budapest). Eggs were collected in the standard manner by allowing H. aenescens females to oviposit on cloth-covered balls of larval medium used previously for larval development (Hogsette and Washington 1995).…”

Evaluation of the Efficiency of Certain Attractive Toxic Baits for the Control of the House Fly, Musca domestica (Diptera: Muscidac)

“…Sub lethal effect is expressed as physiological impact on individuals that survive an exposure to an insecticide [38], for example, in changes of biological parameter, longevity, reproduction, fertility of eggs, pupation, adult emergence and development in the life history. Several biological effects are reported in the literature due to the use of sub lethal doses concentrations of insecticides [39][40][41][42]. Insecticide mixtures have been proposed as important tools for resistance management in different insect pests.…”
