“…A interferência de diflubenzuron na produção de descendentes por adultos de D. gazella e de outros insetos não alvos já foi relatada por outros autores (Pickens e Miller, 1975;Fincher, 1991 Blume et al (1974) relataram que methoprene nas concentrações de 100, 10, 5 e 1ppm, diretamente misturado às fezes bovinas, inibiu a eclosão de ovos de D. gazella. Entretanto, Fincher (1991) não notou interferência desse IGR na produção de descendentes deste coleóptero.…”

“…No entanto, deve-se considerar que, em razão do baixo número de descendentes obtidos em todos os grupos no experimento em que se obteve a segunda geração de besouros em laboratório, os resultados obtidos não devem ser considerados conclusivos. Deve-se ressaltar que Blume et al (1974) Methoprene a 0,2ppm não afetou a duração do ciclo de vida da primeira geração de descendentes (H= 0,446; 1; P= 0,504), mas alterou a duração do ciclo de vida da segunda geração de besouros a ele exposta (Fig. 2) …”

RESUMOVerificou-se a ação dos reguladores de crescimento de insetos (IGR), diflubenzuron e methoprene, sobre o besouro rola-bosta africano, Digitonthophagus gazella (Fabricius), um inimigo natural da mosca-doschifres, Haematobia irritans irritans (Linnaeus). Casais de besouros foram colocados em baldes contendo terra úmida e alimentados com fezes bovinas contendo 1, 0,5 ou 0,2ppm de diflubenzuron e 0,2ppm de methoprene. Os insetos e sua prole foram recuperados com o auxílio de armadilhas pitfall. Diflubenzuron e methoprene não afetaram a sobrevivência dos adultos inicialmente expostos, mas interferiram na produção de descendentes. Diflubenzuron, nas concentrações de 1 e 0,5ppm, também afetou a duração do ciclo de vida dos besouros. Nenhum dos IGRs alterou a razão sexual dos descendentes obtidos. As concentrações testadas de diflubenzuron mostraram-se moderadamente nocivas ao besouro enquanto methoprene a 0,2ppm mostrou ser pouco nocivo, segundo os critérios da International Organization for Biological Control.

“…development was inhibited by 100, 56, 33.3, and 8.7%, respectively (Blume et al 1974). All these concentrations were above the concentration (0.08 ppm) sufÞcient to kill the target insect, horn ßy.…”

“…However, at concentrations of Ͻ0.08 ppm, methoprene has been successfully used for control of the immature stages of horn ßy developing in manure (Blume et al 1974, Fincher 1991. Methoprene can be administered orally either as a bolus (1.5 and 3.0%), mineral supplement (10.5%), feed additive (0.4, 1.0, 2.0, and 10.5%), or directly in the drinking water of cattle (Blume et al 1974, Harris et al 1974, Beadles et al 1975, Fincher 1991. The percentage of active ingredient present in formulated products varies greatly (U.S. EPA 2001).…”

“…When methoprene was mixed directly into manure at a concentration of 100, 10, 5, or 1 ppm, it inhibited egg hatch in O. gazella by 100, 56, 33.3, and 8.7%, respectively (Blume et al 1974). Manure from a steer treated with methoprene at a rate of 1 mg/kg body weight also inhibited egg hatch up to 32.6%, but there was no apparent effect on surviving larvae or on adults (Blume et al 1974).…”

Effects of the Insect Growth Regulator, Methoprene, onOnthophagus taurus(Coleoptera: Scarabaeidae)

et al. 2009

A bioassay was conducted to determine the impact of methoprene, an insect growth regulator (IGR), on fecundity, larval survival, and size of progeny for Onthophagus taurus Schreber. Adult O. taurus dung beetles were offered methoprene-treated manure in three to five replications each at concentrations of 0.08, 0.45, and 4.5 ppm, respectively. An additional group of adult beetles was immersed in a methoprene-water solution and allowed to reproduce in containers with untreated manure. Data from all treatment groups were compared with untreated control groups. Methoprene did not seem to hinder brood production at 0.45 ppm. Survival of O. taurus was not affected by methoprene-treated manure at 0.08 ppm or when parent beetles were immersed in methoprene-water solution. However, progeny survival was significantly reduced on manure treated with methoprene at 4.5 ppm. Mean pronotal width of O. taurus progeny was significantly smaller in beetles fed methoprene-treated manure (4.5 ppm). The low dose of 0.08 ppm did not affect pronotal widths nor did topical application of methoprene to adults affect pronotal widths in resulting offspring. Although some adverse effects of methoprene were observed at higher concentrations, use of methoprene at concentrations of 0.08 ppm as part of a horn fly control program likely would not greatly affect populations of O. taurus, the most common paracoprid dung beetle in North Carolina.
