Up to the present, no nutritional studies of the genus Musca have been made, despite the fact that M. dome8tica is extensively used for the laboratory testing of insecticides, and that in recent years, with the development of resistance to insecticides, the importance of physiological studies of the housefly has increased. In general, the nutritional requirements of insects for lipids are mostl...

A series of laboratory bioassays were conducted for the evaluation of the insecticidal efficacy of an isolate of Metarhizium anisopliae (Metschnikoff) Sorokin (Ascomycota: Hypocreales) against larvae of the Mediterranean flour moth, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae), under various temperature-relative humidity (r.h.) conditions. The fungus was applied at four doses (0, 8 × 106...

Use of insecticides can have disruptive effects on the environment. Replacing the chemical compounds in these insecticides with plant materials, however, can be a safe method with low environmental risk. In the current study, chemical composition and insecticidal activities of the essential oil from cardamom, Elettaria cardamomum L. (Maton) (Zingiberales: Zingiberaceae) on the adults of three s...

A flightless strain of Harmonia axyridis (Pallas) (Coleoptera Coccinellidae) was fed, at the larval and/or adult stage, on a liverbased artificial diet supplemented with lin-seed oil, which is rich in α-linolenic acid (C18:3n-3), an essential lipid for the fecundity of different insect species, and other unsaturated fatty acids. Biochemical analyses revealed that, compared to Ephestia kuehniell...

The effect of moisture source and diet on the development and reproduction of the pirate bugs, Orius thripoborus (Hesse) and Orius naivashae (Poppius) (Hemiptera: Anthocoridae) was examined in the laboratory. Both species had been collected in and around sugarcane fields in South Africa. Supplementing eggs of the flour moth Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae) with a green bean...

Environ Entomol 15: 369-372 (1986) ABSTRACT Sharing of the sex-pheromone communication channel by five species of P ~ Y citine moths was measured in a wind tunnel Overall, male pheromonal response was characterized both by high levels of interspecific attraction and broad overlap in the circadian periods of male response, with attraction to nonconspecific females 75% of that to conspecifics, on...

This study investigated the effect of several substrate types and moisture sources on the developmental and reproductive fitness of the zoophytophagous predator Orius laevigatus (Fieber) (Hemiptera: Anthocoridae) when fed a factitious prey (i.e. unnatural prey) Ephestia kuehniella (Zeller) eggs, or a meridic artificial diet based on hen's egg yolk. O. laevigatus is known to feed on plants as an...

Comparative efficacy of three different modified atmospheres: 100% CO2, 75% CO2 + 25% N2, and 22 ppm ozone were examined against larval mortality of the almond moth, Ephestia cautella (Walker) (Lepidoptera: Pyralidae) at temperature regimes of 25°C and 35 ± 2°C and 60 ± 5% relative humidity, and 9:15 dark and light. Wandering young larval instars, which are fast growing, large enough in size an...
