Hermetia illucens (Linnaeus) as a Factor in the Natural Control of Musca domestica Linnaeus

摘要: Hermetia illucens, (Linn.) was reared in the laboratory from field-collected larvae. Newly hatched larvae required 2 weeks or longer to attain full growth at a temperature of 30. moist standard house fly breeding medium. No evidence paedogenesis demonstrated. Larvae displayed little resistance freezing. The pupal stage lasted 5 months temperatures ranging 21 28. Adult flies held around 30° C. were active and fed on hone,}'diluted with water sugar-water solutions. Adults eurygamous, refusing mate cages 25 cu. ft. volume. Sterile egg masses deposited. In combined cultures H. illucens Musca domestica Linn. per cent successful development flips decreased as number actively feeding increased. This relationship modified by total amount larval medium available. illcens not cannibalistic predacious larvae, although they ate dead flies. Field observations over period October 1957 through September 1958, upper San Joaquin Valley California, demonstrated adult activity April November, peak late August. occurred poultry manure throughout year, but relatively inactive during winter months. House very rarely found where abundant. Artificial infestation droppings prevented breeding, while adjacent control sections became heavily infested
