اثر چند نوع بستر پسماند روی طول دوره لاروی و شفیرگی مگس خانگی Musca domectica

In addition to conventional waste management methods, recent studies have focused on the use of insects for biodegradation of waste. One of the insect species widely used in waste recycling is house fly, Musca domestica (Dip.: Muscidae). Due to its high nutritional value, house fly larvae could be used in feeding poultry and fish. The current study was conducted to investigate the effect of five waste substrates on the length of the pre-adult stages of house fly at laboratory conditions under 25±2ºC, 50±10% R.H. and a photoperiod of 12:12 L: D. The experiment carried on in the form of a completely randomized design, which each treatment has 60 replications. The substrates used were the wastes of malting factories, slaughterhouses, the wastes of canned bean factories, kitchen wastes, and wheat bran as a control. The analysis of obtained results showed a significant difference in terms of the length of the larval period. Therefore, , the paired comparisons of treatments showed there was no significant difference in the length of the larval period of the house fly on the substrate containing beer waste with meat, beer waste with wheat bran, canned bean waste with wheat bran, and meat with wheat bran. However, in the treatments of beer waste with canned waste beans, beer waste with kitchen waste, canned beans waste with kitchen waste, canned bean waste with meat, kitchen waste with meat, and finally kitchen waste with wheat bran the larval period of housefly were significantly different at the probability level of 1%. Regarding the length of the pupation period, there was no significant difference between treatments. Considering the influence of the substrate on the life span of the housefly, these results could be used in the optimal breeding of houseflies.
