Abstract:
[Objectives] The larvae of Protaetia (Liocola)
brevitarsis (Lewis) feed on crop stalks and livestock manure, which plays a
role in purifying the environment in nature. In order to better play the role
of biological conversion of agricultural organic waste. [Methods] The biological characteristics of P. brevitarsis were studied by using 8
principal agricultural organic wastes produced in agriculture and animal
husbandry, including the renewal, oyster
mushroom, pig manure, shard, corn stalk as well as shard mixed with 25% corn
stalk, 50% corn stalk and 75% corn
stalk as feeding matrix. [Results] The highest spawning
amount was obtained in the treatment of renewal and oyster mushroom, with
130.17 and 117.00 eggs/female; It was significantly higher than that of pig
manure, shard and corn stalk; Regarding the different proportion mixture
treatments of shard and corn stalk, the spawning amount was obtained in the
treatment with 101.50-108.67 eggs/female; there was no significant difference
between different mixing ratios. Compared with the larval hatching rate, the
larval hatching rate of oyster mushroom and pig manure was 87.78% and 82.22%;
The hatching rate of corn stalk mixed with shard in different rate was all very
low, only 46.67%-57.78%. From the rate of larval pupation and feather
comparison, The pupation rate and feather rate of corn stalk treated with
different proportion of shard were higher, reaching 90.00%-95.56% and 88.89%-91.11%.
The pupation rate and eclosion rate of renewal and pig manure were lower than
90% and 70%. In the treatment of single substance, the proportion of female
worms was higher than that of male worms in the treatment of renewal, oyster
mushroom, shard andcorn stalk. In the mixed treatment group of corn stalk and
shard, the proportion of female worms was higher than male worms in the 50%
corn stalk+shard groups.The length and width of female and
male adults were 17-19 mm and 10-11 mm respectively. The body length of
renewal, pig manure and shard treatment group was slightly smaller; Feeding
different agricultural organic wastes to the whole developmental cycle of P. brevitarsis, shard feeding group
turtle calendar period is the shortest, is (315.29±0.55) d; renewal feeding group turtle calendar period is the longest, is (330.75±1.76) d. [Conclusion] Different
agricultural organic wastes can be used as breeding grounds for P. brevitarsis, the production practice
in Xinjiang shows that it has the feasibility of high value utilization, it can
provide a theoretical basis for the larval transformation of agricultural
organic waste.
