ABSTRACT：The composition of artificial diet for larvae of Bactrocera tau (Walker) was optimized by orthogonal design with 3 factors and 3 levels. C source (glucose, sucrose and maltose), N source (yeast extract and peptone and beef extract and peptone, yeast extract and beef extract) and vitamins (Vc, VB1, and vitamin B complex) three factors three levels to optimize selection, with Bactrocera tau (Walker) hatchability and single female worm spawning peak average spawning quantity as the main index and emergence rate, pupation rate, male and female adult life these four as reference indicators, select Bactrocera tau (Walker) different optimal composition adult artificial feed formula to deal with 4 (sucrose, peptone, yeast extract and VB1). Formula 4 get single females average spawning were the highest in the three generations, list female average amount of peak laying eggs was (498.33±15.45)grain, (475.00±12.29)grain and (416.67±16.51)grain. Three generations in the formula 4 of the hatching rate second only to the highest formula 9, followed by (50.67±1.20)%, (43.00±1.16)% and (44.00±1.73)%, formula of 9 hatching rate was (60.67±1.20)%, (62.33±1.20)% and (61.00±1.53)%. Formula 1 in the first generation of adult emergence rate (78.00±1.16)%, Second generation in the formula 1 of adult emergence rate (78.00±1.73) %, the third generation of formula 4 of adult emergence rate (76.33±0.88)%. Formula 1 and formula 4 of pupation rate had no significant differences in the three generations, formula 1 of pupation rate highest in three generations, three generations in the order of (90.00±1.16)%, (91.67±1.76)% and (91.67±2.33)%. Formula 1 female life in the first and second generation of the highest was (106.00±1.45)d and (100.67±2.19)d, the third generation of the formula 4 female insect life is the highest was (102.00±1.53)d. Formula 1 male life expectancy of the highest in the first and second generation of (113.67±0.88)d and (113.67±0.88)d, the third generation of the formula 4 of the male life times for (110.33±0.88)d. And by using the orthogonal experiment design method for Bactrocera tau (Walker) artificial feed four main components of sucrose, yeast extract, peptone, ascorbic acid and the preservative under the different amount of combination optimization selection, with Bactrocera tau (Walker) larvae survival rate and average spawning peak of single female insect laying eggs as the main monitoring indicators of pupation rate and emergence rate, pupa weight these three reference indicators, select Bactrocera tau (Walker) the same formulation under different quantity of adult best artificial feed formula to deal with 6 (sucrose=80.0g; yeast powder=40.0g; peptone=10.0g; ascorbic acid and sorbic acid=5.0g). This formula of pupation rate (90.00±2.31)%, emergence rate (76.00±1.73)%, larval survival rate (94.33±1.76)% and egg production per female during peak laying eggs was (496.00±12.74)grain, pupa weight was (12.67±0.04)mg.
