Example 2:

meanwhile, the invention also provides a feed for artificially breeding the larvae of the tobacco meal moth;

before preparing the feed, the corn grit and the half-crushed wheat are dried in an oven (60 ℃) for 1-3 hours to obtain the feed, the total weight of the prepared feed is determined, A, B, C three groups of experiments are made for comparison, the weight of each group of components is weighed according to the corresponding proportion (see table 1), the solid is weighed firstly, the liquid is weighed, and after all the materials are weighed, the materials are stirred uniformly;

TABLE 1 tobacco meal moth artificial feed formulation (g)

According to the feeding results in step S3, the artificial feed of the present invention was evaluated and analyzed as follows:

(1) the development period is as follows:

the tobacco meal moth eaten by the three feed formulas has insignificant development difference in the egg stage, the larva stage and the pupal stage, particularly has little difference in the egg stage. However, the survival rate difference from eggs to adults is remarkable (P <0.05), the survival rate of the feed A is as high as 75.91%, and the survival rate of the feed C is as low as 69.42% (table 2), but the survival rate of the tobacco pink borer bred by the three feeds is greater than that of the optimal formula C obtained by the high-home and the research of the people and the like.

TABLE 2 influence of the three feed formulations on the survival rate of the tobacco meal moth at the immature stage and from egg to adult

Note: values are mean ± sem. The different lower case letters in each column indicate significant differences (P <0.05, Duncan)

(2) Adult life, single-female egg laying amount and sex ratio:

as can be seen from Table 3, the three feed formulations have insignificant effects on the life span, the single female egg laying amount and the male-female ratio of the male-female adults of the tobacco meal moth. The average life of the female and male worms fed by the formula C is 10.00d and 9.00d respectively, which are higher than those of the other two feed formulas, and the egg laying amount of the female is the highest (67.40 grains). The sex ratio of the tobacco powder borers bred by the three feed formulas is close to 1: 1.

TABLE 3 influence of three feed formulations on the service life, ovipositivity and sex ratio of the tobacco meal moth imagoes

From the results, a large number of populations can be obtained by feeding the tobacco meal moth with the three feed formulas, but indexes such as a larval stage, a pupal stage, a survival rate and the like and economic cost are comprehensively considered, the feed B is considered to be the optimal formula of the tobacco meal moth, and the probability of the larval infection with viruses can be reduced by adding moroxydine hydrochloride tablets in the invention. Therefore, the formula has low economic cost, the bred insects grow consistently and can obtain a large number of adults, which has important significance for population multiplication. Therefore, the feed B has good development and application prospects for raising the tobacco meal moth.
