| Using Medicago sativa (L), Artemisia frigida Willd.Sp.Pl.and the mixture (1:1) to feed first instar of Calliptamus italicus, those of feeding Artemisia frigida Willd did not accomplish its life history, the developmental process about individuals of feeding the mixture(1:1)was more faster than those of feeding Medicago sativa. Using three kinds of food to feed adults of Calliptamus italicus for exploring the effect on growth and fecundity.The results showed that compared with Medicago sativa and the mixture,A.frigida Willd.Sp.Pl.restrained body length, weight, mating rate, living day of male and female, egg laying amounts of C. italicus, it also caused the advancing of mating period and the increasing of death rate, but the change of eggs in the oocyst was not significantly difference.Compared with Medicago sativa (L.), the mixture promote the increasing about the amounts of eggs in th e oocyst, the other indicators was not significant change.These results showed that planting both grasses isolated was very necessary in controlling the damage of C.italicus |
