The results indicated that the developmental duration and fecundity of the predatory mites were markedly affected by the food types.When feeding on Aleuroglyphus ovatus, Thrips flavidulus and Panonychus citri, the development duration from egg to the adults of Neoseiulus cucumeris took 7.1 d, 7.7 d and 7.4 d, respectively.The oviposition period of these females lasted 22.7 d、23.2 d and 25.1 d respectively, and the average number of eggs oviposited by the N.cucumerisfemales was 33.1、34.1 and 37.5, respectively.It lastsed the longest periods for N.cucumeris to complete the whole generation when fed with T.flavidulus, while the oviposition period of N.cucumeris lasted the longest time and the average number of eggs oviposited by N.cucumeriswas the most when fed withP.citri. However, the development from egg to the adults of Neoseiulus barkeri took 7.5 d, 6.4 d and 7.1 d, respectively, when fed with the above food.The oviposition period of N.barkeri females usually lasted 22.2 d、22.5 d and 23.4 d, and they produced 30.1、30.7 and 31.5 eggs on average.It lastsed the longest periods for N.barkerito complete the whole generation when fed with N.ovatus, while the oviposition period of N.cucumerislasted the longest time and the average number of eggs oviposited by N.cucumeris was the most when fed with P.citri. |
