摘要
Some aspects of the biologies of Typhlodromus annectens De Leon and T. porresi McMurtry were studied at 25-degrees-C. The tetranychid mites Oligonychus punicae (Hirst), Panonychus citri (McGregor) and Tetranychus pacificus McGregor were all favorable foods for development of Ty. annectens, whereas a low survival rate of immatures and no oviposition occurred on pollen. Tetranychus pacificus appeared to be a less favorable prey than the other two tetranychids for Ty. porresi. Typhlodromus annectens, a very small species, and Ty. occidentalis, a medium-sized species used for comparison, consumed significantly more Te. pacificus larvae than did the medium-sized Ty. porresi. Comparing weights of fed and starved individuals suggested that Ty. occidentalis consumed the greatest volume of food material per time unit. The results are compared with those of previous studies of species in the occidentalis species group of Typhlodromus.
