【 摘 要 】

http://dx.doi.org/10.5007/2175-7925.2013v26n2p105  Tetranychus urticae(Koch) stands out as a polyphagous mite. In a strawberry plant, this mite develops on the underside of leaves, causing a significant injury. This study aimed to know the biological characteristics ofNeoseiulus californicus(McGregor), from cultivated strawberry plants. The study started with thirty eggs isolated in arenas with different stages ofT. urticae . The average length of egg-adult was higher for females (5.69±0.08) than for males (5.35±0.11). The sex ratio was 0.66 and the innate capacity for increase (rm) was 0.15 female/female/day. The net reproductive rate (Ro) was 17.10 times/generation, with an average to each generation (T) of 19.35 days. Greater oviposition was observed at the 11th day after its onset, with 2.7 eggs/female/day and the average was 38.14±5.58 eggs/female. The finite increase rate (λ) was 1.41 female/day.  Neoseiuluscalifornicusshowed to reproduce properly when feeding onT. urticae .
