Effect of Temperature on the Development of Tetranychus telarius L.

Ecology of tetranychid mites and their natural enemies: A review: III. Biology, ecology, and pest status, and host-plant relations of tetranychids

“…Examples are Oligonychus punicae (Hirst) (McMurtry and Johnson, 1966), Tetranychus desertorum (Nickel, 1960), Panonychus citri (Jeppson et al, 1957) and T. urticae (Gasser, 1951;Linke, 1953;Hussey, Parr, and Crocker, 1957;Bravenboer, 1959). Jepp son et al (1957) found that high popula tions of P. citri may occur even in winter in southern California, and Hussey, Parr, and Crocker (1957) found that, in green houses, the duration of the egg stage for females of T. urticae decreased from 5.9 days at 21.1° C to 2.3 days at 35° C, and the duration for larvae, protonymph, and deutonymphs combined, decreased from 7.4 days at 21.1° C to 3.4 days at 32.2° C, and rose to 4.1 days at 36.7° C. The re tardation perhaps partly resulted from the necessity for frequent transfer to fresh leaf disks because leaves deterio rated rapidly at 36.7° C.…”

Resistance to the two-spotted spider mite, Tetranychus urticae (Koch), in New Guinea Impatiens

“…Harrison and Smith (1961) found that mean incubation periods for the eggs ranged from 2.4 days at 32.5°C to 33.2 days at 11.5°C. Hussey et al (1957) Humidity also is important in spider mite ecology. Winston (1963) stated that both gain from and loss to the at mosphere of water by mites is fundamental to their existence.…”
