The two-spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae), is one of the most serious polyphagous pests worldwide. During intercropping periods, TSSM transfers to available green plants either economic or weeds. The objective of the current study was to determine the host suitability of alternative host plants. The selected promotive host plant for TSSM growth received the phytoseiid predator Typhlodromips capsicum Mostafa to feed on TSSM based on biological features and reproductive potential for prey and predator. Leaves of cheeseweed, bindweed and mint were promotive for TSSM females' longevity which lasted for 16.9, 16.3 and 16.3 days, respectively. The highest significant deposited eggs per TSSM female was recorded on cheeseweed leaves (43.6 eggs, and 3.57eggs/day) with a sex ratio of 2.6: 1 (72.25 % females). Based on TSSM longevity and fecundity, slender amaranth, groundsel, fleabane, wild oat and Jimson weed were less suitable host plants as sorted in descending order. The longevity, prey consumption and fecundity of T. capsicum females were studied on the most suitable plants for TSSM comprising rocket, parsley, mint, bindweed and cheeseweed as sorted in ascending order. The longevity of T. capsicum females on TSSM preferred plants were closely related and the highest significant prey consumption (total 75 and daily 3.95 prey individuals) reared on cheeseweed leaves accompanied by the greatest number of deposited eggs per female (total 38 eggs, and 2.54 eggs/day). The alternative host plants may play a role as a reservoir plant for phytophagous mites also provide food and habitat required for predators conservation during absence periods of major crops to keep biodiversity and natural balance.

The two-spotted spider mite, Tetranychus urticae Koch is one of the most important pests of deciduous fruit trees in Egypt. The reproduction, survival, and life table parameters of T. urticae on Kostata and Hachiya Persimmon cultivars leaves were studied under laboratory conditions of 15, 20, 25 and 30 ± 2ºC, 70 ± 5% RH and a photoperiod of 16L: 8D. The shortest period of incubation, immature stages and female longevity were 3.27, 8.92 and 12.98 days, while these periods for males were 3.35, 7.8 and 11.8 days at 30ºC on Kostata persimmon variety, respectively. 30 ºC gave the maximum value of intrinsic rate of increase (r m ) 0.243 and 0.297 individuals/♀/ day on and maximum net reproductive rate (Ro) 47.51 and 63.47 individuals/♀ on Kostata and Hachiya varieties, respectively. Maximum fecundity was obtained on Kostata variety at 30ºC at day 15 as 8.93 eggs/♀/day. It was concluded that the Hachiya variety was more favorable for T. urticae than Kostata variety resulting in the highest fecundity and reproduction at 30°C.
