TL;DR: It appears that C. buchanani is better host among the two hosts as because the life cycle was completed in shorter time, recording high fecundity and longer longevity.
Abstract: The present paper reports duration of different developmental stages as well as fecundity, longevity, oviposition periods, sex ratio, etc. of Tetranychus sayedi Baker & Pitchard on two medicinal plants, viz. Cryptolepis buchanani Roem & Schult and Justicia adhatoda L. under laboratory condition at 27.5 °C and 65% R.H. during February-March, 2016. The two hosts in which the life cycle was studied form two new records of hosts for this mite. It appears that C. buchanani is better host among the two hosts as because the life cycle (egg to adult) was completed in shorter time, recording high fecundity and longer longevity.

TL;DR: In this paper, a meta-analytic review of 42 studies on 26 spider mite species was conducted to determine the degree and direction of sex difference with environmental factors, including food quality and temperature.
Abstract: Sex dimorphism is ubiquitous in the animal kingdom and can be influenced by environmental factors. However, relatively little is known about how the degree and direction of sex difference vary with environmental factors, including food quality and temperature. With the spider mites from the family Tetranychidae as subjects, the sex difference of life-history traits in responses to host plant and temperature were determined in this meta-analytic review. Across the 42 studies on 26 spider mite species (N = 8057 and 3922 for female and male mites, respectively), female spider mites showed longer developmental duration than the males in all except two species. The direction of sex difference in development was consistent regardless of temperature and host plant. The 16 spider mite species in 33 studies generally showed female-biased longevity, with an overall effect size of 0.6043 [95%CI = 0.4054–0.8031]. Host plant significantly influenced the sex difference in longevity, where the males lived longer than females below 22.5 ℃, but the reverse was true at higher and fluctuating temperature. Host plant also influenced the magnitude of sex difference in longevity, with females living longer than males when reared on herbs but not on trees. This study indicated that life-history traits are highly variable between sexes under temperature and host plant influence, highlighting that environmental conditions can significantly shape the direction and magnitude of sexual dimorphism of life-history traits.
