Pest categorisation of Oligonychus mangiferus

open access: yesEFSA Journal, Volume 19, Issue 11, November 2021., 2021
Abstract The EFSA Panel on Plant Health performed a pest categorisation of the mango red spider mite, Oligonychus mangiferus (Rahman and Sapra, 1940) (Acari: Prostigmata: Tetranychidae), for the territory of the EU. This species is not included in the EU Commission Implementing Regulation 2019/2072.

Effect of temperature on the sex ratio and life table parameters of the leek‐(L1) and tobacco‐associated (T) Thrips tabaci lineages (Thysanoptera: Thripidae)

open access: yesPopulation Ecology, Volume 63, Issue 3, Page 230-237, July 2021., 2021
The proportion of females increased as temperature increased and decreased as temperature decreased. Preoviposition period, oviposition period, fecundity and adult longevity, and egg hatchability rate were reduced significantly with increasing temperature. Abstract Temperature strongly affects insect biological response.
