Comparative efficacy and studies of mode of action of minerals from diatoms against three species of filth flies

Medical and Veterinary Entomology, EarlyView.
Mortality for diatomaceous earth was observed as early as 2 h after exposure with 50% and 90% mortality at 3.5 and 4.6 h (LT50 and LT90, respectively) for Musca domestica. The LT50 and LT90 increased when the size of the fly species increased (M. domestica to Cochliomyia macellaria to Sarcophaga bullata) and increased for all three from 50 to 70 ...

Seagrasses are most vulnerable to marine heatwaves in tropical zones: local‐scale and broad climatic zone variation in thermal tolerances

New Phytologist, EarlyView.
Summary Under a changing climate, it is imperative that we understand how species may respond to temperature impacts, which can differ among populations of the same species due to local drivers. Thermal tolerance data, which can be used to assess an organism's upper thermal limits, is valuable to identify species and/or populations' susceptibility to ...

Cold hardiness mechanisms and modeling: existing approaches and future avenues

New Phytologist, EarlyView.
Summary Cold hardiness models are useful tools to predict cold damage in plants, such as those produced by unseasonal temperature cycles or by increased cold exposure. Although development of these models started about five decades ago, their applications remain limited.

Reduced snow cover at the alpine treeline: resistance and recovery of saplings

New Phytologist, EarlyView.
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Effect of temperature on growth and development of rice weevil [Sitophilus oryzae (L.) (Coleoptera: Curculionidae)] on polished rice

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Rice weevils (Sitophilus oryzae), a major storage pest, cause both qualitative and quantitative losses of stored grains. Normally, chemical insecticide along with fumigation is practiced for the management, but it creates health hazards. So, this study investigates the effects of temperature and duration of exposure on rice weevils. Completely
