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

open access: yesAgrosystems, 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

Insecticidal Activity of Trichilia hirta L. (Sapindales: Meliaceae) Extracts Against Spodoptera frugiperda (Lepidoptera: Noctuidae) Larvae and the Identification of Bioactive Compounds

open access: yesChemistry &Biodiversity, Volume 23, Issue 3, March 2026.
Fruits of Trichilia hirta were extracted and fractionated according to solvent polarity. The resulting partitions were screened for insecticidal activity by evaluating larval mortality and weight after 7 and 14 days. LC‐MS analysis of the most active fraction enabled the annotation of secondary metabolites potentially associated with the observed ...

Role of Millets for Food Security Under Climate Change

open access: yesPlant-Environment Interactions, Volume 7, Issue 1, February 2026.
ABSTRACT The accelerating impacts of climate change pose significant threats to global food security, highlighting critical vulnerabilities within the agricultural system. As greenhouse gas emissions continue to rise, global temperatures have increased by 0.6°C over the 20th century, with projections indicating further increases of 0.1°C–2°C per decade.

Monitoring and Controlling the Infestation of Sitophilus Oryzae

open access: yesInternational Journal For Multidisciplinary Research
Nowadays, store owner are currently dealing with loss of total income as well as decrease in good stocks and grains. Heat control is favorable against grain insects and pests such as the S. Oryzae that can develop internally inside the grains. 40-50°C are considered lethal to these stored-grain insects.
