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

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

Chemistry &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

Plant-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.

Efficacy of Crude Extracts and Essential Oils of Selected Plants for the Management of Fall Armyworm (Spodoptera frugiperda) in Kenya

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), poses a serious threat to maize production in Kenya. This study aimed to assess the efficacy of crude extracts and essential oils of garlic (Allium sativum), red hot pepper (Capsicum frutescens), Sodom apple (Solanum incanum), and Mexican sunflower (Tithonia diversifolia) in controlling FAW ...
