Two New Polyketides From Streptomyces sp. SA61: Isolation, Structure Elucidation, and Insecticidal Activity Against Bemisia tabaci

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Isolation of six polyketides (including two new compounds, strekingmycins I and J) from earthworm gut‐derived Streptomyces sp. SA61 and their insecticidal activity against third‐instar nymphs of Bemisia tabaci. Strekingmycin A (1) exhibited the most potent activity (LC50 = 5.58 µg/mL), comparable to the commercial insecticide spirotetramat. ABSTRACT To

Diversity and Species Richness of Lepidopteran Stemborers and Their Host Plants Across Major Vegetation Mosaics of East Africa

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Lepidopteran stemborer populations in wild habitats are increasingly influenced by anthropogenic disturbances, including urbanization and agricultural intensification in addition to climate change, which alter community composition and diversity within fragmented native ecosystems.

Population Genomics Approaches Identify a Cryptic, Emerging Generalist Pest Complex

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Molecular gut content analysis and RAD‐seq analysis revealed a peanut pest complex where previously only one species was considered problematic. Both species exhibited a wide, but somewhat distinct, variety of plants among their diets, and peanut‐feeding was rare. Diet generalism combined with a stepwise pattern of dispersal among fields might underlie

Tolerance to Simulated Pod‐Borer Herbivory Among Several Genotypes of Extra Short‐Duration Pigeonpea (Cajanus cajan)

Legume Science, Volume 8, Issue 3, September 2026.
ABSTRACT Pigeonpea is a major global legume crop that provides nutrition and income for some of the world's poorest people. Global pigeonpea yields are constrained due to damage from flower‐ and pod‐feeding lepidopteran pests, particularly Helicoverpa armigera.

Effects of pupal hypoxia duration and holding temperature on quality control parameters of sterile Queensland fruit fly

Pest Management Science, Volume 82, Issue 9, Page 8382-8391, September 2026.
Queensland fruit fly pupae tolerate hypoxia up to 2 days without compromising quality. Prolonged hypoxia, especially at 25 °C, reduces emergence and flight ability. Storage at 18 °C is recommended. Abstract BACKGROUND The sterile insect technique is used to eradicate outbreaks of Queensland fruit fly (Q‐fly) Bactrocera tryoni (Froggatt) in fruit‐fly ...
