Anthraquinones From Epicoccum sp., a Fungus Isolated From Gut of Dione juno That Feeds on Passifloras

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
An Epicoccum fungus was isolated from gut of larvae of the butterfly Dione juno juno that feeds intensively on leaves of Passifloras. This fungus produces hydroxyanthraquinones that moderately inhibits growth of some Bacillus that coexist with the fungus in the insect gut, suggesting that it is probably important for microbial embalance in gut flora ...

EFFECTS OF CERTAIN INSECTICIDES ON EGGS OF SPODOPTERA LITTORALIS [PDF]

Egyptian Journal of Agricultural Research, 2014
Seven chemical insecticides were tested for their ovicidal activity against Spodoptera littoralis eggs, using two methods, namely dipping of tafla leaves containing 0-1 day old eggs and o-day old eggs were deposited on insecticide residues on tafla leaves. Rynaxypyr was the most promising. It was taken as the standard insecticide and given an arbitrary

Essential Oil Formulations From Salvia officinalis, Ormenis africana, and Mentha pulegium: Chemical Profiles and Insecticidal Activity Against Myzus persicae

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
The insecticidal potential of formulations based on Salvia officinalis, Ormenis africana, and Mentha pulegium essential oils was investigated against Myzus persicae. The combination of the three oils provided the most effective control, showing strong activity in laboratory assays and greenhouse trials.

Analysis of Dendritic Specializations in Two Classes of Kenyon Cells in the Mushroom Body of the Adult Honeybee, Apis mellifera

Journal of Comparative Neurology, Volume 534, Issue 5, May 2026.
Honeybee mushroom bodies (MBs), sites for learning and memory, house two classes of intrinsic neurons: class I and II Kenyon cells (KCs) that form synaptic complexes with boutons of projection neurons (PNs) from primary sensory neuropils. Dendrites of both KC classes were restricted to distinct unimodal MB compartments.
