Structural and Functional Co-Adaptation of Plants of the Genus <i>Lysimachia</i> L. (Primulaceae) and Pollinating Insects of the Genus <i>Macropis</i> Panzer (Hymenoptera, Melittidae). [PDF]

Ecol Evol
The co‐adaptation of bees from the genus Macropis and Lysimachia plants has been studied in detail. Research shows that bees collect not just pure liquid oil from flower petals but tear off trichome heads filled with oil, transferring them to their nests.

Resistance mechanisms in collard green genotypes to Plutella xylostella: role of physical and morphological traits

Pest Management Science, EarlyView.
Resistance to Plutella xylostella in collard greens is mediated by antixenosis and antibiosis, associated with traits such as leaf wax, hardness, and color. Genotypes showed strong resistance potential, supporting their use in breeding and integrated pest management strategies. Abstract BACKGROUND The diamondback moth, Plutella xylostella (Lepidoptera:
