DOI: 10.1007/s10526-019-09937-1
Abstract: Predaceous ladybird beetles are known to consume alternative foods from flowers, especially when prey is scarce. Flower-rich semi-natural habitats in agroecosystems generally host a diversity of natural enemies, including predaceous ladybird beetles, suggesting that the… read more here.

DOI: 10.1007/s10526-020-10019-w
Abstract: The population density of Eucallipterus tiliae (L.) (Hemiptera: Aphididae) required for initiating oviposition in Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) was established in Tilia cordata Mill. (Dicotyledoneae: Tiliaceae) stands sampled weekly throughout the vegetative seasons of… read more here.
