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.
