Ecological studies on the olive scale insect: Leucaspis riccae Targ (Diaspididae: Homoptera) in Iraq



Ecological studies on the olive scale insect: Leucaspis riccae Targ (Diaspididae: Homoptera) in Iraq



Iraqi Journal of Agricultural Sciences "Zanco" 3(1): 77-84



Leucaspis riccae is reported infesting olive in Iraq for the first time, and the results of studies on the biology of the scale in an olive orchard are presented. Two generations were observed, the first from the end of April until mid-August, and the second from mid-August to the second half of April. Populations were highest in June and September. No crawlers were observed in winter. The western side and middle part of the trees harboured the majority of the population.
