“…The feeding of GS slows down the growth of wild apricot trees, with the level of infestationt actually posing a great threat to the survival of wild apricot forests. At present, the research on GS mainly focuses on its biological characteristics; occurrence patterns; damage; prevention of infestation, and control techniques including parasitism and predatory natural enemies [22][23][24]. Understanding the effects of GS on its host plants is critical to develop mitigation strategies for conservation.…”

The globose scale (GS) (Sphaerolecanium prunastri Boyer de Fonscolombe) is a sucking insect that feeds on saps of wild apricot tree (Prunus armeniaca L.) in the Xinjiang Uygur Autonomous Region of northwestern China. It feeds on branches of wild apricot leading to poor growth, leaf yellowing and leaf drop, and sometimes mortality. Since the initial infestation in 2018, all the main valleys of wild apricot trees have been affected, but there is little research on the host’s physiological response to GS infestation. We measured the differences in growth between infested and non-infested wild apricots. The results showed that the diameter of shoot branches, the fresh weight, dry weight, length, width, area, and chlorophyll content of leaves, and the longitudinal diameter of fruit, were all significantly less for infested wild apricot trees than for un-infested wild apricot. The branch length of shoots, cross diameter, and weight of fruit also decreased, although the differences were not significant. Overall, GS infestation significantly reduced the growth of wild apricot trees.

Several harmful pest species can cause damage in apricot trees. Chemical control is the often preferred method in controlling these pests. Use of pesticides have generally resulted in pesticide resistance and eliminating natural enemies. Exochomus nigromaculatus is a predatory insect of globose scale and other scale insects. Inappropriate use of pesticides has been linked with adverse effects on non-target organisms (e.g., reduction of beneficial species populations and increase of pest populations). This study evaluated the side effects of five insecticides (Acetamiprid, deltamethrin, spirotetramat, sulfoxaflor, dimethoate) and a plant extract (orange oil) on immature stages of E. nigromaculatus using dry film method. Acetamiprid and deltamethrin caused the highest mortality rate (97.3%) besides standard toxic dimethoate. Sulfoxaflor accounted for approximately 70% mortality to E. nigromaculatus. In contrast, spirotetramat and orange oil caused less than 20% mortality to the predator. As a result of the dry film method applied against the pre-adult stage of E. nigromaculatus; dimethoate were classified as harmful (class 4), acetamiprid and deltamethrin were classified as moderately harmful (class 3), sulfoxaflor were classified as less harmful, (class 2) while spirotetramat and orange oil were classified as harmless. Thus, it is concluded that spirotetramat and orange oil are compatible with E. nigromaculatus.
