Abstract: | The effects of four pesticides on populations of the psyllid, Insnesia glabrascuta (Caldwell), were examined on ifit trees, Intsia bijuga (Colebr.) O. Kuntze. The pesticides tested were Cygon®, a commercial over-the-counter formulation of dimethoate; Avid®, a commercial formulation of avermectin; Actara®, a commercial formulation of thiamethoxam; and Conserve®, a commercial formulation of spinosad. All pesticides caused initial mortality to psyllids. However, psyllid populations rapidly rebounded to pre-treatment levels in the Cygon® spray and drench treatments, while densities remained below pre-treatment levels longest in the highest concentrations of Actara®, Conserve®, and Avid® spray treatments. Psyllid population suppression was probably linked to residual activity characteristic of the different compounds and to physiological changes in tree leaves induced by feeding psyllids. |
