Abstract: 
Splwerolecanium prunastri is a serious pest on almond (Prunus amygdalus) trees in Chahar-Mahal & Bakhtiari province. Coccinellids are the most important natural enemies of the pest in the province. During 1999-2000, specimens of coccinellids were collectcd using shaking method in weekly intervals. Collected specimens were identified based on male genitalia and external morphology characteristics. Identified species belongs to 3 subfamilies, 4 tribes and 7 genera. Exochomus quadripustulatus has the highest density among collected species. Adults of E. quadripustulatus were appeared gradually from early March and their population peaked at early April.
Larvae of the coccinellid increased in their activity and population from late April along with decrease in population of adults. Larval population were peacked from late April to early May and afterward decreased gradually. Adults were emerged from early May. Population of this gegneration were increased rapidly and peaked at late May-carly June. Overwintering adults were found from early September on the foliage and their activity peacked at early November.
