Parasitoidism Rate and Life Table Parameters of Aphytis diaspidis (Howard) (Hymenoptera: Aphelinidae) and Hemiberlesia lataniae (Signoret) (Hemiptera: Diaspididae)

Latania scale, Hemiberlesia lataniae (Signoret), has become a major pest of avocado (Persea americana Mill.) in Chile and has reached high populations in the fruit because of limited natural control. The objective of this study was to identify the biological parameters of the parasitoid Aphytis dias...
