Abstract: The exotic rugose spiraling whitefly (RSW),Aleurodicus rugioperculatusemerged as an important pest on plantation crops, especially coconut. Among the various natural enemies, the predatorApertochrysa asturwas found to be highly promising against RSW due to its amenability for mass production in the laboratory. As part of standardization of adult feed diet of this predator the diet comprising honey, Protein X, glucose, coconut pollen and yeast was found to be most suitable in the development of theA. asturadults and recorded superior biological parameters, especially in fecundity, larval hatching, larval pupation, male and female longevity and hatching too. Among the various protein substitutes evaluated instead of Protein X in the adult feed diet ofA. asturgreen gram, bengal gram and horse gram recorded parameters on fecundity, larval, pupal survival and adult emergence equivalent to Protein X included diet in F0and F1generations thereby providing scope in reduction of production cost of the predator.
