Description
Summary:The pergid sawflyHeteroperreyia hubrichifrom Brazil was screened under quarantine to determine its safety as a biological control agent of the exotic invader Brazilian peppertree,Schinus terebinthifolius(Anacardiaceae). No-choice host-specificity tests were conducted using 36 plant species in 15 families. Neonate larvae of the sawfly were exposed to the plants in a quarantine facility and in field trials in Florida and Brazil, respectively. The neonate larvae fed and completed their development to the adult stage only on Brazilian peppertree and cashewAnacardium occidentaleL. Although the sawfly larvae were able to feed and reach the pupal stage on cashew in Brazil, the adult female was not able to oviposit on this plant and oviposited only on Brazilian peppertree. The first instars fed slightly, consuming less than 5% (
