TWO SPECIES OF ENTOMOPHTHORA PATHOGENIC TO THE EASTERN HEMLOCK LOOPER (LEPIDOPTERA: GEOMETRIDAE) IN NEWFOUNDLAND
Abstract Two fungi, Entomophthora sphaerosperma and E . egressa , were collected and identified from larvae of the eastern hemlock looper, Lambdina f . fiscellaria (Guen.), in Newfoundland. These two fungi appear to play the most important role in the decline of looper infestations. Field trials ind...
