Abstract

Fruit piercing moths (Eudocima spp.) are important pests of commercial fruit crops. Losses of more than 50 percent have been recorded in Queensland. Population estimates of adult Eudocima spp. were derived from surveys undertaken at two commercial orchards every five to six weeks. Counts of larvae on two species of host vines (Menispermaceae) at four sites in three habitats were undertaken at the same intervals. The availability and condition of these plants for larval utilisation was noted. Eudocima {Ullonia (Clerck) was the most important species attaining the highest adult population levels. This abundance correlated temporally with the presence of larvae on the main host species, Tinospora smilacina Benth. Seasonal variation in availability of suitable larval hosts in inland and coastal habitats was similar, though not correlated, to adult population levels. Larvae were not present in large numbers prior to the initial increase in adult populations observed in November 1996, even though suitable larval hosts were present. This suggests that migration may have been a factor. While larval host availability and condition appears to be closely associated with adult and larval numbers it does not fully explain the seasonal changes observed in adult populations.
