was 18.5 larvae per 8-inch band. This means that 46.3 percent of the 
overwintering larvae are still present in the soil as live larvae and 
pupae and will, upon emergence, have ample opportunity to oviposit on 
first-crop figs and apricots. These data indicate that larvae hiber-— 
nating under grapevine bark emerge before a general food supply is a- 
vailable. They serve, however, as the reservoir for overwintering 
parasites. Larvae in the soil, on the other hand, emerge later in the 
Spring and are relatively free from parasites. Larvae hibernating in 
the soil must be considered as an especially effective source of moths 
from the overwintering brood of larvae." 
Mulberries furnish food for larvae of the raisin moth.-—-Mr. Don- 
Oohoe states that "A sample of mulberries collected from the ground on 
June 6 and examined June 24 yielded 48 larvae, or an average of 1,024,000 
per ton of dry fruit. Mulberries begin to ripen and fall to the ground 
early in May and continue to produce fruit throughout June. Although 
not a commercial crop, a brief survey has shown that they are extensively 
planted about farmsteads for shade. The fruit is allowed to drop on the 
ground unharvested. During the period of mulberry production, prior to 
the middle of June, no other known food for larvae exists. The fact that 
moths which emerge before ripening of other fruits are able to lay their 
@ges on mulberries is of importance. The result is that an extra brood 
of adults is produced in the spring which will emerge to infest fruits 
in July, when the population of adults would otherwise be at a minimun."
