“…Protandry has been observed in several species of Lepidoptera including codling moth, Cydia pomonella L., (MacLennan, 1976;Riedl etal., 1976) and A. argyrospila in southwestern Quebec (Paradis & LeRoux, 1965). In my study, the only statistically significant differences in the developmental times of males and females occurred in A. rosana.…”

Two univoltine leafroller species, Archips argyrospila Walker and Archips rosana L., were reared from eclosion to adulthood on known or potential host plants. Both species were able to complete development on eight of the ten plants tested, the exceptions being apricot and peach. Rates of development differed among hosts, and indicated a range of host suitability. Differences in female pupal weights were apparent following the different rearing treatments, but these did not correlate with subsequent female fecundity. When development was compared between the two leafroller species, A. rosana had higher survivorship, more rapid development and higher female fecundity than did A. argyrospila, regardless of host. These findings indicate that A. rosana may successfully exploit a wider host range than does A. argyrospila. Comparisons of survivorship and developmental rates among hosts for each species of leafroller suggest that both species may have the potential for host-range expansion.

Podisus modestus (Dallas) has one generation per year in the boreal forest of Quebec. Adults hibernate in the litter and soil from mid-autumn to late spring. Overwintered adults were found in the field until the latter part of August. Adults mated shortly after emergence from hibernation. Females mated an average of three times during the summer; the maintenance of a supply of highly fertile eggs apparently required this periodic mating. Young adults, which emerge from August to October, neither mated nor laid eggs before hibernation.The preoviposition period after first mating was 10 to 19 days. Females laid an average of 7.9 egg masses (average of 16.7 eggs per mass) at intervals of 1 to 25 days on jack pine, and on Kalmia and Vaccinium spp.Eighty per cent of the eggs hatched successfully after a mean incubation period of 15.3 days; 12% did not develop while 8% developed and were destroyed, during hatching, by other first-instar nymphs in the brood. Maturing nymphs spent an average of 7.7, 7.7, 7.8, 11.9, and 23.8 days in each of the five respective stadia, and required 59 days from hatching to adult emergence. A logistic curve describes the relationship between developmental time and temperature. First-instar nymphs required no animal food, but during each of the last four instars animal food was required for maturation. The hunting and feeding behavior, food consumption, abundance and mortality of P. modestus are also described.

“…Thirty-eight species d parasites were reared from the three most common species (Mayer and Beirne, in press). The numbers are high as compared with other regions: 10 species were reared from A. argyrospilus in Quebec in 7 years (Paradis and LeRoux 1965) and 25 from A. argyrospilus and A. griseus (Rob.) in 3 years in Connecticut (Prokopy 1968).…”

Aspects of the Ecology of Apple Leaf Rollers (Lepidoptera: Tortricidae) in the Okanagan Valley, British Columbia

Populations of leaf rollers on apple can be influenced by the proximity of alternative host plants, notably rose, privet, and antelope bush, in part because larval dispersal is common. Indications are that leaf roller population increases caused by parasite decreases are ultimate consequences of pesticide treatments, so that reductions in spray programs will not necessarily cause potential leaf roller pests to become actual pests. The composition of the leaf roller fauna on apple m the Okanagan Valley becomes increasingly complex as the environmental water balance is changed by cultivation and irrigation. There are indications that heavy vehicular traffic can be harmful to leaf rollers and their parasites nearby.
