Host Relations

A list of the host plants and parasites of lepidopterous larvae reared during a study of the native hosts of parasites of the oriental fruit moth, Grapholitha molesta Busck, was published in 1935. Much additional data which have since accumulated appear worth placing on record, particularly the host relations of the parasites.

AbstractMacrocentrus ancylivorus Rohwer overwintered in larvàe of the strawberry leaf roller, Ancylis comptana fragariae (Walsh & Riley), at the rate of from 544 to 7,623 per acre of strawberry field. Not more than 300 per acre of peach orchard, could be expected to overwinter in larvae of the Oriental fruit moth, Grapholitha molesta (Busck). About half of the larvae of M. ancylivorus in leaf rollers did not survive the winter.

Influence Of Temperature On

AbstractLaboratory tests, at constant temperatures, were conducted to evaluate quantitatively the influence of temperature on development of the Oriental fruit moth, Grapholitha molesta (Busck). The results showed that at the highest temperature (30°C) some larvae had four instars and some had five, indicating a mixed population. Fifth instar larvae developed only at the highest temperature (30°C) where larval development was also most rapid. It can, therefore, be assumed that the Oriental fruit moth has four distinct larval instars when reared in the laboratory at 15°–24 °C.

AbstractExperiments and observations on Oriental fruit moths in cages and in a peach orchard showed that both males and females may mate more than once. The maximum recorded number of matings was 7 for males and 5 for females. Mating usually occurred in the late afternoon and early evening during the daily flight and egg-laying period. Males seldom mated oftener than once in 24 hours and they transferred only one spermatophore to the female per mating. In cages, males mated approximately 1.4 times each when confined with equal numbers of females. Of the females taken in bait traps in a peach orchard, an average of 2.9% had not mated, 78.8% had mated once, 14.6% twice, and 3.7% more than twice. The mating behaviour of the Oriental fruit moth was shown to be similar to that of the codling moth.

STUDIES OF FECUNDITY AND BEHAVIOUR OF THE ORIENTAL FRUIT MOTH, GRAPHOLITHA MOLESTA (LEPIDOPTERA: TORTRICIDAE), ON THE NIAGARA PENINSULA OF ONTARIO

Peach Orchard

AbstractUnsprayed apple trees measurably increased the numbers of the Oriental fruit moth, Grapholitha molesta (Busck), in adjacent peach trees in only 1 of 4 years, though the apples were rather heavily infested. The moth became evenly dispersed throughout a previously uninfected peach orchard within three generations. Caged orchard trees were unsatisfactory for studying behaviour because the environment within the cages differed from that in the orchard. Experimental studies indicated that fecundity of the females was variable between years and generations and a varying proportion laid no eggs. Intraspecific competition between newly hatched larvae occurred at low egg densities; egg mortality was small but mortality of newly hatched larvae was large.

During a study of the predators of the oriental fruit moth (Grapholitha molesta Busck), the thrips Haplothrips subtilissmus (Hal.) was found destroying the eggs of the moth and also those of European red mite (Paratetranychus pilosus C. & F.).

AbstractAn inexpensive, artificial diet made with carrot powder, a commercially available product of Saccharomyces fragilis, ascorbic acid, mold inhibitors, and agar gave as good or better yields of G. molesta (Busck) moths as was reared from apples. One moth per 1.25 ml of medium at a cost of.08c per moth was the best obtained.

Germination And Growth

Indian Paintbrush (genus Castilleja) is a group of attractive wildflowers in which some species are facultative parasites on native grasses during early growth. This study hopes to characterize optimum germination, cultural and host requirements of several species. Lots of 100 seed of wild-collected Castilleja coccinea (L.) Spreng. produced 22% germination without pre-treatment or presence of host plants 10 days after seeding at 21°C with 12 hours light. Seed soaked 24 hours in distilled water, 10 mg/l GA3 or-post-plant treated with Regal Crown nutrient and growth regulator soluotion did not significantly differ from above. Moist stratification at 4°C for 20 days significantly increased germination to 46%. Further stratification (up to 80 days) did not further increase germination. Additional data on light, temperature, media and presence of host plants will also be presented for this and other species.
