“…Boller (1972) described a "production curve" for laboratory-reared insects, in which he predicted low reproductive performance in the first five generations with recovery in latter generations. A similar phenomenon has been described by Proshold & Bartell (1972) and Raulston (1975). Leppla et al (1980Leppla et al ( , 1983 described changes at colonisation as laboratory adaptations which were parabolic or nonlinear, characterised by rapid decline until the fourth generation, and total recovery by the sixth generation.…”

Close monitoring of the lepidopteran leafroller Cnephasia jactatana under laboratory colonisation revealed few distinct effects of successive rearing on artificial diet on the life cycle. The second laboratory generation had a prolonged development time and altered sex synchronism in pupation and eclosion patterns. Some deleterious changes were observed in later generations, including decreases in fertility, egg hatch and sperm motility, failure of mating adults to separate, and pupal and adult malformations. These changes were not adaptive, but were due to incompatibility with the general purpose diet (GPD) used; they were absent under sub-colonisation on a sheepnut-bean based diet (SBD). Success in the laboratory colonisation of C.jactatana is attributed to a random mating protocol, choice of environmental conditions representing the wild habitat, and a rapid rate of population growth.

“…In the tobacco budworm Heliothis virescens (F.) (Lepidoptera: Noctuidae) even larger differences in the response to radiation were demonstrated between a long established laboratory colony and one that had only been in the laboratory for three to seven generations (Proshold and Bartell 1972). However, in this case following reciprocal crosses between irradiated males and non-irradiated females it was evident that the origin of the female determined the difference in egg hatch and not the origin of the irradiated male.…”

The purpose of this study was to analyse the radiosensitivity of codling moth Cydia pomonella (L.) strains from different elevations, 850 and 2000 m above the sea level. The level of sterility of parental males and inherited sterility of F1 males in the strain from the higher elevation at all radiation doses (80, 100 and 150 Gy) was significantly lower, than in the strain from the lower elevation. The frequency of chromosomal aberrations in the F1 generation in the strain from the higher elevation was significantly lower at 80 and 150 Gy than that in strain from the lower elevation. The average number of eupyrene sperm in the F1 males descended from irradiated males was higher in the strain from the higher elevation than in the strain from the lower elevation. Inheritance of the resistance/susceptible to ionizing radiation were examined by standard genetic cross‐breeding analysis confirming the polygenic nature of the differences in radiosensitivity. The implications of these findings for the implementation of area‐wide integrated pest management programmes that integrate the use of sterile insects are discussed.

“…However, this may be true only for recently colonized stocks of species that are amenable to a laboratory environment. In some Lepidoptera, long-term (adapted) laboratory strains have a higher mating frequency than recently colonized strains (Proshold and Bartell 1972;LaChance et al 1975).…”

BIOSYSTEMATICS OF THE GENUSEUXOA(LEPIDOPTERA: NOCTUIDAE): X. INCIDENCE AND LEVEL OF MULTIPLE MATING IN NATURAL AND LABORATORY POPULATIONS

In most species of Euxoa a high proportion of the females mate more than once. The mean number of matings per mated female in natural populations of 13 species ranged from 1.65 to 10.86. Mating frequency data for laboratory populations of three of these species indicate that laboratory rearing and confinement does not significantly alter the incidence and level of multiple mating. The propensity for multiple mating is species characteristic although the observed level in samples from the field can vary significantly depending on the age structure of the populations sampled and probably also on other parameters of populations or environmental factors. Since species differences in the tendency for multiple mating are probably manifestations of different reproductive strategies some of the possible advantages of this behavior are discussed.
