“…The factors influencing the amount of radiation required to sterilize an insect have been discussed by Nelson (1968). Lepidoptera, whose chromosones have 5 diffused centromeres (Virkki, 1965) Ϊ show a high degree of radioresistance to the induction of sterility (North and -Holt, 1968b).…”

“…Females develop from fertilized eggs and are diploid (Schrader, 1923;Helle & Overmeer, 1973). Consequently, other control methods have been suggested such as the use of predators (Chant, 1961;Bravenboer, 1975) of incompatibility genes (Helle, 1969;Smith, 1975), of chromosomal translocations (van Zon & Overmeer, 1972, Overmeer & van Zon, 1973Overmeer, 1974) and of sterilized males (Nelson, 1968;Nelson & Stafford, i 972). Also because of great genetic variability (Helle & Pieterse, 1965), a rapid build up of multiple insecticide resistances has resulted following the successive use of several acaricides.…”

Males of Tetranychus urticae Koch were irradiated with X-ray doses of 4, 8, 24 and 32 krad (were applied to 0-1 day-old adult virgin males) and tested in mating competition with one-day-old nonirradiated males. A non-significant excess of parental females were mated to the unirradiated males. This consistent trend in favour of females, mated with unirradiated males was highly significant, when the results of all the experiments were bulked. This indicated that radiation impaired the mating competitiveness of males of T. urticae. Ageing of irradiated males resulted in a significant decrease of male-mating competitiveness at least within 2 days after irradiation. When 24 krad X-rays irradiated males were tested in mating competition at different ages, with unirradiated males of equal age, it was demonstrated that the reduction in mating competitiveness of ageing irradiated males is caused by accelerated ageing, due to the irradiation treatment.

Three different strains, homozygous for a radiation induced structural chromosome mutation (T), exhibiting negative heterosis, were tested for theirability to displace the standard (wild-type) karyotypefrom experimental populations. The experimental populations were initiated by mixing fertilized females of both a T strain and the standard strain at different ratios. Two of the T strains showed the ability to displace the standard karyotype if the initial frequency of the T karyotype was at least 0.65. The additional release of T males into the experimental population accelerated considerably the process of displacement of the standard karyotype, especially if the initial T karyotype frequency was 0.65.A computer model for simulating the process of population displacement in Tetranychus urticae was developed. The model accounts for variation in developmental time and for the age dependency of variables related to fitness. The simulations showed a good correlation with the experimental results. A system analysis on the sensitivity of the model output to varying different population parameters demonstrated that especially the relative number of males produced by a T strain and the female developmental rate were of significant importance to the population displacement ability of a T strain. The negative influence of genetic markers on general fitness and various aspects of practical application of the method are discussed. IntroductionSome common and serious pests were successfully combatted by the general introduction of synthetic insecticides shortly after the Second World War. However, although some old pests declined, other pests, previously unknown as such became significant (upset pests, De Bach, 1974). One of these upset pests is Tetranychus urticae (Huffakeretal., 1969(Huffakeretal., , 1970 McMurtryet al., 1979) which for two decades has been satisfactorily controlled by the development of a series of acaricides, just keeping ahead of the astonishing capacity of this species for development of resistance. The arsenal of acaricides is not depleted yet but past experience of unexpected resistances towards new chemicals, the awareness of the environmental impact of agricultural chemicals together with the risin...
