| | Bartlett & Staten: SIRM & Other Genetic Control Strategies |
 | | Some disadvantages of this technique are the possible breakdown of the translocation stocks due to crossing-over, contamination of the strain by wild-type individuals, and partial sterility of the strain due to the translocation. | | | There are difficulties encountered when SIT is applied to certain Lepidoptera, Coleoptera, or to insects (like mosquitoes and houseflies) whose obnoxious behavior precludes the release of large numbers in the vicinity of people or animals. | | | It is obvious that each of the previously mentioned phenomena requires significant research data on insect genetics, physiology, behavior, and reproduction to bring any of the techniques to fruition. |
