“…Smith)] were irradiated with sub-sterilizing doses of radiation (LaChance 1985, Arthur et al 1990, Arthur et al 1991. The overall low survivorship in the field trial indicates that large numbers of eggs would need to be used to have sufficient numbers oflarvae to serve as hosts for C. plutellae.…”

“…In particular, successful sterile males mating a wild female produce a large number of offspring biased towards males (depending on dose) and sterile at F 2 . It may be necessary to take crop damage from F 1 larvae into account (LaChance 1985), although during an eradication this should be of short duration. In addition, a synergistic benefit of the combination of two tactics has been demonstrated to occur, for example where sterile eggs oviposited by released sterile females have been shown to enhance the numerical response of egg parasitoids (Bloem et al 1998;Cossentine and Jensen 2000).…”

Global range expansion of pest Lepidoptera requires socially acceptable solutions

Caterpillars of key moth pests can cause significant losses in cropping systems worldwide, and globalization is spreading such pests. Failure to control some species can jeopardise the economics of food production. A Global Eradication and Response Database (http://b3.net.nz/gerda) was reviewed on known government-level incursion response programs specific to invasive Lepidoptera. Geographic range expansion of Lepidoptera was evident from 144 incursion response programs targeting 28 species in 10 families. The countries involved in responses to Lepidoptera were USA (104), Australia (8), Canada (7), New Zealand (6), Italy (3), Mexico (2), with the remainder with one programme each (Brazil, Czech Republic, France, Hungary, and Spain). Most programs have been undertaken since the 1990’s. Control options exist for the long-term management of Lepidoptera, but most have issues of cost, efficacy or non-target impacts that reduce their acceptance. Pheromone-based technologies are increasingly available and are generally highly compatible with other tactics. The development of tactics for new targets is a major undertaking, although previous programs can be invaluable. New and improved socially-acceptable technologies are needed to counteract range expansion in Lepidoptera, and usually need to be used in combinations to achieve eradication. The sterile insect technique, which involves mass-rearing and release of sterile insects to reduce wild populations of the pest, has been used successfully against a number of lepidopteran species. Several sterile moth programs are under development. New technologies must have a social license to operate in urban areas, where new incursions are frequently detected. This factor is likely to reduce tactical flexibility and increase the complexity of insect eradication.

“…Previous investigations have showed that the SIT would be more effective if only males were released (LaChance 1979). Proverbs and Newton (1962) and Rananavare et al (1989) reported that the release of completely sterile Cydia pomonella L. (Lepidoptera: Tortricidae) and P. operculella males was more effective than the release of males together with the females.…”

Genetic sexing technique based on the construction of a balanced lethal strain (BLS) has been proposed for Phthorimaea operculella (Zeller). The isolation of female with T(W;Z) translocation is a fundamental step to develop such a strain. Gamma irradiation was used to induce the requested translocations. The availability of sex-linked morphological marker is required to facilitate the detection of such mutations. Since a visible sex-linked marker has not been found in P. operculella, the main objective of our study was therefore to determine the possibility of using sex heterochromatin body as a marker to identify the required translocated females. The appearance of sex heterochromatin body and the analysis of sex chromosomes in F 1 females of irradiated P. operculella females were investigated. The percentage of abnormality in sex heterochromatin body in highly polyploid Malpighian tubule nuclei was positively correlated with the applied dose. Based on the appearance of this body, three mutant lines were isolated: elongated, small and fragmented lines. W chromosome was easily distinguished from Z chromosome when the analysis of pachytene sex chromosome bivalents of P. operculella females was carried out. The aberrations involved in W chromosome directly influenced the appearance of sex heterochromatin body in highly polyploid somatic cells of the isolated mutant lines. The results showed that sex heterochromatin could be used as sex determination and cytogenetic marker in P. operculella.
