Abstract. The brown planthopper, Nilaparvata lugens(Stål) is the major rice pest in Thailand.Adults and nymphs suck the sap from the rice plant causing it to wilt and transmitting the grassy stunt and the ragged stunt diseases. The population suppression by the sterile insect technique is overwhelmingly a function of mating between sterile males and wild females. The objectives of these experiments were to determine the suitable dose which induces partially sterile in N. lugens and their effect on wild population in the field cages. One-day-old 4 th and 5 th instar nymphs and adults were irradiated in a 60 Co irradiator at the doses of 30, 60, 90 and 120 Gy. It was found that irradiation at the dose of 90 Gy induced complete sterility in female and 78.47 % sterility in males. The inherited sterility were transferred to their progenies and induced 51.46 and 77.00 % sterility in F-1 males and females. The irradiation as the mention dose did not affect mating ability. The competitiveness index was increased when the ratio of irradiated males per normal male was increased. The releasing irradiated males at 10 fold of normal males in field cages could suppress F-1 population 80.11 % and suppress F-2 population 80.32 % when compare with the control. This technique may be applied to delay and/or reduce seasonal increase of brown planthopper.

“…Low radiation doses do appear to have a negative effect on the competitive ability of E.saccharina females, with males remaining equally competitive [31]. The F 1 progeny of the partially sterile males (irradiated with sub-sterilizing doses) inherit semi-to complete sterility with the level of sterility of progeny higher than that of the irradiated parent [33,37]. The sterile F 1 progeny of irradiated males has also been observed to be male-biased, with males more sterile than females [33].…”

The sterile F 1 progeny of irradiated males has also been observed to be male-biased, with males more sterile than females [33]. As a result of the SIT research on E.saccharina, it is possible to raise large numbers of sterile E.saccharina in a laboratory exhibiting the necessary traits to be able to survive and mate.…”

A mathematical model is formulated for the population dynamics of an Eldana saccharina Walker infestation of sugarcane under the influence of partially sterile released insects. The model describes the population growth of and interaction between normal and sterile E.saccharina moths in a temporally variable, but spatially homogeneous environment. The model consists of a deterministic system of difference equations subject to strictly positive initial data. The primary objective of this model is to determine suitable parameters in terms of which the above population growth and interaction may be quantified and according to which E.saccharina infestation levels and the associated sugarcane damage may be measured. Although many models have been formulated in the past describing the sterile insect technique, few of these models describe the technique for Lepidopteran species with more than one life stage and where F1-sterility is relevant. In addition, none of these models consider the technique when fully sterile females and partially sterile males are being released. The model formulated is also the first to describe the technique applied specifically to E.saccharina, and to consider the economic viability of applying the technique to this species. Pertinent decision support is provided to farm managers in terms of the best timing for releases, release ratios and release frequencies.
