- In a majority of SIT applications the objective is not eradication. There are four strategic options, "suppression", "containment", "eradication", and "prevention",
in which the sterile insect technique (SIT) can be deployed as part of area-wide integrated pest management (AW-IPM) interventions (Hendrichs et al. 2005). Considerations of pest status,
biology and distribution affect decision-making in relation to strategy selection and determine feasibility assessment, and programme planning and implementation. Unrealistic expectations
of eradication were often associated with applying the SIT, resulting in high political costs to change a strategy during implementation. The choice of strategy needs to be assessed carefully,
and considerable baseline data obtained to prepare for the selected strategy, before embarking on an AW-IPM programme with an SIT component.
Until the early 1990s, the SIT was generally considered an appropriate technique for eradicating certain insect pests. This view largely resulted from the high visibility of the successful
screwworm eradication programme in North and Central America, and the assumption that the SIT was too expensive to compete with other control methods for routine pest management.
In recent years, however, suppression of an insect pest is increasingly being viewed as a suitable strategy due to: (1) crucial improvements made in the rearing techniques for some key insect
species, which have significantly improved the cost-effectiveness of the SIT, (2) increased restrictions imposed on the use of insecticides, (3) increased intermingling of commercial production areas
and human settlements which complicates the routine use of insecticides, (4) increased customer demand for "organic" products, and (5) difficulties in establishing effective quarantine
measures to maintain an area pest free (Hendrichs et al. 1995).
Suppression can be achieved more quickly than eradication, is less complex, demanding, and management intensive, and therefore less expensive in the initial years. However, a suppression
strategy requires continuing releases of sterile insects to maintain the low population level.
One major advantage of applying a suppression strategy is the significantly lower investment needed to monitor the pest population as compared with the intensive monitoring required in
an eradication campaign. Moreover, the set-up and rigorous implementation of effective quarantines (which demand legislation and considerable investment) to maintain a pest free area
are not needed or demand less attention and resources when a suppression strategy is applied. Another strength of the suppression strategy is the focus on environmental benefits compared
with conventional control methods (no longer disrupting the biological control of secondary pests). This strategy has gained acceptance mainly for pest insects of phytosanitary importance, since
a certain level of "crop damage" to agricultural commodities is usually acceptable. However, this concept is much less applicable to insect pests of veterinary, and particularly medical, importance.
