1.3. Refer tо the RESOURCES ADDENDUM fоr the grаph thаt gоes with this question. The cottony scаle insect first appeared in the Californian orange groves in 1868 following accidental introduction from Australia. In the absence of natural enemies, it quickly multiplied and within 20 years was causing major damage to the citrus trees. The fruit growers were close to ruin. Scientists studying the pest’s natural enemies found that a certain type of Australian beetle (a species of ladybird) could be used to clear the orange trees of the insect. Following the introduction of the beetle predators, the pest was brought under control within 2 years and the citrus fruit industry was saved. Scientists monitoring populations found that the cottony scale insect was continuing to survive in low numbers but was no longer posing a major threat to orange trees since it was being kept in check by the ladybirds. When later, the orange groves were treated with pesticide most of the scale insects died. However, a few were resistant to the chemical and survived. All the ladybirds, however, died. This resulted in a new epidemic of scale insects which was only curbed by the reintroduction of ladybirds. 1.3.1.
