Farmers sprayed leechi trees to suppress populations of scale insects. this also killed the populations of a predatory lacewing that controlled the numbers of scales. soon the spraying did no good, and the damage to the leechi from the scales was greater than before spraying had occurred. few predatory lacewings exist in the trees now because

few predatory lacewings exist in the trees now because they were killed by the spray.

Explanation:

The spray that farmers used, as noted, also killed the populations of a predatory lacewing.

Due to this, few predatory lacewing remained that could not fully deal with the scale population.

This in turn led to the multiplication of scale now that their predators had been done away with.
