Краткое описание

Solenopsis mealybug was detected in cotton crops and ornamental plants in a number of locations in Queensland. Due to the widespread apparent distribution, eradication is not feasible. Symptoms on cotton include crinkled and twisted leaves, fewer flowers and bolls, smaller bolls and distorted/stunted plants. Although mealybugs are usually considered to be only a minor pest of cotton, occasional populations increase and hotspots of infestation occur. The industry and growers are exploring management options to limit the impact on cotton production.

Опасность
Mealybugs are small, sucking insects related to aphids. They form colonies on stems and leaves, developing into dense, waxy, white masses. Adult and juvenile ‘crawlers’ weaken the plants by sucking sap from leaves, twigs, stems, roots and fruiting bodies. Long range dispersal can occur via movement of plant material, agricultural equipment and machinery and on clothing. Wind currents may distribute newly hatched nymphs and crawlers may be transported by wind and rain. Severe infestations result in plant death, honeydew and sooty mould. Heavy infestations are not effectively controlled by pesticides.
