COMMENTS: Begin applications when insects first appear; do not wait until the plants are heavily infested. Khan, R. A. RESULTS Aphids can reproduce both asexually and sexually, however in Australia, the sexual phase is often lost. In cold climates, green peach aphids overwinter as eggs laid on woody perennial hosts, Prunus species, hence the common name.In the southeast, however, eggs are not produced, and only female aphids are present. Re-monitor paddocks after heavy rain before making spray decisions. It requires only 15-30 minutes of feeding for the aphid to infect a plant. Rainfall stimulates plant growth before the winter cropping season, providing hosts that encourage rapid aphid reproduction. ), with serious outbreaks occurring only sporadically. Plants can become sticky with honey-dew excreted by the aphids. During cool weather, individuals are usually more deeply pigmented. Judicious use of insecticides and taking advantage of biological controls are essential to extend the useful life of the available chemistries.

Non-crop hosts include capeweed, marshmallow, wild radish, wild turnip, Lincoln weed and other cruciferous weeds. The spread of the virus within a geographical area can be reduced by not planting peppers near other pepper fields. Aphid sampling should always include an evaluation of the presence and activity of natural enemies. COMMENTS: Highly toxic to bees; do not spray directly or allow to drift onto blooming crops or weeds where bees are foraging. An important factor in reducing virus spread is good field sanitation, especially the chopping or discing of crop debris immediately after harvest and destruction of alternate host plants. & Naveed, M. (2020). In virus-prone areas or after a period of high rainfall, regular aphid monitoring from autumn onwards is strongly recommended to detect aphids moving into crops, particularly along paddock edges.
