Most of these aphids are green peach aphid, exhibiting a wide range of colors depending on what they have been feeding. A few melon aphids are also being found.
Spider mites are still a problem, but in lesser amounts.
Thrips have started to increase in most greenhouses. They are on African violets, and other plants in flower. If these thrips go untreated they can cause distortion of new growth and reduce vigor. Along with the thrips comes INSV, but the incidence of INSV this year has been very low. Of course there was some on the NG IMP stock plants earlier, but rouging has successfully reduced virus incidence.
