Cardboard strips with 3000 species.
Store in the dark.
Storage temperature: 5–10°C.
Storage after receipt: 18 hours.
Apply to control mainly tobacco whitefly in greenhouse. Apply Eretmocerus together with Encarsia Formosa only at low humidity (under 60%) and high temperature (over 30°С), when Encarsia becomes less effective.
Use infested pupae of whitefly every 2 weeks in ratio 1:3 units per m2. Introduce wasp early in the morning or late evening.
Tolerates high temperature and dry climate, humidity about 60%.
Wasp is 0,6-0,8 mm long, light-yellow or orange color with green eyes.
Development from egg to imago lasts 22 days. Females lay 3-5 eggs a day. During life females lay about 40-200 eggs. Prefers 2-3 larval instars. In 4 days larva appears from egg. Then it pierces hole in whitefly’s larva during 3 days and enters it to parasite. During 12 days it parasites inside the host and then adult of Eretmocerus comes from yellow pupa of whitefly. Life period of adult lasts 6-12 days. Population ratio is 1:1.
Males can eat larvae of whitefly, destroying 40% of pest population. Also eat honeydew of whitefly larvae. Larvae infested by Eretmocerus, become yellow. Do not use yellow traps for monitoring pest. If it is necessary to use traps to control thrips, then use blue ones.
