NEPH-TEC is a generalist predator of mealybug feeding on the eggs and small life stages thereof. The adult beetles as well as the larval stages prey on mealybug.
Nephus kamburovi is a small predatory beetle from the Coccinellidae family. Adult beetles are about 1.5mm in length, are mainly dark brow to black in color with two light brown dots on the rear end of the elytra. The larva is a yellowish cream color and has long curled white filaments over its body.
NEPH-TEC can be used in a variety of crops including citrus, vines and pome fruit.
Nephus kamburovi lays its eggs in the vicinity of its mealybug prey, on average an adult female can lay up to 150 eggs in her lifetime. After hatching the larvae immediately start feeding on mealybug eggs and small nymph stages. Both the adult and larval stages feed on mealybug. It takes Nephus kamburovi 25-28 days to complete the life cycle from egg to adult and adult beetles live for about 50 days.
The duration of all life stages is dependent on the ambient temperature. The upper and lower temperature tolerance of Nephus kamburovi is 20°C and 35°C respectively.
NEPH-TEC has a simple and fast in-field application method:
Step 1: Find the right spot – inside the tree or crop in as little sun as possible.
Step 2: Use the elastic band to attach the container to a sturdy perch.
Step 3: Remove the sticker from the emergence hole to allow the beetles to fly out. Alternatively, the beetles can be gently shaken from the packaging onto the plants in the vicinity of the prey.
Step 4: NEPH-TEC should be released early in the morning or late in the afternoon in mild temperatures.
