Pheromone trap apple tree mesh damager

The package contains 1-covered cardboard trap, 2-pheromone capsule, 2-glued adhesive base and 2-fixing parts. NORM 1 trap per apple tree APPLE TREE NETTING MOTH 1pc (Yponomeuta malinellus) the front wings of the butterfly are white, along the wing there are three rows of black dots, the back wings are silver gray, the wingspan is 18-20 mm. Butterflies hatch from pupae in the second half of July, their flight lasts about a month and takes place in twilight, windless weather. During the day, butterflies sit motionless on the underside of leaves and are not noticeable. After flying, the fertilized butterflies lay clusters of 20-80 eggs on thin branches, which are covered with 3-4 mm diameter shields, under which the small caterpillars that hatch from the eggs in the fall stay for the winter. From spring, the caterpillars feed on the leaves and make nests from the sap they secrete, in which they live as colonies, growing in 30-40 days into whitish or grayish-yellow caterpillars with a characteristic line of dots on the back, up to 18 mm long. They pupate in the same nests, the pupae develop for 2 weeks, and usually in the second half of July new butterflies hatch. An apple tree moth ready (butterfly), caterpillar and moth nest. Pheromone trap for the apple tree moth From time to time Estonian gardens are hit by years of increased occurrence of the apple tree moth. Even though the caterpillars of the yellowtail moth (Yponomeuta malinellus) do not damage the fruits, but the leaves, it also depletes the trees, and if the pest is abundant, the yield decreases (in addition to the unpleasant appearance of the trees). In the spring, the overwintered small caterpillars feed on the spongy tissue of young leaves (inside the leaves), but around the time of flowering, they emerge and start to make nests of secreted sap, into which they add more and more apple leaves for food. If the pest is present in large numbers, all the foliage is destroyed and the tree may become stunted. Butterflies of the apple tree moth hatch from pupae in the second half of July, their flight lasts about a month and takes place at dusk, usually in calm weather. By using 2-3 apple tree moth pheromone traps, you can detect the presence of this pest in your garden and estimate its abundance in your garden using traps. By using traps in larger numbers, they can help prevent the further increase of their numbers in the garden by catching the pest butterflies. The rubber capsules used in pheromone traps are impregnated with the odorant secreted by the female moth - a pheromone analogue that attracts male butterflies of the same species to the trap. Pheromones are not toxic and the doses used (l mg) are tiny and do not pollute nature. Assembling the trap The ends of the bottom face of the trap are broken up. The pair of glued bottoms is pulled apart and one glued base is placed on the bottom face with the glue facing up. A rubber pheromone capsule (dispenser) is placed in the center of the glue base. Fasteners are placed through the holes, with the help of which the trap is attached to the branch. The trap is hung as horizontally as possible on the southern or western outer branch of the apple tree, so that it is hidden from direct sunlight. When using pheromone traps for pest monitoring (monitoring), they are hung at a height of about 2 m so that they can be checked weekly. To do this, the trap is opened at the end and the insects are removed from the adhesive base using a spatula or the tip of a knife, and the number of apple moth butterflies in the trap is recorded. If the inspection shows that the adhesive base is dusty or covered with insects and debris, it must be replaced with a new one. When the pest is present in large numbers, when the traps catch 5-10 or more butterflies per trap on average in a week, it is advisable to carry out spraying and continue to monitor the number of apple tree moths after that, in order to decide whether a second spraying is necessary. If trapping catches are below the control criterion, it is advisable not to spray. With this, you save nature and save unnecessary expenses on insecticide. To prevent further increase in the number of pests, we recommend setting out a larger number of traps (i.e. mass harvesting). Catching out the butterflies of the apple tree moth with pheromone traps is very suitable for controlling this pest, especially in home gardens, where it is not recommended to use insecticides at all or as little as possible. For catching, you need to consider a trap for each adult apple tree or two young trees, and be sure to hang them higher, preferably at a height of 2-3 m, because the pest butterflies fly mainly in the upper third of the crown of the apple tree. After 3-4 weeks, the traps on the adhesive base, which are usually already dusty and covered with insects and debris, should definitely be replaced. If the flight lasts longer (depending mainly on the weather), both the adhesive base and the dispenser should be replaced in the second half of July. If the spare capsule is not needed, it can be stored in a sealed container in a cool place and used next spring. NB! The glue used on the bottoms is very sticky and cannot be washed off with water. You can use ordinary or white spirit to clean your hands; cooking oil etc. is less effective. If the body of the trap is not too damaged by the weather, it can be used again the following year, but only for the same insect species. In order to prevent a new increase in the number of pests in the garden, the use of traps should be continued in the future./ Nb!
