CODLING MOTH AND CATERPILLAR KILLER
What are Caterpillars and Codling Moths and how do they live?
-
The caterpillar stage of the butterfly and moth's life cycle occurs in a wide range of shapes and colours and sizes. Very few of these are a problem to the gardener requiring any control
-
The most common and troublesome ones are the distinctive Large and Small Cabbage White Caterpillars (40mm and 25mm long respectively). The Large Cabbage White Caterpillar has distinctive yellow and black markings and a hairy body. The Small Cabbage White Caterpillar is pale green with a velvety appearance. Both have two generations a year with caterpillars occuring from spring to early autumn.
-
The Gooseberry Sawfly is a pest that attacks gooseberries and red and white currant and can strip them of all their leaves. All three species of the Gooseberry Sawfly Caterpillars are up to 20mm long, pale green (two species are heavily marked with black spots). Damage starts mid to late spring and there are several generations in a season.
-
The Codling moth (Cydia pomonella) is an agricultural pest which is native to Europe, but is found worldwide. Its larva is the common apple worm or maggot. It also attacks pears, walnuts and other tree fruits. As can be seen from the picture above it is greyish in colour with light grey and copper stripes on its wings. It has an average wingspan of 17mm. The female lays eggs on the fruit or leaves around June and the black-headed yellow larvae begin to attack the fruit immediately they are hatched by burrowing into the fruit and eating until early August. They then eat their way out of the fruit and overwinter and pupate in loose flakes of bark on the tree trunk and the moths emerge in the late spring.
-
Indoors, caterpillar damage can occur at any time.
What damage do they do and do I recognise it?
-
Cabbage White Caterpillars can decimate a vegetable plot. They love brassicas and ornamental beds, especially nasturtiums. The Large Cabbage White feeds mainly on the outer leaves, leaving holes or sometimes stripping the leaves. The Small Cabbage White feeds mainly on the hearts of cabbages and other brassicas.
-
By the time the fruit is ready for picking the Gooseberry Sawfly can have completely stripped the leaves of the bushes, leaving them severely weakened and ensuring a poor crop the next year.
-
The Codling Moth feeds on the core of the fruit of apples and pears and walnut and quince. Once they have eaten the fruit they exit leaving a small reddish brown hole in the skin with brown droppings known as frass. When the fruit is cut open there is usually very little that can be eaten.
Nemasys Caterpillar and Codling Moth Killer
-
This is the simple solution to control caterpillars
-
It should be applied as soon as the caterpillars are first seen, applied to all leaf surfaces where the pest is present. Ensure the pests are sprayed with a solution as caterpillars not directly sprayed will not be controlled.
-
To control Codling Moths apply September to October to the trunk of the tree/main branches and to an area of soil equal to the tree cover above.
-
Wet the area before applying the nematodes and apply with a pump sprayer so that all areas are treated. The pack contains sufficient for a further two applications at 5 to 7 day intervals which ensures that all the hatchings are targeted.
-
The nematodes (Steinernema carpocapsae) attack the pest by enetering natural body openings. Once inside they release bacteria that stops the larvae from feeding, quickly killing it and breaking the pest's life cycle.
-
Nemasys Caterpillar and Codling Moth Killer is supplied in a pack to treat 3 x 40sqm of open ground or up to 20 trees.
