Common Cockchafer Melolontha melolontha (Linnaeus 1758). It may be worthwhile re-sowing these particular paddocks, using a soil disturbing machine, in the year when damage is occurring rather than waiting until the following year. Egg hatching occurs in late spring about 6 to 8 weeks after being laid. This gave rise to events that seem bizarre from a modern perspective. Illustration of cycle, animal, cartoon - … Wet weather or cattle trampling can mask the indicators of which cockchafer is causing damage. The following suggestions are based on the anecdotal experience of farmers and contractors. The first two larvae stages, called instars, also last 6 to 8 weeks. Maikäfer flieg! Deeper and more fibrous rooting plants such as lucerne, cocksfoot and phalaris may be an option in some situations. Re-sowing damaged pastures by direct drilling with perennial ryegrass can be disastrous as the newly established root systems of the new pastures will also be attacked. Re-sowing by using equipment which churns the top 3 to 5cm of soil, such as a Roterra, appears to greatly reduce further cockchafer damage. Research is needed to assess whether liming is a viable control technique. Quite the same Wikipedia.

The redheaded pasture cockchafer has a two-year lifecycle. However, since pest control was increasingly regulated in the 1980s, its numbers have started to grow again. Grubs can spend 3 years underground (up to 5 years in colder climates) until they pupate. She may do this several times until she has laid between 60 and 80 eggs.

Because of environmental and public health concerns (pesticides may enter the food chain and thus also the human body) many chemical pesticides have been phased out in the European Union and worldwide. You can pour a mixture of water and biodegradable detergent on the affected areas in the garden. In the pre-industrialized era, the main mechanism to control their numbers was to collect and kill the adult beetles, thereby interrupting the cycle. The adult beetle is 25 to 30 mm long; dark head, black pronotum covered with short hairs, reddish brown ), which are native to North America, nor with the summer chafer (or "European June bug", Amphimallon solstitiale), which emerges in June and has a two-year life cycle. 1.2 Biology of the Common cockchafer, Melolontha melolontha 1.2.1 Morphology, life cycle and behaviour 1.2.1.1 Adult The Common cockchafer, Melolontha melolontha, is a beetle that belongs to the family of Scarabaeidae. There had been a great deal of damage caused by birds and a fox. If re-sowing is delayed till the cockchafer activity ceases, the prevailing cold conditions will lead to slow pasture establishment and delayed growth for several months. The adult beetles are squat, shiny and black to dark reddish-brown in colour. They grow to 10 to 15mm long and 8mm wide (Figure 1). Combined with the transformation of many pastures into agricultural land, this has resulted in a decrease of the cockchafer to near-extinction in some areas in Europe in the 1970s.

This requires pastures to have 2.5 to 3 leaves before grazing and a grazing residual height of about 5cm between clumps after grazing. When many larvae are present, pasture root systems are cut about 25mm below the soil surface. Lifecycle Life cycle of cockchafer. One application might kill the older, more active grubs that are close to the surface but chances are there will be younger grubs hiding deeper in the soil.
