| Question: | "A number of yellow patches have recently appeared on my lawn. Looking below the turf I found quite large numbers of insect grubs similar to the leatherjacket, but with definite brown heads and six well developed legs. These appear to be responsible for the poor growth of grass on affected areas, so could you please identify them and suggest methods of control." |

| Answer/Response: | "The insects which you sent have been identified as the larva of the cock-chafer beetle which you probably know as a fairly large light-brown insect with dark-brown stripes which may be seen flying around quite commonly in the late summer in the South of England. The grubs are similar in their habits to leatherjackets, feeding on the roots and basal shoots of grass plants. It is not common for these grubs to occur in sufficient numbers to cause significant damage to turf areas, but recent warm weather is probably responsible for the large numbers which seem to be affecting your lawn at the present time. We would suggest chemical control with a suitable insecticide which should be effective. It would be best to use either gamma HCH insecticide, also known as Gammexene which is available as a 3 1/2% powder and which should be applied at 35g/m2 bulked with sand to ensure even distribution. An alternative would be a material based on Chlorpyrifos which is equally effective and is applied as a liquid at a rate of 80 litres in 200-600 litres of water per ha." |
