Fewer pests due to cold weather in May and June, but also less fruit and birds

A leading entomologist and insect pheromone expert said the late Spring cold spell could have many knock on effects for wildlife and agriculture.

Dr Sam Jones, technical director for International Pheromone Systems, said the extended cold weather in late Spring delayed development of many insects which certainly means there will have been fewer insects around for birds to feed their young.

Dr Jones said: “Many bird species will have delayed producing eggs and perhaps have laid smaller clutches in response to this. Many insects that overwinter as adults are likely to have suffered in the extended cold spell also.

“The Codling moth is the most damaging insect when it comes to apple crops. The larvae that overwintered would normally have developed into adult moths by mid-May but this has been delayed a few weeks. If we don’t have a particularly hot summer, it is likely that there won’t be a second generation of adults in August so there will be less damage from this pest during the year.”
