Insect Control 101
The cooler, wet weather at the beginning of the summer has provided the perfect environment for flies and mosquitoes to live and breed. With the growth of these populations comes insect bites and carcass trimming that can cost producers up to $8/pig. There are so many options available for insect control that it can be overwhelming when designing a program.

Dr. Mike Catangui, a livestock entomologist and parasitologist from IVESCO, has put together a few fact sheets to guide producers and veterinarians in designing a program that will work for their situations. Below are a few options for fly and mosquito control based on some of Dr. Catangui's recommendations.

Seasonal Infertility Update
Seasonal infertility refers to the effect of the season on reproductive performance. It is the time of the year that the sows no longer want to be pregnant. This phenomenon is well known and has affected the markets for a long time. It is one of the reasons why less pigs farrow from November to January, resulting in less pigs for sale in the summer months.

There are several factors that account for seasonal infertility. Heat and shortening day length (photoperiod) are two of the main ones.

The heat factor generally occurs in weeks 27-32 of the year. The effects are dependent on the lo-cal conditions and how extreme they are. Evaporative cooling remarkably reduces this effect but has not totally eliminated it. It's critical to make sure that all fans are operating at their peak efficiency and that your evaporative cooling system is working .
