I received a report this week from a strawberry grower that overnight he went from no eastern flower thrips to an average of 15 thrips per bloom. Eastern flower thrips are an occasional pest of strawberries. They are attracted to and feed on flowers, with the result being leathery fruit or fruit that fail to[Read More…]
Eastern flower thrips, an occasional pest of strawberries, have been reported in large numbers in central Indiana. They are attracted to and feed on flowers, with the result being leathery fruit or fruit that fail to ripen. This problem occurs every year at some level but has not been serious since 1994. Eastern flower thrips[Read More…]

The severe cold weather we experienced in early January had a dramatic effect on the number of surviving fruit buds on crops such as peaches. The impact was highly variable depending on a number of factors, primarily location within the state. If you have less than a full crop of any of your fruit crops,[Read More…]
Insects and other arthropods are cold-blooded (or more technically, poikilothermic), which means that they don’t generate their own body heat like we do, but must rely on the environment for their heat. Each insect has its own developmental threshold, a temperature below which no development takes place. For many insects, such as codling moth, that[Read More…]
Woolly apple aphids seems to be an increasing problem with a growing number of fruit growers. One of the difficulties with this pest is that it has both an aboveground form that feeds like most other aphids and a subterranean form that feeds on the roots. Both need to be controlled. After consulting with a[Read More…]
One of the first and most important parts of a good insect and mite management program is the application of an early season oil spray to control European red mites, San Jose scale, and several species of aphids. Scales overwinter on the tree as nymphs and European red mites and aphids overwinter as eggs. Because[Read More…]
One way insects communicate with individuals of the same species is with pheromones. Pheromones are volatile chemicals released by an insect that usually can be detected only by individuals of the same species. There are a number of different types of pheromones, but the most common type is the sex pheromone. Usually the females will[Read More…]
From my own observations and reports from growers, it appears that Japanese beetle populations are higher than they have been for a number of years. I’ve seen severe damage to small fruits, as well as the Pristine apple tree in my backyard. In addition, after insecticides are applied to knock them down, populations reappear after[Read More…]
For those of you who follow me or Peter on Twitter, you know that last week I found SWD larvae in raspberries at the Meigs Farm near Lafayette. Small fruit growers should be into their rigorous spray schedules now. If fruit are ripe or ripening, growers should be spraying approximately every 5 days. The available[Read More…]
