Each spring, I know some of you may be using insect-pest monitoring traps for the first time, whether it’s in your orchard or backyard!

However, there are many beneficial, predatory insects you can be on the lookout for in your fruit plantings! These insects can be seen throughout the season, attacking aphids, mealybugs, caterpillars, mites, and even scale[Read More…]
I hope the growing season is going well for all fruit producers! For this issue, I am sharing a quick update on what we’re seeing in pheromone-baited monitoring traps placed in orchards at the Purdue Agricultural Center in Lafayette, Indiana (Tippecanoe County), as well as orchards of collaborating Indiana growers (thank you!) in Tippecanoe and[Read More…]
Some of our readers may have small, backyard orchards, or even just a couple of fruit trees (or vines, canes, and bushes!), that you enjoy for the aesthetics and also the fruit! If you’re like me, you’re thinking that having just a few fruit trees to manage won’t be so hard, and the effort will[Read More…]
The plum curculio (Conotrachelus nenuphar) is a small “snout” beetle (also known as a weevil – one of my favorite beetle groups!) that will feed on apples, peaches, pears, plums, and cherries.
