For those growing apples with organic or “softer” pesticide programs, you might spot signs and symptoms of a hungry caterpillar that prefers to attack apple leaves and fruit: the redbanded leafroller (Figure 1). This particular apple pest is more often a problem in orchards where conventional insecticide sprays are not used. This season, I have[Read More…]
Insect Management
Dear readers, I hope your spring and summer seasons are off to a great start! I haven’t heard much in the last couple of weeks about common fruit insect pests, so I thought I would highlight an interesting, but probably uncommon insect issue for most readers of Facts for Fancy Fruit: the round-headed apple tree[Read More…]
Last week I had the wonderful opportunity to visit a local grower who installed an insectary strip adjacent to their high tunnel last year. They will be hosting a field day in June, so I wanted to take a sneak peek and see how the plants (and insects) were doing. The plants are progressing well,[Read More…]
Lygus is a genus of insects within the family Miridae (Order: Hemiptera, piercing-sucking true bugs) that often feed on common horticultural crops. These small insects have rather large eyes, heavily patterned, neutrally colored wings, and long spindly antennae. The diet of Lygus bugs, as they are colloquially called, is incredibly diverse ranging from cotton and[Read More…]
Dear readers, I have never been so excited to sort through trap catch from spotted-wing drosophila (SWD) monitoring traps (Figure 1A) as I have these last few weeks!! And it’s not just because I’m a bug nerd over here, ha! This season, as I’ve been looking through the contents of SWD jar traps, I’ve seen[Read More…]
I’m hearing that thrips are throwing many of us for a loop this season! Some of you may know that thrips do not overwinter here in Indiana, so each spring season they migrate up our way on winds blowing up from the south. Sometimes these southern winds occur earlier or later each spring, depending on[Read More…]
Hi fruit growers! Hopefully the season is going well for all of you. I am hearing from several folks that fruit development is ahead of where it was this time last year, and maybe that’s why I’m also getting a lot of questions about ‘unusual’ damage to the leaves and fruits of caneberries, apples, and[Read More…]
Many readers will remember when a massive brood of periodical cicadas (Brood X) emerged throughout Indiana back in 2021. With their dark bodies, red eyes, and orange wings, these insects look like something straight out of the X-files, am I right?? There was lots of noise (male cicadas singing for the females!), lots of cast[Read More…]

San Jose scale attacks all the delicious fruit trees: apple, peach, pear, and plum. Some of you may already know that this insect is particularly difficult to manage, because most life stages are very small, even tiny, so they are not obvious until there are lots of them! In fact, you’re going to need a[Read More…]
