Researchers at Purdue University and The College of Wooster are conducting a study to learn more about insect pest management practices used by vegetable producers in the Great Lakes and Mid-Atlantic regions of the US. Although there is a key insect we’re curious about (the carrot weevil), you’ll only see 1 question about it; the[Read More…]
Insect and Mite Management
Over the last few years, we’ve heard of 2 or 3 unusual cases of high tunnel tomato producers losing entire crops of their tomatoes, with plants suddenly looking brown and covered in leaf mines/tunnels (Figure 1). After collecting specimens, we’ve confirmed the very hungry and tiny culprit is the caterpillar of the tomato pinworm (Keiferia[Read More…]
Carrots are a wonderfully diverse crop with a wide array of varieties available to growers. Within this diversity lies the potential for identifying varieties that have higher natural resistance to particular kinds of insect pests. Although it is not a major pest in Indiana, the carrot weevil (Listronotus oregonensis) (Figure 1A) is a serious pest[Read More…]
After weeks of successive trap catches being empty or in the single digits, we have seen a dramatic increase in the last couple of days in the number of corn earworm moths captured in our pheromone traps throughout the state. At multiple locations catches jumped from near nothing to hundreds of individuals in a single[Read More…]
This is our second year scouting CBD hemp to learn more about the insect communities occurring on these plants throughout the season and ‘who’ the potential pest insects might be! This year we had the opportunity to scout CBD hemp plants grown both in the field and in a high tunnel environment (Figure 1). Since[Read More…]
We were all hoping it would happen later, but unfortunately, the spotted lanternfly (SLF) (Lycorma delicatula) (Figure 1), an invasive planthopper with a piercing-sucking feeding strategy, was officially detected in Vevay, Indiana (Switzerland County) for the first time in July 2021. You can see pictures and read more about the detection at the Indiana Department[Read More…]
Sometimes choosing the right product to manage a particular pest can be a daunting and risky task, especially when crops are close to harvest and an imposing outbreak sneaks up on you. One such pest that is sneaky are two-spotted spider mites (Tetranychus urticae; Figure 1). This microscopic pest can hang out in the crop[Read More…]
A quick glance at my vegetable garden on Thursday, June 17, revealed a lonely Japanese beetle… I dutifully squished it! This does indicate that emergence is beginning in west central Indiana. Hatch has undoubtedly been going for several days in southern counties, whereas, northern counties will soon be graced with their presence. Oh joy! Japanese[Read More…]
Unfortunately, pests don’t know when to take the day off. Even though we have bees in the field and watermelons reaching peak bloom, we still need to watch out for pest infestation and disease outbreaks. First and foremost, scouting fields to monitor pests will ensure that infestations never reach high enough populations to threaten yield.[Read More…]
For some, we may often forget about the pesky squash vine borer until it’s too late. This pest of cucurbit crops tends to be sporadic in our region; you are either battling it every year or it hardly makes an appearance. And, unfortunately, our urban farmers tend to get hammered. While it is not so[Read More…]
