Growing strawberries under high tunnels can extend the harvest season, provide protection against rain, frost, and disease, and improve overall yield and fruit marketability. Pest pressure, however, can be higher on protected culture strawberry compared to the open field. This is especially true for small, soft-bodied pests such as spider mites, aphids, and thrips. Even[Read More…]

After a long cold winter under protection, nothing signals spring like the first blooms on strawberry. ‘Tis the season in our high tunnels and thus time to provide a few reminders/updates on how to protect the development of these early fruits from insect pests.

Insects provide an important pollination service in many crops including strawberry. Although strawberry flowers can self-pollinate without insects, it is well known that supplemental pollination by insects can result in better formed and larger fruit. Therefore, pollination services in strawberry affects both quantity (berry size) and quality (berry shape) of yield. By evaluating strawberry fruit[Read More…]
In the strawberry benchtop system in the greenhouses at Southwest Purdue Ag Center (SWPAC), we have been experiencing infestations in red berries of a small, clear larvae with a black head capsule. The larvae are often found in clusters on a single fruit and were difficult for us to identify. We encountered them in early[Read More…]
Aphids have been a particularly challenging pest to get under control in our high tunnel strawberries this year. They quickly colonized the strawberries we had growing all winter and took off as the weather warmed (Fig. 1). In my first attempt to knock them back I introduced 2,000 lacewing larvae (22-Apr), too little too late.[Read More…]
This winter-spring has been my first excursion into growing strawberries in a high tunnel. It didn’t take much for our own Wenjing Guan to convince me to plant some; who doesn’t love to eat fresh strawberries? We planted them back in October and I just peeked at them every couple of weeks throughout the winter,[Read More…]
Recently we have received reports of swarms of hover flies (aka syrphid flies) around Indiana and wanted to take the opportunity to tell you a bit about this curious insect (Figure 1). Adult hover flies can sometimes be mistaken for bees or wasps, because they look a lot like them! Some people refer to hover[Read More…]
