European corn borer (ECB) moths have been captured at more locations over the past week, but numbers remain very low, and feeding has rarely risen to detectable levels. ECB population maps will resume if second flight catches rise to high enough numbers.
The highest nightly blacklight trap catches of ECB for the week ending 08/11/21 are as follows:
| Califon 1 | Jones Island 1 | South Branch 1 |
| Crosswicks 1 | Medford 1 | |
| Downer 1 | New Egypt 1 |

NOTE: Cucurbit downy mildew (CDM) was detected on cucumbers at the Snyder Research and Extension Farm in Hunterdon County on Wednesday 07/07/21. No other cucurbit crops exhibited signs of infection. Growers should assume that CDM races that infect cucumber and possibly muskmelons are now active in ALL parts of the state. See the Pumpkin and Winter Squash section below for more information.
Sweet Corn
European corn borer (ECB) moth catches continue to be extremely low around the state. The few remaining infestations are in pre-tassel stage sweet corn. Whorl is largely un-infested with ECB at this time. ECB population maps will resume if second flight catches rise to high enough numbers.
The highest nightly trap catches of ECB for the week ending 07/07/21 are as follows:
| Blairstown 1 |
| Downer 1 |
| East Vineland 1 |
