Diglyphus isaea 2mm mini-wasps are best used for preventing the establishment of several leaf miner species, and can tackle minor infestations. If established, they can adequately protect a crop throughout the season. Shipped as pre-hatched, pre-fed adults. Ship when leaf miners are first seen, in warmer area. They do best in warmer conditions. Caution using yellow, sticky traps with these wasps.
Optimum performance: 75-90° F, 80% relative humidity
Release rates: 0.25-.5/10 sq ft. It is recommended to make 2 introductions, one week apart.
Biological Pest Control Agents
Biocontrols are an effective tool to growers in just about any situation. Bear in mind that when using biocontrols, a new set
of rules must be followed:
1. Growers must reduce the amounts of pesticides used, and in most cases, either substitute what’s on hand or, better yet, simply discontinue the use of pesticides entirely. (The outcome of this is typically a major reduction in applicator labor.)
2. Multiple releases of biocontrols are necessary in nearly every case, like most sprays, and should be thought of as a part of an overall program or strategy.
3. All live biocontrols are shipped next day air, from the grower, therefore freight costs can be high. Detailed short-term storage, handling and release instructions are included with every order.
Orders must be placed by Wednesday 12pm CST to get shipment by the following week.
