BIOATTRACT® Goes Commercial |
|
BioAttract is an attractant feeding stimulant product designed for control of large moth pests such native budworm (Helicoverpa punctigera), Cotton bollworm (Helicoverpa armigera) , cutworms (Agrotis spp.), loopers (Plusia, Chrysodeixis and related) and armyworms (Mythimna, Leucania, Persectania, Spodoptera and related).What these species have in common is the ability to fly large distances (which rules out mating disruption as a viable strategy) and a strong drive to find nectar sources. Typically, the long distance flights are done by immature females which have not completed the development of their ovaries. This happens after migration when they find nectar in crop flowers, weeds or wherever. Without a nectar feed the moths can lay only about 500 eggs but with a good dose of energy from the sugar in nectar, they can lay 1500 eggs. Consequently, there is a very strong drive for female moths to find nectar.
Some years ago, the United States Department of Agriculture Agricultural Research Service identified a group of floral volatiles which together were particularly attractive for Heliothis and other nectar feeding moths. Bioglobal has further refined the attractant blend and incorporated it into a controlled release formulation which is BioAttract.
Farmers add a small quantity of insecticide to the product prior to use of the product. As moths actively seek out BioAttract, the product is applied in bands around crop perimeters and at 100 metre intervals across fields. 99% of the crop receives no insecticide at all and farmers can control even very large pest populations with only 1% of the insecticide used in a normal cover spray. The product has some rain resistance and an effective field life of about 10 days.
In order to get the desired results, BioAttract is applied at the first sign of an invasion of moths into the crop. Heliothis flights can be monitored using pheromone traps and crop scouting for adult moths. Bioglobal is also working on a trapping system that will allow farmers to detect flights of armyworms.
