I called Dr. McBug, and because I am not large scale, the Spring Tiphia wasp was a lot over my budget. He told me that we probably had the wasp up in the Tulip Poplars and on the Forsythias, however they don't fly far and the Tulip Poplars are 50' in the air - so that is where the wasps are. I immediately started planting forsythia. Maybe I can coax 'em down into the orchard! If you call Dr. McBug, he will probably also tell you that the Hb Nematode may help with controlling the beetle. In Japan, there is not much problem with the JB, but they have over 65 things that eat the JB! We have few. I understand Sevin works on the beetle, but am loath to take that up, because now I have several million nematodes depending on me to treat them right!

"What really is needed is a comprehensive regional approach to the Japanese Beatle wich involves the release of a fly and the Spring Tiphia Wasp wich lays its eggs in the larva of the japanese beatle. Each Spring Tiphia Wasp that is born represents a dead Japanese Beatle. The Wasp eats aphids when not laying eggs in JB Grubs. Food plants that support aphid growth must be present. The best thing about them is that they can fly out for miles and search out maternity hosts that die as a result as far as any Japanese Beatles range that could make it to your plants. They will also breed and increase their range. Richard C. McDonald, Ph.D. Says, - "With adequate food plants nearby (this is a must), and no toxic chemicals inthe ground, the Spring Tiphia can parasitize up to 2/3rds of a population of Japanese beetle or Oriental beetle grubs. Its period of activity ranges from April through June, depending upon the location. A well-fed wasp can lay over 70 to 120 eggs during her lifespan of 6 to 8 weeks. The spring Tiphia was considered by USDA researchers to be the most effective parasitoid of the Japanese beetle throughout its range." - The USDA released these wasps on the east coast decades ago but has completely abandoned the midwest. I think that the Japanese Beatle should be treated as a National Disaster and that Biological Warfare should be declared upon these foriegn invaders!
