| Comments |
Preventive releases may need to be made weekly instead of bi-wkly if the crop is a “whitefly magnet.” |

Other Biocontrols
Release rates Fly Parasitoids
| Release Rates for Fly Parasitoids — Legend | Menu |
| Classification |
Release information |
| Animals |
Multiply total livestock weight by 1.6 = number parasitoids needed for release. |
| Manure |
Add 65-85 parasitoids per cubic yard of breeding medium. |
| Compost |
Add 45-60 parasitoids per cubic yard of breeding medium. |
| Extreme |
If conditions are fly-intensive or if there is a lot of wetness, try mulitplying by 1.8-2.0. Poultry and cattle may apply. |
| Comments |
Releases should be made bi-weekly throughout the fly season. Use with traps for adults and practice sound manure management. |
Release rates Tenodera
| Release Rates for Tenodera — Legend | Menu |
| Mantids are considered a novelty and not recommended for pest control. That said, one case will yield 50-400 nymphs. Enjoy their use. If you hatch out an egg case of mantids and put the nymphs in a 500 square foot garden (one with cover; clover works well), you should be able to retain one mantid for the season, at least until adulthood when it develop wings and takes off, but that’ll be late in the season. If you’re observant, you should be able to readily locate this solitary mantid on any given day. The same is true of a greenhouse or interiorscape environment. |
Release rates Pediobius

Release information |
| Prevent |
1-2/yd, weekly, as needed. |
| Low |
2-3/yd, weekly, 1-2 times. |
| Med |
3-4/yd, weekly, 1-2 times. |
| High |
4-5/yd, weekly, 2-3 times. |
| Maint |
1-2/yd, tri-wkly, indef. |
| Garden |
3-5% of rates listed. |
| Acre + |
2-3% of rates listed. |
| Comments |
Timing is critical. Order as soon as you see the bean beetle’s eggs on your plants. |
Release rates Podisus
| Release Rates for Podisus — Legend | Menu |
| Classification |
Release information |
| Prevent |
Not suitable for use in this rate class. |
| Low |
1-2/yd, mnthly, 1-2 times. |
| Med |
2-3/yd, bi-wkly, 2-3 times. |
| High |
4-5/yd, bi-wkly, 2-3 times. |
| Maint |
1-2/yd, mnthly, indef. |
| Garden |
30-45% of rates listed. |
| Acre + |
20-35% of rates listed. |
| Comments |
May be useful for several pests, but try them and the rates shown experimentally until more data is collected. |
Release rates Pseudoscymnus
| Release Rates for Pseudoscymnus — Legend | Menu |
| Use 500 beetles for up to three acres of hemlocks or up to six acres of a mixed planting consisting of no more than the equivelent of three acres of hemlocks. You can get away with doing this once and the population should be self-servicing from then on. This is experimental until more data is collected. |
Release rates Bombus
| Release Rates for Bombus — Legend | Menu |
| Classification |
Release information |
| General |
Hives typically come in three sizes typical size — “A,” “B,” and “C” — as an industry standard. There are two other special products in addition. Here’s the breakdown: |
| Class “A” |
This hive treats 10-15,000 square feet for 12-14 weeks. |
| Class “B” |
This hive treats 5-10,000 square feet for 10-12 weeks. |
| Class “C” |
This hive treats up to 5,000 square feet for 4-5 weeks. |
| “Quads” |
This large outdoor hive treats up to 2 acres on its own or up to 4 acres supplementarily. |
| “Drones” |
Use drone-only bee units — not supplied as a hive and they don’t sting — for isolates of 2-20 plants or more. |
| Comments |
Greenhouse crop volume should be considered as it is done when figuring for other biocontrol agents. |
