Leptomastix dactylopii
Release these parasitoids at sundown the day of receipt. To release, open the jar or bottle in the crop and allow the emerged wasps to fly out on their own as you walk among the plants (or tap out the pupae). You can speed up their exit by gently tapping them out. If they begin to exit too quickly or if dispersal control is not manageable (which may happen when they’re warm), re-secure the cap between release points or try removing the filter paper (if present) then re-secure the cap, then release the wasps through the lid’s opening. Concentrate the bulk of them at release points on or near the most heavily infested plants. For any wasps that will not readily come out of the jar or bottle, simply tuck the perching material inside the jar (for jar releases only) into the foliage of a plant, preferably one with a heavier pest population. Use this technique for tree releases, and try to get the perching material into the canopy. Do not store L. dactylopii adult wasps in the jar for more than 6 hours. Hold at a slightly humid 55-65°F.

Harmonia axyridis
This organism is no longer commercially available from any source! Release these beetles at sundown the day of receipt (after full dark is highly recommended for H. axyridis adults). Mist the foliage of the plants to be treated just prior to release (for releasing adults only). To release, open the jar or bottle in the crop and gently tap out the beetles-or their larvae, which come in a tray with popcorn-directly onto the foliage of the infested plants, or evenly throughout the crop if the infestation is widespread. If the adult beetles begin to exit too quickly or dispersal control is not manageable (which may happen when they’re warm), try removing the filter paper then re-securing the cap or lid, then release the beetles through the cap’s or lid’s opening. Concentrate the bulk of them at release points on or near the most heavily infested plants. For any that will not readily come out of the jar, simply tuck the perching material inside the jar into the foliage of a plant, preferably one with a heavy pest population. Use this technique for tree releases, and try to get the perching material into the canopy. Supplying these beetles with certain plantings (flowering, pollen producing plants), at or near the release site, may increase their egg laying activity. Do not store H. axyridis adult beetles in the bottle for more than 24 hours. Hold at a humid 45-50°F (fridge best).

For any wasps that will not readily come out of the jar or bottle, simply tuck the perching material inside the jar (for jar releases only) into the foliage of a plant, preferably one with a heavier pest population. Use this technique for tree releases, and try to get the perching material into the canopy. Do not store M. helvolus adult wasps in the jar for more than 8 hours. Hold at a slightly humid 55-60°F.

Rhyzobius lophanthae
Release these beetles at sundown the day of receipt. Mist the foliage of the plants to be treated just prior to release (for releasing adults only). To release, open the jar or bottle in the crop and gently tap out the beetles — or their larvae, which come in a tray with popcorn — directly onto the foliage of the infested plants, or evenly throughout the crop if the infestation is widespread. If the adult beetles begin to exit too quickly or dispersal control is not manageable (which may happen when they’re warm), try removing the filter paper then re-securing the cap or lid, then release the beetles through the cap’s or lid’s opening. Concentrate the bulk of them at release points on or near the most heavily infested plants. For any that will not readily come out of the jar, simply tuck the perching material inside the jar into the foliage of a plant, preferably one with a heavy pest population. Use this technique for tree releases, and try to get the perching material into the canopy. Supplying these beetles with certain plantings (flowering, pollen producing plants), at or near the release site, may increase their egg laying activity. Do not store R. lophanthae adult beetles in the jar for more than 12 hours. Hold at a humid 55-65°F.

Cybocephalus nipponicus
Release these beetles at sundown the day of receipt. Mist the foliage of the plants to be treated just prior to release (for releasing adults only). To release, open the jar or bottle in the crop and gently tap out the beetles directly onto the foliage of the infested plants, or evenly throughout the crop if the infestation is widespread.

Use this technique for tree releases, and try to get the perching material into the canopy. Supplying these beetles with certain plantings (flowering, pollen producing plants), at or near the release site, may increase their egg laying activity. Do not store the adult beetles in the jar for more than 8 hours. Hold at a moderately humid 55-60°F.
