Primarily Mealybug species from the following families.
Cryptolaemus montrouzieri attacks the citrus mealybug and other closely related mealybug species as well as several soft scales, including hemispherical scale and its relatives. It is considered an important predator of the citrus and long-tailed mealybugs in greenhouses and interior plantscapes and efficiently controls the pink hibiscus mealybug.
It has been well noted in field studies that BioCryptolaemus and BioAnagyrus complement each other in the field allowing for a much faster control of the target pests.
Cryptolaemus montrouzieri preys on mealybugs and soft scale insects in
vegetables, flowers, ornamentals, citrus, vineyards, field and fruit
crops. Mealybugs and soft scales infest many crops including: guava,
mango, grapevine, citrus, coffee, ornamental plants, mulberry, aloes, prickly pears and many others.
Cryptolaemus montrouzieri is a small dark brown beetle, that has the destinct shape of a ladybug, the colouring however is muted. , about 4 mm long with an orange head, prothorax, wing tips and abdomen. Cryptolaemus montrouzieri eggs are yellow and often laid in mealybug aggregations. The life cycle of BioCryptolaemus takes about 2 months from start to finish. Both adults and larvae (which mimic mealybugs) actively predate on a wide variety of scale insects.
- BioCryptolaemus is packed in paper bags containing 50 adult beetles. Honey-soaked paper serves as food for the adult beetles in the product package.
- The predators are released by opening the package and placing the adult beetles adjacent to mealybug-infested spots.
- If necessary, BioCryptolaemus can be stored for 24 hours at a temperature of 10-12°C from the moment of arrival until release. The product should never be frozen.
- BioCryptolaemus is compatible with BioGrow products sold by Livingseeds
- BioCryptolaemus is shipped in isolated styrofoam packages chilled with icepacks. This packaging must be kept intact until it reaches the end-user. When applied, the boxes should be taken from the shipment package one by one and the predators should be released immediately.
- About 3 weeks to one month following the predatory beetles’ release (depending upon temperature), their larval offspring are clearly seen within the mealybug-infested spot. Remains of dead mealybugs, preyed upon by BioCryptolaemus, are also visible.
- The subsequent established generations of the predatory beetle will effectively control the mealybugs in the long run. Cryptolaemus montrouzieri and the mealybug parasitoid Anagyrus pseudococci (BioAnagyrus) complement each other: The former seeks dense populations of mealybug pests. Hence it is effective in mealybug hotspots. The latter is a superior searcher for mealybugs at low infestation rate. Therefore it is best used under initial/scarce infestation by mealybugs.
- The predatory beetle does not discriminate between non-parasitized mealybugs and those inhabited by early stages of the parasitic wasp. Consequently, it may consume early-parasitized mealybugs. However, once the parasitized mealybug mummifies, the predatory beetle avoids it completely. Thus the two natural enemies may co-exist in the same habitat and establish long-lasting control of mealybugs.
- The rate and frequency of BioCryptolaemus release may differ from one host plant and/or habitat to another. Introduction rate should be determined according to the nature of the crop (open field or protected) and according to the rate of mealybug infestation.
- If ants are present at the mealybug hotspots, they must be destroyed. Ants encourage honeydew secretion by the mealybugs, transferring them from one place to another while protecting them vigorously from the predators.
- A mix of 50:50 Borax and Sugar moistened with a bit of water will help to control the ants. Please put this mix down a week prior to releasing BioCryptolaemus.
