The predaceous coccinellid Cryptolaemus montrouzieri Mulsant (the mealybug destroyer) (Coleoptera: Coccinellidae) has been used successfully on chrysanthemum with releases at the rate of one adult predator for every two plants.
Which laboratory host is used for rearing Cryptolaemus Montrouzieri?
montrouzieri with the aid of two mealybug host species; Planococcus minor and Pseudococcus viburni, under laboratory conditions. The predator was reared on P. minor and P. viburni, using two substrates; local pumpkin (Cucurbita moschata) and Malaysian pumpkin (Cucurbita maxima).
What do Cryptolaemus eat?
Adult beetles and young larvae feed on mealybug eggs and young stages. Large cryptolaemus larvae can consume adult mealybugs. Cryptolaemus will also eat a range of scale insect species.
Do Cryptolaemus montrouzieri fly?
Although adults and young larvae prefer to feed on mealybug eggs, older larvae will attack any mealybug stage. Adults can fly and cover large areas to search for food.
How do you release Cryptolaemus?
At release Cryptolaemus are supplied in punnets containing a minimum of 40 beetles or in tubs of 500 beetles. The container should be opened and the beetles dislodged by lightly tapping onto plant foliage near mealybug infestations.

Why was the Cryptolaemus montrouzieri introduced to the United States?
This beetle was imported into the United States in 1891 from Australia by one of the early biological control pioneers, Albert Koebele, to control citrus mealybug in California. Although C. montrouzieri initially devastated the citrus mealybug populations in citrus groves, it was unable to survive the winter except in coastal areas.
What kind of plants does Cryptolaemus montrouzieri attack?
C. montrouzieri attacks citrus and closely related mealybugs and some soft scales, including hemispherical scale and its relatives. It is considered an important predator of citrus and long-tailed mealybug in greenhouses and interior plantscapes and is being introduced in a biocontrol program in the West Indies to control pink hibiscus mealybug.
What makes a Cryptolaemus different from other Coccinellidae?
TS: Cryptolaemus montrouzieri Mulsant, 1853. Cryptolaemus is easily distinguished from all hairy Coccinellidae by its elongate prosternum, 10-segmented antenna, 3-segmented tarsi and complete, recurved postcoxal lines on abdomen.
How long does a Cryptolaemus montrouzieri live to pupate?
C. montrouzieri pupates in sheltered places on stems or on greenhouse structures. Adults emerge after 7-10 days and live four months. Four days after emerging, adult females begin to lay eggs, and the lifetime total may be as many as 400. Adults may live up to 2 months.
