Maconellicoccus hirsutus (Hemiptera, Pseudococcidae) - pink or hibiscus mealybug

Why M. hirsutus came to our attention because of its current spread in the Caribbean.

Where Originally present in Africa, Asia and Oceania. It was introduced in 1994 in Grenada, it then spread in Trinidad (1995), St Kitts & Nevis (1995), Netherlands Antilles (Sint Maartin, 1996), British Virgin islands (1997), Guyana (1997), Netherlands Antilles (Curaçao, Sint Eustatius; 1997), United States Virgin islands (St Thomas, 1997), St Vincent and the Grenadines (1997), Anguilla (unconfirmed), Guadeloupe (1998), United States Virgin islands (St Croix, St John; 1998), Puerto Rico (1998), Barbade (2000), Bahamas (New Providence, 2000), Antigua & Barbuda (only in Antigua, 2001), Dominica (2001), French Guiana, Suriname (2001), Venezuela. It is also reported in British Virgin islands (Tortolla), Monserrat and Netherlands Antilles (Aruba).

In USA, found in 1999, in the south of California (El Centro, Calexico), and in 2002 in Florida. It also occurs in Mexico, in Baja California (Mexicali) and in Sonora (San Luis Rio Colorado).

On which plants Polyphagous: ornamentals, vegetables, forest and fruit trees.

Damage It feeds on sap. Dense colonies of woolly aspect are visible on attacked plants which rapidly decline and show spectacular deformations (probably due to a toxin in the mealybug saliva).

Pathway Ornamental plants for planting (cut flowers? fruits?) from infested countries.

Possible risks Polyphagous pest, spreading very rapidly in the Caribbean. Tropical species, the risk is probably limited to glasshouse crops.
