Description

Adult Description: The Cuban Cockroach (Panchlora nivea) are 20-25mm in length, but on occasion can be as long as 50mm. Panchlora nivea are bright green in color with a yellow margin on the anterior portion of the elytra.

Larva Description: During the nymph stage P. nivea are black or dark brown in color, and takes about 100 days to mature and take on the appearance of the adult.

Host Plant: Panchlora nivea is known to infest banana trees and is not considered an indoor pest.

Ecological Threat

Panchlora nivea are considered a minimal pest due to its inability to develop and reproduce indoors. Outside they can be considered a pest due to high density in areas where firewood or leaf piles are kept. Currently the only known agricultural threat is to banana plants when populations increases to high densities.

Biology

Female P. nivea give birth to an average of 30 nymphs at one time. The eggs develop within the abdominal cavity of the female Cuban Cockroach which is large enough for the eggs to undergo postnatal development, and emerge in the nymph stage. The eggs develop within the female for about 2 months.

History

It is believed that P. nivea spread from Cuba to the United States with shipments of bananas by mistake. The Cuban Cockroach can also be purchased as a pet in the United States and has spread through incidental escapes.

Native Origin

Cuba

Current Location

U.S. Habitat: Panchlora nivea is not usually found indoors unless kept as a pet. Outside the Cuban Cockroach can be found in trees, shrubs, herbaceous plants, piles of lumber, piles of leaves, and mulch.

U.S. Present: Currently, the Cuban Cockroach is established in the Southern United States near the gulf, but most abundant in Florida.

Texas: Eastern Texas from the gulf coast to Central Texas

Management

The Cuban Cockroach is attracted to light and active during the night hours, therefore keeping outside lights off when possible prevents further establishment of the Cuban Cockroach. Also, P. nivea establishment can be discouraged by scattering wood piles and disposing of leaf piles to remove the ideal habitat for this cockroach.
