Eggs are deposited singly beneath the surface anthnomus the bud or pod. Journal of Chemical Ecology Host relations are described by Patrock and Schuster Curculionidaeen Puerto Rico.
First instars measure about 1 mm in length range 0. Euugenii adult emerges from the pupal case three to four days after being formed.
The figure for third instar development time contains a prepupal period of about 4. Larvae are aggressive, with only a single larva surviving within a bud, though more than one can occur within larger fruit.
There are few cultural practices that significantly affect pepper weevil damage. Gordon R, Armstrong AM. Journal of Agriculture, University of Puerto Rico Coleoptera – Diptera – Hymenoptera.
Insect Management Guide for tomatoes, peppers and eggplant. CapineraUniversity of Florida. Adult Cuban pepper weevil, Faustinus cubae Bohemanlateral view.
Fruit drop is very eugenli, and is perhaps the most obvious sign of infestation. Both eugsnii and larval feeding anhonomus bud drop. Adult population estimates are best obtained by visual examination and yellow sticky traps Segarra-Carmona and Pantoja a. Males produce an aggregation pheromone that attracts both sexes Eller et al. If visual monitoring is preferred, terminal bud sampling is effective, although more beetles are present in the morning than evening Riley et al.
Choate, University of Florida. Females deposit eggs at a rate of about five to seven eggs per day, anghonomus fecundity averages eggs but is nearly in some individuals. Other descriptions are by Goff and Wilson and Gordon and Armstrong Second instars measure about 1. The appearance of adults is distinct, however, with the body of the Faustinus cubae weevil bearing numerous rough or raised areas, and a considerable amount of brown coloration.
Photograph by John L. Pepper weevil populations persist only where food plants are available throughout the year, largely limiting its economic pest status to the southernmost state in the USA.
The pupal cell is brittle and found within the blossom or fruit.
The adults are long-lived and produce overlapping generations, so it is difficult to ascertain generation number accurately. The blackish beetle is oval in shape and varies from 2. Puncture of peppers by pepper weevil allows penetration of the fungus Alternaria alternataan otherwise weak pathogen, and extensive fungal growth within the pepper fruit. Pepper weevil adult response to colored sticky traps in pepper fields.
Because transplants are shipped northward each spring, however, pepper weevil sometimes occurs in more northern locations. The thorax and elytra are mostly covered with small scales.

Segarra-Carmona and Pantoja b estimated that economic damage commences with adult populations of 0. In the absence of pepper blossom and fruit, adults feed on leaves and stem material of pepper, but cause no significant damage by these habits. Adult Cuban pepper weevil, Faustinus cubae Bohemandorsal view. Sanitation can be important, if it can be implemented on an appropriate scale.
A sequential sampling protocol was developed by Segarra-Carmona and Pantoja b. Larva of the Cuban pepper weevil, Faustinus cubae Boheman.
Curculionidae in bell peppers. A complete generation requires 20 to 30 days, depending on weather. Notice larva in stalk at upper left.
Sampling and eugsnii of pepper weevil Coleoptera: Pepper weevil was first observed in Hawaii in and in Puerto Rico in Pteromalidae and Bracon mellitor Say Hymenoptera: The eggs are white when first deposited, but soon turn yellow.
This weevil, though a serious pest in Brazil and other areas of Latin America, is still quite limited in distribution in the United Aanthonomus. The color is dark mahogany to nearly black. The distribution of weevils is aggregated.
