Refined action threshold for pepper weevil adults Coleoptera: Larva of the pepper weevil, Anthonomus eugenii Cano.
The color is dark mahogany to nearly black. The anthonoums cell is brittle and found within the blossom or fruit. In some areas of central and south Florida another weevil is found affecting pepper, Faustinus cubae Bohemanwhich is often called the Cuban pepper weevil.
It can be a serious pest where it occurs.
Life Cycle and Description Back to Top A complete generation requires 20 to 30 days, depending on weather. Sequential sampling plan, yield loss components and economic thresholds for the pepper weevil, Anthonomus eugenii Cano Coleoptera: Aggregation pheromone for the pepper weevil, Anthonomus eugenii Cano Coleoptera: There are few cultural practices that significantly affect pepper weevil damage. It is now found across the southernmost United States from Florida to California.
Tropical Pest Management Oviposition may commence within two days of mating. Adult feeding punctures appear as dark specks on the fruit, and are not very damaging. Journal of Agriculture, University of Puerto Rico 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. The most complete treatment of pepper weevil biology is given by Elmore et al. 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.
The distribution of weevils is aggregated. Insecticidal suppression rugenii feasible, but insecticides vary considerably in effectiveness, and even in the presence of chemical insecticides some loss commonly occurs. Segarra-Carmona and Pantoja b estimated that economic damage commences with adult populations of 0.
Adult pepper weevil, Anthonomus eugenii Cano. The pupa resembles the adult in form, except that the wings are not fully developed and large setae are found on the prothorax and abdomen. Larvae are aggressive, with only a single larva surviving within a bud, though more than one can occur within larger fruit.
They are oval in shape and measure 0. Other descriptions are by Goff and Wilson and Gordon and Eutenii Anthinomus larva in stalk at upper left. The adult emerges from the pupal case three to four days after being formed.
Anthonomus eugenii –
Feeding, oviposition and development of the pepper weevil, Anthonomus eugenii Canoon selected species of Solanaceae. Females deposit eggs at a rate of about five to seven eggs per day, and fecundity averages eggs but is nearly in some individuals.
Curculionidae in bell peppers.
Rodiguez, University of Florida. Journal of Economic Entomology Similarly, a crop-free period, if accompanied by destruction of alternate hosts, can disrupt the life cycle. Fruit drop is very common, and is perhaps the most obvious sign of infestation. Thus, the larvae are easily confused.
The pupa is white eugenik first formed, but eventually becomes yellowish with brown eyes. Removal and destruction of fallen fruit, for example, will result in destruction of larvae and pupae. Puncture of peppers by pepper weevil allows penetration of the fungus Alternaria alternataan otherwise weak pathogen, and extensive fungal growth within the pepper fruit.

CapineraUniversity of Florida. If visual monitoring is preferred, terminal bud sampling is effective, although more beetles are present in the morning than evening Riley et al. Curculionidae on bell peppers.

Each femora bears a sharp tooth. Males produce an aggregation pheromone that attracts both sexes Eller et al. The blackish beetle is oval in shape and varies from 2.
