Sequential sampling plan, yield loss components and economic thresholds for the pepper weevil, Anthonomus eugenii Cano Coleoptera: In central Florida, adults are common from March until June, reflecting the antjonomus of peppers, but a few can be found throughout the year except in December and January.

The female creates an egg cavity with her mouthparts before eugenki the egg, and seals the puncture containing the egg with a light brown fluid that hardens and darkens.

Management Back to Top Sampling. 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. Insecticides are commonly applied to the foliage at short intervals once buds begin to form. Both adult and larval feeding causes bud drop. A clean, round hole marks the escape of the eguenii from the bud or fruit.

The thorax and elytra are mostly covered with small scales. Journal of Agriculture, University of Puerto Rico eygenii The figure for third instar development time contains a prepupal period of about 4.

Anthonomus eugenii –

Pepper weevil larvae develop only plants in the family Solanaceae. Because transplants are shipped northward each spring, however, pepper weevil sometimes occurs in more northern locations. The pupal cell is brittle and found eugenik the blossom or fruit.

Among vegetables, all varieties of pepper are susceptible to attack, tomatillo is a moderately susceptible host, and eggplant grown in proximity to pepper will sometimes be injured.

Refined action threshold for pepper weevil adults Coleoptera: The color is dark mahogany to nearly black. Oviposition occurs on plants in the genera Capsicum and Solanumbut feeding by adults extends to other Solanaceae such as PhysalisLycopersiconDaturaPetuniaand Nicotiana.

If visual monitoring is preferred, terminal bud sampling is effective, although more beetles are present in the morning than evening Riley et al. Action thresholds anthpnomus one adult per terminal buds Riley et al.

Pupa of the pepper weevil, Anthonomus eugenii Cano. Traps should be placed 10 to 60 cm above the soil; one sq cm trap captures as many weevils as are detected by inspecting 50 buds Riley and Schuster The larvae, which are similar in appearance to Anthonomus euginiibore in the stems of pepper and related plants, sometimes entering the fruit.

Larva of the Cuban pepper weevil, Faustinus cubae Boheman. They lack thoracic legs anthonkmus have few large hairs or bristles. Feeding begins immediately after emergence.
