This approach could be considered where driedfruit beetles are a consistent pest. Photograph by James F. Being capable of attacking undamaged fruits and vegetables makes the Carpophilus genus a large threat to economic crops. The newly emerged females of the overwintering generation deposit eggs on or near decomposing plant material such as corn ears on or in the soil.

Adult Carpophilus are small at around 3mm long, oblong shaped beetles with short wing covers such that the end of the abdomen is not covered and have clubbed antennae. American Beetles, Volume II: Good hygiene is the most important aspect in the management of this pest.

Insecticides do not give long-term protection. The adults feed on corn plant residues left in the field after harvest.

sap beetles of Florida – Nitidulidae

Thus, our results suggest that this generalist insect herbivore locates its hosts by a long-range response to a variety of blends of common fruit volatiles, whose concentrations are enhanced by fungi. Information on sap beetle biology is known primarily from studies done in the north central United States, principally Illinois and Ohio where Carpophilus spp.


They fly to carpophilux of ripening or damaged berries, tree wounds and corn. Retrieved from ” https: This may last 9—10 days before reemerging, but it can be longer if overwintering becomes necessary. Sap beetles are often considered minor pests but the presence of large numbers of sap beetles on a host plant can prove economic in terms of crop damage caused by the feeding beetles, but impact on crop value is primarily due to the contamination of products ready for sale by adults and larvae.

At least 12 species of carpophilus beetle occur in Australia, and many more species are recognised as pests worldwide. One such refuge is the bottom of bee creates, which are often closely located to crops. If you need expert professional advice, contact your local extension office. These csrpophilus are more resistant to corn earworms and the beetle itself and therefore are less likely to be infested by sap beetles. Adult left and larva right of the large sap beetle picnic beetle, nitidulidLobiopa insularis Fung.

More than half of the genera are cosmopolitan or nearly so Parsons Pupa of Carpophilus lugubris Murray, the dusky sap beetle. The prosternum has a process produced between the front coxae.

They have short wing covers and clubbed antennae. However, the beetles are not restricted in their host range.

Carpophilus lugubris

Pre-oviposition period, egg production and mortality of six species of Hibernating sap beetles Coleoptera: Damage Back to Top Both direct and indirect damage can be carpiphilus by Carpophilus spp. Abdominal segment VIII of males is heavily sclerotized, well raised and large.

Their host range may include tree and small fruits such as peaches, figs, blueberries, raspberries and strawberries, pineapples, melons, field and sweet corn, stored corn and dried fruit products.

Nuessly, University of Florida. Nitidulidae and development of an environmentally friendly method of crop protection. Sap beetles have demonstrated a wide range of feeding habits with the majority of the group being primarily saprophagous and mycetophagous Parsons Agricultural Research 42 7. They also invaded fields that had corn stalks damaged by the European corn borer.

Handbook of vegetable pests. As they crawl through damaged fruit, the spores of brown rot stick to their bodies and are spread through the tree canopy and from orchard to orchard.

Larva of Lobiopa insularis Cast. They become active around April or early May and are attracted to decomposing plant material or wounds in trees. When presented in a two-choice bioassay, the yeast-inoculated banana attracted approximately twice as many beetles as did the aseptic banana.

Dowd and Nelson reported early migration peaks in both raspberry and corn at the end of the strawberry season which may indicate that these sites are utilized by the beetle for over-wintering. Stone fruit can be attacked on the tree, beetles burrow into the fruit, particularly near the stem end suture line. Driedfruit beetles are strong fliers and can travel several kilometres in search of hosts.
