Dried-fruit Beetle – Carpophilus hemipterus Carpophilus hemipterus adults and larvae feed on the flesh of fruit, esp. those contaminated by fungi and yeasts(4). The chemical basis underlying orientation to fruit and fungal odors was investigated for the dried-fruit beetle,Carpophilus hemipterus (L.). In wind-tunnel .

Sap beetle Carpophilus spp. Adult Carpophilus fumatus Boheman, collected on strawberry. Carpophilus beetle entry point in nectarine. Australian Pesticides and Veterinary Medicine Authority. Picnic beetles become active on warm days in late winter or early spring. Management Back to Top Sap beetles are considered minor pests of field and sweet corn and strawberries in Florida.
Insecticides registered for the control of driedfruit beetles in deciduous fruit tree orchards in Western Australia are listed in the Pome and summer fruit orchard spray guiderefer also to Infopest for information on chemical registrations.
For details on the trapping system, consult the Australian Pesticides and Veterinary Medicine Authority website. They enter the fruit either near the stem or through splits and sites of mechanical damage. The adult beetles are also a major vector of the fungal diseases, including brown rot Monilinia spp. Lifecycle of the the carpophilus beetle.
Dried Fruit Beetle (Carpophilus)-pest of stone fruit | Agriculture and Food
Observations on the biology and control of the dusky sap beetle in Illinois. More than half of the genera are cosmopolitan or nearly so Parsons Influence of food on development, survival, fecundity, longevity and sex ratio of Glischrochilus quadrisignatus Coleoptera: In the Florida study Potter Epuraea luteolus apparently feeds on decomposing fruit material.
Upcoming Events Discussioninsects and people from the BugGuide Gathering in VirginiaJuly Photos of insects and people from the gathering in WisconsinJuly Photos of insects and people from the gathering in VirginiaJune Picnic beetles, Glischrochilus quadrisignatus and Glischrochilus fasciatusare about 6.
Pupae are white, turning cream colored and later tan before adult emergence.
Eggs are often laid on the silk of corn and have a generation time of 2—4 days. Scientists are studying ways to move infected sap beetles into areas where the nematode does not exist so the nematode can be used as a biological control agent. Antennal grooves are usually present. In wind-tunnel bioassays of walking and flight response from 1.
Photograph by James F. Bugguide is hosted by: Maize sap beetles appear to be well adapted for vectoring mycotoxigenic fungi, including species in the genera AspergillusPenicillium and Fusarium.
Male longevity was reported by Sanford to be Nitidulidae populations in central Illinois cornfield-oak woodland habitat and potential influence of weather patterns. They caepophilus active around April or early May and are attracted to decomposing plant material or wounds in trees.
Baits using such material can be effective in trapping and monitoring sap beetle populations, and hence determine funggi treatment is necessary.
An attract and kill strategy fungj draws beetles out of the block is an effective alternative to cover sprays. Damage Back to Top Both direct and indirect damage can be caused by Carpophilus spp. Females can oviposit up to eggs in their lifetime. The odor from yeast on agar had fewer components, and these were present at lower concentrations than the odors of either banana substrate. This may last 9—10 days before reemerging, but it can be longer if overwintering becomes necessary.
The species mentioned above are characterized by their affiliation with a specific host or group of related hosts.
Species Carpophilus hemipterus – Dried-fruit Beetle –
Like other sap beetles, fruit secretions are the primary food source, but they will also consume fungi, decomposing fruit and even pollen. Two generations were carpopuilus in Ohio the second occurring on field corn left in the field after harvest Dowd and Nelson Such material should be destroyed, or, if buried, should be buried deep below the soil.
They fly to fields of ripening or damaged berries, tree wounds and corn.
Carpophilus beetles are strong fliers, able to travel several kilometres in search of hosts, and as such they contribute to the spread of brown rot from orchard to orchard. In the tropics, multiple generations may occur especially if there is available food material throughout the year.
One species, Carpophilus davidsoniis particularly aggressive in stone fruit and carppphilus. Agricultural pest species from the genera CarpophilusStelidotaand Glischrochilus are distributed throughout Florida.
Okumura and Savage Potter found that Epuraea luteolus has a more rapid development and mature larval development is attained after 11 days when placed in culture. In the field, common on overripe fruit; indoors, in all kinds of dried fruit and much less frequently in cereals, oilseed, and their derivatives 4 ; also under rotten logs, oak wilt mycelial mats 3. Mature larvae emerge from the fruit and pupate in the ground. A long lived species, the dusky sap beetle can live as an adult for up to days.
The elytra or wing covers are entire sometimes shortened to expose two or fung abdominal segments. Hibernation sites are similar to that of Carpophilus lugubris. Observations on the biology and control of Glischrochilus quadrisignatus.
Driedfruit beetles are introduced pests in Australia and they have no known natural enemies to limit their abundance. Sap beetle feeding on strawberry.
Adult Glischrochilus quadrisignatus Saya picnic beetle. The study however did not demonstrate the economic impact if any on strawberry fruit production.
