[6] Early corn planting, in North Carolina, has show to reduce the number of damaged plants, as opposed to later planted crops. Eggs are milky white, small, about 1/25 inch long and not easily seen because they are laid within plant matter. [1] Related species act as vectors for disease, such as Oak Wilt. Sap beetles, especially the dusky sap beetle, Car-pophilus lugubris Murray, can also be major pests of sweet corn in different regions of the United States (Connell 1956a, Sandford and Luckmann 1963, Ta-maki et al. The University of Minnesota is an equal opportunity educator and employer. Following a report submitted by a beekeeper to Istituto Zooprofilattico Sperimentale delle Venezie, in Padua province (Borgoricco, Veneto, NE Italy), the authors discovered in April 2011 several specimens of the dusky sap beetle Carpophilus lugubrisMurray 1864 (Coleoptera, Nitidulidae) on the bottom board of some beehives. Use of pesticides is NOT very effective and is NOT recommended. The antennae of sap beetles have a club (knob) at the end. It is an agricultural pest of corn and tomato. The picnic beetle is also attracted to all types of over-ripe and damaged fruit. The corn (dusky) sap beetle (Carpophilus dimidiatus) is the most common of several species of small, flat, brown and black sap beetles that are present in most corn fields. Eggs are often laid on the silk of corn and have a generation time of 2–4 days.

Strawberries are the primary host for the strawberry sap beetle. 40SY001 They emerge in spring and lay eggs near fermenting and decaying plant material. Dusky sap beetle, a native insect, is the most important species. [1] C. lugubris is capable of feeding on undamaged fruits as well, corn being its primary food source. A related species is known to be parasitic to honey bee hives, in which they burrow into the hive and predate the larva. Larvae are small, (less than 1/4 inch long), white (pale yellow when mature) with a light brown head. Extension is expanding its online education and resources to adapt to COVID-19 restrictions. This may last 9–10 days before reemerging, but it can be longer if overwintering becomes necessary. [1] Larva and adults will often have overlapping niches, with the larva developing on the ears of the corn and eventually feeding on the kernels. Contact Info. John L. Capinera, in Handbook of Vegetable Pests, 2001. Foreign Grain Beetle: Ahasverus advena: Golden Spider Beetle: Niptus hololeucus: Granary Weevil: Sitophilus granarius: Hairy Fungus Beetle: Typhaea stercorea: Khapra Beetle: Trogoderma granarium: Common Name: [1] The egg, larva, pupa, and adult. 304 London NY 10016. ), strawberry sap beetle (Stelidota geminata), and a picnic beetle (Glischrochilus quadrisignatus) have become abundant coincident with the expansion in production of suitable crop hosts in Florida. [1] They can also act as vectors for fungi transfer to crop plants. Sap beetles are characterized by a rather short larval development and comparatively long-lived adults. [1] The larval stage begins feeding on corn kernels and undergoes 3-4 instars before entering the pupa stage. Picnic beetle adults are the largest (1/4-inch long), and are black with four orange-rust spots on the wing covers. Sap beetles live through the winter as adults in sites outside gardens. 1982). [1] The use of pheromones by Carpophilus species has influenced traps and lures to protect crops. CAUTION: Mention of a pesticide or use of a pesticide label is for educational purposes only. Dusky sap beetle (DSB) is a dark gray beetle, about 3/16" in length. Always follow the pesticide label directions attached to the pesticide container you are using.

In Utah, common, common species include the Corn Sap Beetle (Carpophilus dimidatus), Dusky Sap Beetle (Carpophilus lugubris), and Picnic Beetle (Glischrochilus quadrisgnatus). You may try bait trapping to reduce beetle populations. Sap beetles have demonstrated a wide range of feeding habits with the majority of the group being primarily saprophagous and mycetophagous (Parsons 1943). Remove any damaged, diseased and overripe fruits and vegetables from the garden at regular intervals. Sap beetles may be seen on strawberries that are also infected with a disease. [4] In Carpophilus sayi, pheromones from C. lugubris, are used to trick the species into believing a food source is nearby. dusky sap beetles (Carpophilus lugubris Murray) carrying the Kodiak Concentrate formula­ tion ofthe bacterium, Bacillus subtilis (Ehrenberg) Cohn. [3], Like the typical beetle life cycle, C. lugubris has four life stages. Both species have characteristic short wing covers and club-shaped antennae ( Figure 3 ). Picnic beetle adults are the largest (1/4-inch long), and are black with four orange-rust spots on the wing covers. It is found from the Atlantic to the Pacific, and south into Central and South America, but is most numerous in eastern and midwestern states. [1] Once exiting from the ground, the adult will use pheromones to locate a new food source and possible mating location. Trap buckets baited with whole wheat bread dough and over-ripe fruit outside the patch helps to reduce beetle numbers. Store Address.

Small yellowish or pinkish-white grubs may be found in ear tips along with adults. : Bulletin of the Museum of Comparative Zoology, vol. [2] Depressions can be see on each side of the pygidium, which is a characteristic of males. lugubris, the colonization ofmechanically damaged kernels by Sweet corn producers usually treat at this time to prevent infestation by corn earworm and other caterpillar pests, thereby suppressing sap beetles also (Harrison, 1962). ), strawberry sap beetle (Stelidota geminata) and a picnic beetle (Glischrochilus quadrisignatus) have become abundant coincident with the expansion in production of suitable crop hosts in Florida. They are more common on fruits and vegetables that have been damaged by another insect or infected with a disease. [2] Additionally, the genital capsule, which is quite distinct, can not be seen from an overhead view. Place traps that are more attractive than ripening fruit. Adults emerge from pupae in late June or early July. Suzanne Wold-Burkness, College of Food, Agriculture & Natural Resource Sciences; and Jeffrey Hahn, Extension entomologist. 48 Park Avenue, East 21st Street, Apt. Sap beetles of the genus Carpophilus are found throughout the United States and southern Canada. They can leave deep cavities in the berries, similar to the damage caused by slugs. These pesticides may kill existing beetles, but if fruit/vegetables are present, they cannot prevent additional sap beetles from moving into gardens. A long lived species, the dusky sap beetle can live as an adult for up to 300 days. Entomol.

The dusky sap beetle is similar in appearance except slightly larger, about 1/6 inch long, and dull black. These beetles prefer over-ripe fruit but also readily attack ripening fruit. Larvae are creamy white, worm-like and have a brown head capsule. [1] The species is long lived, so they will take up shelter in adverse environmental conditions. Dusky sap beetle adults are 1/8-inch long with short wing covers and are uniform dull black in color. They pass through three instars in 14 days, drop to the ground where pupal cells are formed a few inches below the soil surface. The larvae of sap beetles then feed on the undamaged kernels. [4] The ability to disperse via flight gives this genus great potential for disease transfer. Larvae are white with a brown head and three pairs of short legs near their head. Beetles appear at harvest and feed on damaged, overripe, or decomposing fruits and vegetables. Adults are small with club shaped-antennae. Sap beetles can injure fruits and vegetables.

A container of fermenting plant juices will also attract sap beetles. [5], Insecticides are not often applied in direct response to C. lugubris, but they are still effective when targeting other species. [1] This image, taken from Marini 2013, can provide a better look at the adult morphology and colouration. All rights reserved. Common baits include stale beer, molasses-water-yeast mixture, vinegar or any overripe fruit. [1] Reports have even indicated its spread to southern European countries, such as, Italy. Carbaryl and bifenthrin can be used to control severe infestations. 2020 [2] Larva present in corn kernels often go undiscovered and this can lead to their rejection and subsequent discarding. In this country, it is particularly common along the Atlantic coast. [1] When ready to pupate, the larva fall to the ground and bury themselves. The antennae of sap beetles have a club (knob) at the end. The most common species in Minnesota are the strawberry sap beetle (Stelidota geminata), picnic beetle (Glischrochilus quadrisignatus) and the dusky sap beetle (Carpophilus lugubris). All sap beetles have this feature and is a useful tool when identifying sap beetles. [2] Only very cold climatic regions are free of the genus Carpophilus. Outdoor biting insects and insect relatives. [2] The use of the dusky sap beetle to fight fungal infections is a possibility as well. Dusky Sap Beetle Mediated Dispersal of Bacillus subtilis to Inhibit Aspergillus flavus and Aflatoxin Production in Maize Zea mays L. PATRICK F. DOWD, FERNANDO E. VEGA, TERRY C. NELSEN & JOHN L. RICHARD Pages 221-235 Published online: 28 Jun 2010 When people talk about beetle pests in corn, they’re usually referring to damage that occurs below the soil level.
