Sap beetles are a common pest problem in strawberries, raspberries, tomatoes, sweet corn and other garden fruits and vegetables. Here we present a fast, efficient and adaptable way to discriminate morphologically highly similar larvae of two closely related species of sap-feeding beetles of the family Nitidulidae, that will aid in investigating the population dynamics between these two sympatric species, but also the interactions of beetles, fungi and trees . However, if we use insecticides then we kill not only the sap suckers but also non-target species such as lady beetles and their larvae, hover flies and their larvae, parasitic wasps and their larvae and the list goes on. The large irregular holes and decay spread from fruit to fruit and can cause a large amount of produce to be unusable. Dowd (2000) compared the incidence of sap beetle adults, larvae, and their damage on two varieties of corn, Bt corn and non-Bt hybrid corn. Larvae are white with a tan head, 3 pairs of legs and 2 horn-shaped structures on their back end. In some species the elytra (wing covers) cover the abdomen, while in others the tip of the abdomen is exposed. These scavenger beetles feed on developing, ripe or overripe produce as well as plant sap exuding from wounds and fungi. Japanese Beetle Both Japanese beetles and sap beetles feed on ripe fruit, chewing large holes into the … They have a brown, rear body section with two or four protruding points. Tree-Killing Beetles. They are very small (up to 12mm [almost ½ inch]) cream or light tan larvae with brown heads. Pick berries and fruit before they become over-ripe. The corn sap beetle and dried fruit beetle can be found in a wide variety of ripe and decomposing fruit in the field and is a serious pest of dried fruit. The ensuing larvae will feed inside the fruit and may not be noticed until the fruit starts decomposing as a result of the damage. The sap beetles, also known as Nitidulidae, are a family of beetles.. Predators are the only effective way to deal with most sap sucking insects. Beetles may bore into tree limbs and bark or into the root systems, causing extensive damage. There are several varieties of sap beetle, also known as dried fruit beetles. Sap beetle larvae are sometimes mistaken for small corn borers. Handle them carefully to prevent bruising. They are small (2–6 mm) ovoid, usually dull-coloured beetles, with knobbed antennae.Some have red or yellow spots or bands. Sap (or Picnic) Beetle Larva. Dowd's study showed that direct damage can be induced by dusky sap beetles. Both adult sap beetles and fruitworm larvae feed on ripe fruit, however, in the case of sap beetles, the holes may be larger and the presence of the bug more easily detected. Sap beetle, (family Nitidulidae), any of at least 2,000 species of beetles (insect order Coleoptera) usually found around souring or fermenting plant fluids (e.g., decaying fruit, moldy logs, fungi).Sap beetles are about 12 mm (0.5 inch) or less in length and oval or elongated in shape. Overripe fruit is very attractive to sap beetles, and often they can be found on previously damaged or diseased fruits. Control Since spoiling plant material is required to attract these beetles, good control of insects and diseases will largely prevent trouble. The dried fruit beetle can also be found on stored corn, cornmeal, wheat, oats, rice, beans, nuts, peanuts, cottonseed, copra, … The cavities chewed in fruit can also serve as egg laying sites for sap beetles. They feed mainly on decaying vegetable matter, over-ripe fruit, and sap.Sap beetles coexist with fungi species and live in habitats of coniferous trees.
