||Potential biocontrol agent of skunkvine
||Graduate student Leo Camelo sets up a killing station for alfalfa looper moths in a potato field plot.
||Colorado potato beetle
||red flour beetle
||Red flour beetle, about one-eighth-inch long.
||Diaprepes root weevil
||Young (left) and older larvae of the Diaprepes root weevil on cakes of an artificial diet developed by ARS.
||Mediterranean fruit fly, Medfly
||Entomologists Michael Schauff (left) and Thomas Henry discuss the importance of leaf-footed bugs. Primarily seed and fruit feeders, these insects are potential pests of many crops.
||A large specimen of the leaf-footed bug, Thasus neocalifornicus, from the southwestern United States.
||Entomologist David Nickle examines an unidentified thrips species found in a shipment of cut flowers from South Africa and compares it to the image on the screen of a known thrips species. His rapid identification helps to ensure safe and timely shipments at various ports of entry.
||Sterile male screwworm fly marked with a numbered tag to study fly dispersal, behavior, and longevity.
||Culex nigripalpus larvae
||Several female papaya mealybugs (1/16 to 1/8 inch long) and two web masses on a stem of a red potato sprout.
||melaleuca leaf weevil
||The lower branch is normal, undamaged melaleuca. The top branch was defoliated by the melaleuca leaf weevil, Oxyops vitiosa.
||A normal, 12-day-old cotton bollworm larva raised on a control diet.
||In studies to track the development of Bt resistance, this undersized, 12-day-old larva was fed a diet containing Bt proteins.
||Pink bollworms emerging from a damaged cotton boll.
||coffee berry borer
||Adult female on a green coffee bean. Adult females bore a hole in coffee berries and lay their eggs near the two coffee beans found inside the berry. Once the eggs hatch, the larvae feed on the beans, rendering them unsuitable for commerce or greatly lowering their quality.
||black vine weevil
||Full-grown larva; actual size about 6 mm or 1/4 inch.
||black vine weevil
||Actual size about 7 mm or 3/8 inch.
||Close-up of a Cyrtobagous salviniae weevil larva. These 1/10th-inch long insects feed voraciously on buds and rhizomes of giant salvinia.
||The tortoise beetle is being considered for release as a biocontrol agent for tropical soda apple.
