Potato leafhopper is native to North America and commonly found throughout the U.S. Older potato leafhopper nymph with developing wing pads. Nymphs are easily disturbed and will attempt to walk away sideways or backwards when approached.įigure 2. Nymphs also start to develop wing pads after the third instar (Fig. First instars are pale but gradually gain more green color as they mature. Immature potato leafhoppers develop through five instars before becoming adults. Potato leafhopper eggs are cylindrical and translucent to pale green. Potato leafhopper adult with six white spots behind the white eyes. Adults are easily disturbed and will attempt to jump or fly away when approached.įigure 1. Also, there are prominent spines on the hind legs. The wings are clear and extend past the end of the abdomen. The head has short antennae, big, white eyes, and six white spots behind the eyes. The body is wedge-like with a broad head and a tapered abdomen (Fig. This leafhopper adult is bright, limey green and about 1/8 inches long (3 mm). The potato leafhopper, Empoasca fabae, is a member of the leafhopper family Cicadellidae and order Hemiptera. Change the lure at 15-20 days intervals.Adult. Monitor through phermone traps 10 to 12/ha for timely control measures.Set up bird perches (40 to 50/ha) of Insectivorous Birds at vegetative phase of crop.Set up light traps to attract and kill the moths.Release of mirid bug Cytorhinus lividipennis 50 – 75 egg/ m 2.Trichomma cnaphalocrocis - Ichnuemonidae Wasp.Itoplectis narangae - Ichnuemonidae Wasp.A fungal pathogen infects both the nymphs and adults of the green leafhopper. They are also attacked by aquatic veliid bugs, nabid bugs, empid flies, damselflies, dragonflies, and spiders.Strepsipterans, small wasps, pipunculid flies, and nematodes parasitize both the nymphs and adults.The most abundant predator is the green mired bug Cyrtorhinus lividipennis which predate on both eggs and nymphs.Oligosita yasumatsui (Hymenoptera: Trichogrammatidae).Maintain 2.5 cm of water in the nursery and broadcast anyone of the following in 20 cents Carbofuran 3 G 3.5 kg (or) Phorate 10 G 1.0 kg (or) Quinalphos 5 G 2.0 kg.Spray insecticides twice, 15 and 30 days after transplanting.įenitrothion 50 EC 80 ml (or) Phosphamidon 40 SL 50 ml (or) Fenthion 100 EC 40 ml (or) Quinalphos 25 EC 80 ml (or) Phosalone 35 EC 120 ml (or)Monocrotophos 36 SL 40 ml.Check 20 hills while walking diagonally across a transplanted field. Scout the field for the presence of Tungro and Green leaf hopper.ETL : 60/25 net sweeps (or) 5/hill at vegetative stage (or) 10/hill at flowering (or) 2/hill in tungro endemic area.Upland rice intercropped with soybean reduces the incidence of leafhoppers on rice compared to rice alone.Crop rotation with a non-rice crop during the dry season decreases alternate hosts for diseases.Good weed control in the field and on the bunds removes the preferred grassy hosts of Green leaf hopper and promotes crop vigor.Nitrogen should be applied as needed to avoid contributing to population or hindering plant recovery from plant hopper damage by applying insufficient nitrogen. ![]() Transplanting older seedlings (>3 weeks) reduces viral disease susceptibility transmitted by leafhoppers. ![]()
