It feeds on sorghum in Asia. We evaluated the capacity of non-cotton plant species (both naturally growing and cultivated) to function as alternative hosts for the cotton leaf hopper Amrasca devastans (Homoptera: Ciccadellidae) and its natural enemies. The Indian accession RG 43 is multiple resistant to leafhopper, wilt and nematode. They can infest 10–50% of the eggs during the first generation, and up to 90–100% on the second late-summer population. (Nielson, 1968), Thomas and Krishnaswami (784) first reported in 1939 this species as a vector of little leaf of brinjal (eggplant). These symptoms are manifested in the forms of etiolated spots and patches on leaves, browning, rotting of margins and tips, and drying of leaves. Most likely Amrasca biguttula biguttula; previously, Amrasca devastans, and Empoasca devastans. ), A. devastans (Dist. INTRODUCTORY 0000002042 00000 n, Studies on the cotton Jassid (Empoasca devastans Distant) in the Punjab. This species is found in Australia, China, India, the Malayan Archipelago, Myanmar, New Caledonia, Pakistan, Sri Lanka, and the Palearctic region (Ghosh, 2008). Capsule borer, Conogathes (Dichocrocis) punctifaralis Guen. 911 – 926. Red cotton bug, Dysdercus koenigii Fabricius, 1775. Peculiarly, they move diagonally across leaves. In recent decades, several scientific names (including Amrasca biguttula (Shir. (Pyralidae: Lepidoptera), is another serious pest of castor (R. communis L.). Ripersia sacchari Green, 1931; Ripersia rehi Lindinger, 1943; Tychea rehi Lindinger, 1943; Heterococcus rehi (Lindinger, 1943) Williams,1970; Heterococcus tuttlei Miller and McKenzie, 1970. are the ancestral plant hosts. Narrow. Sci., 10, pp. The head bug, C. angustatus Lethiery, is a key limiting factor in sorghum production (Young and Teetes, 1977; Sharma and Lopez, 1990). Required fields are marked *. Both nymphs and adults suck cell sap, usually from the ventral surfaces of leaves. This bug feeds on millets of the New World. An oil-based emulsion of B. bassiana conidia and its feasibility to be incorporated into imidacloprid control were examined against E. vitis population in tea fields in southern in China (Feng et al., 2004). In Europe, Empoasca leafhoppers tend to be particularly damaging, especially E. vitis. Leafhoppers (Hemiptera: Cicadellidae) are strong fliers and are much more mobile than aphids. The Kitchen Home Cooked For The Holidays Recipes, Uk State Pension Taxable In Australia Ato, Song Of Songs Commentary Charles Spurgeon, Potenzstörungen können ein Sympton für Arteriosklerose sein. Plant Protection and Quarantine Programs; United States. 1974, Saxena et al. This species is common in many areas of India (Afzal and Ghani 1953 [6]). No-bloom and single-bloom types are reported to be less resistant to leafhopper than double and triple-bloom types in castor (Jayaraj, 1968; Srinivas Rao et al., 2000; Vijaya Lakshmi et al., 2005). Um was handelt es sich ? The cotton jassid Empoasca devastans Distant has been reported as a major pest from all the cotton growing areas of the Indian Union. Apart from India, the bug has been reported from Kenya and Rwanda (Seshu Reddy and Omolo, 1985). Purple top in potato, which is caused by aster yellows mycoplasma- like organisms, is also transmitted by leafhoppers (Misra 1995). Taxonomic revisions on this genus clarified the identity of many species (Ghauri, 1971). Commonly called potato leafhopper, this species is more common outside India. Crown yellow with two black spots on anterior margin; pronotum orange yellow; elytra light yellow with two black spots distad of middle. 0000006212 00000 n The leafhopper vectors of phytopathogenic viruses (Homoptera, Cicadellidae). Studies on the parasites and predators of Empoasca devastans Distant (Homoptera: Jassidae). 1382 386 pp. Crops Affected by Empoasca devastans Distant; Rice: Citrus: Carrot: Barley: Apple: Tomato: Maize (Corn) Pear: Potato: Sugarcane: Elm: Strawberry: Wheat: Palms: Rubus: Sorghum: Grapevine: Papaya: Other (grasses/cereals) Ornamentals: Peach Leafhoppers appear unable to acquire witches’-broom phytoplasmas from potato since it is not their preferred host, and instead acquire the phytoplasmas from other infected host plants, including perennial legumes. Just like other microorganisms, the immune responses that fungi have to face upon invading the insect limit their application. Castor is a host to more than 100 species of insects and is used as an insect trap plant in several crops. Many agricultural pests can be harboured by alternative host plants but these can also harbour the pests’ natural enemies. STUDIES ON COTTON JASSID (EMPOASCA DEVASTANS DISTANT) IN THE PUNJAB* vii. Thanki et al. An oil-based emulsifiable formulation (2 × 107 conidia/mL) of B. bassiana containing 1% imidacloprid in 10% WP (wettable powder) produced 69% mortality in autumn weather conditions, though B. bassiana alone was not effective (Feng et al., 2004). Rice green leafhopper, Nephotettix cincticeps (Uhler, 1896). Juarez Murders By Year, It has a spot at the inner margins of the eyes; a pronotum with two large obscure ochraceous spots on the basal area; a scutellum with a small spot near the apex of the clavus, a transverse fascia to the corium, prosternum, abdominal segmental margins, and with stigmal spots; membrane is black, with a central white spot and two crescent white markings on the membranal suture; labium reaches or passes second coxae; legs are black, femora are distinctly spined beneath (Ghosh, 2008). 0000006887 00000 n is active throughout the year. Fairyfly (Hymenoptera, Mymaridae) egg parasitoids of the tea green leafhopper Empoasca (Matsumurasca) onukii Matsuda (Hemiptera, Cicadellidae), an economically important pest in Asia of the tea plant, Camelliasinensis, were identified from specimens reared in Japan.Using a combination of genetic and morphological evidence, Anagrus (Anagrus) rugmanjonesi Triapitsyn & Adachi-Hagimori, … If you do not receive an email within 10 minutes, your email address may not be registered, 0000239682 00000 n Pygofer in lateral aspect about as long as wide, ventral margin with distinct long spine extending posterodorsad beyond dorsal margin of pygofer; aedeagus in lateral aspect with long basal process; aedeagal shaft curved, short, attenuated apically; gonopore apical; style in dorsal aspect simple, lateral margin of apices serrate; female seventh sternum in ventral aspect with caudal margin convergent apically. Pronounced damage is usually caused only when infestations reach>10–15 leafhoppers/leaf. Stink bug, Dolycoris indicus StÃ¥l, 1876. Delphax oryzae Matsumura, 1906: 13; Nilaparvata greeni Distant, 1906: 486. In the absence of these hosts, it migrates to castor, alfalfa, and barseem (Butani and Jotwani 1984). Syn. How To Make Feta Cheese Without Culture, Several other species are important on potato in certain regions. However, at least three closely related species have been reported on potatoes in the United States, including E. filamenta in arid, high-altitude western intermountain regions, and E. abrupta and E. arida in arid, low-altitude Pacific Coast regions (DeLong 1931, Radcliffe 1982).

I Don't Have Time For Friends, Narrow. 2008). P. maidis-vectored maize mosaic virus (MMV) wiped out the maize crop of the Maya civilization in Central America and thus was considered to be one of the main reasons for the classic Maya collapse (Brewbaker, 1979; Hannikainen, 2011). Although closely related, these chinch bugs have been shown to elicit differential feeding responses in their grass hosts (Anderson et al., 2006). Chemical control of leafhoppers has shifted from synthetic pesticides, such as organophosphates, to ‘softer,’ nicotine-based compounds (e.g., imidacloprid). Original species combination: Derbe (Phenice) moesta Westwood, 1896. Original species combination: Eurycyrtus bellevoyei Reuter, 1879. Leafhopper, Empoasca devastans was reported to. It has been reported from Burma (Mathur 1953 [499]). Insecticides are not effective to control leafminer. Bureau of Entomology and Plant Quarantine; United States. TH~ cotton Jassid (Empoasca devastans Dist.) C. angustatus was first described by Lethierry in 1893 from the former state of Madras, India (Distant, 1902). It is a symbiotic bacterium that limits the multiplication of X. fastidiosa in the insect vector (Bextine et al., 2004). These are the common names given to Amrasca devastans, but the species in the Pacific has not been identified.. Scientific Name. These insects suck the sap from leaves and developing grains of sorghum, pearl millet, and barnyard millet. 2010). Empoasca devastans[Amrasca biguttula] Dist has been reported as a major pest from all the cotton-growing areas of India, It also attacks other crops and ornamental plants. 0000003480 00000 n Indian Journal of Entomology 27, 104-106. Learn about our remote access options, Indian Agricultural Research Institute, New Delhi, India. 0000002188 00000 n. Though, 8 species of jassids has been reported to feed on cotton, A. devastans is the most dominant & distributed in all the cotton growing areas of the country. In addition to toxins derived from entomopathogenic fungi can interfere with the cellular and humoral immunity of the host, some entomopathogenic fungi have evolved strategies to evade the recognition of immune system by changing the structure of their cell surfaces (Wang and St Leger, 2006). Beauveria bassiana is the most widely used fungus for controlling agricultural and forestry pests. Dysdercus cingulatus Fabricius, 1775: 719. The leafhopper vectors of phytopathogenic viruses (Homoptera, Cicadellidae). The average development time for nymphs is 15 days. Original species combination: Pyrops perpusilla Walker, 1851: 269. Over the years, nearly 40 types of agricultural and forestry pests have been effectively controlled by B. bassiana in China, including Dendrolimus kikuchii, Empoasca pirisuga, Pyrausta nubilalis and Carposina nipponensis (Xie et al., 2012). Mode of spread and survival The disease is transmitted by leaf hoppers, Hishimonas phycitis and Empoasca devastans and grafting. 2.16).
