Insect Pests of Mubgbean and Their Control N.S. Talekar Entomologist Insect Pests of Mubgbean and Their Control N.S. Talekar Entomologist Asian Vegetable Research and Development Center Shanhua, Tainan, Taiwan 1. Introduction Mungbean, Vigna radiata (L.) Wilczek, is a major legume crop grown widely in south- and southeast Asia, mostly on small-scale family-owned farms. This low input, short duration crop is prized for its seeds, which are high in protein, easily digested, and consumed as food. It is an important source of dietary protein, especially in Indian Subcontinent where consumption of animal protein is very low. Because of its short duration, mungbean is easily adopted to multiple cropping system in the drier and wanner climates of lowland tropics and subtropics. Despite its short duration, large number of insect pests attack mungbean from soon after germination to harvest limiting the yield and some pests destroy seeds in storage (Table 1). Since mungbean is grown mainly in the tropical climates, insect pests play important role in the economic production of the crop. The insect pests that attack mungbean can be classified based on their appearance in the field as it relates to the phenology of mungbean plant. They are thus: 1. stem feeders, 2. foliage feeders, 3. pod feeders, and 4. storage pests. This classification is convenient in judging the economic importance of the pest, especially their influence on seed yield, and in devising control measures. In this chapter, therefore, the pests will be discussed according to this chronological order. The major stem feeders, especially in seedling stage are the agromyzid flies, so call beanflies, consisting of at least three species. In India the girdle beetle, Oberia brevis (Swedenbord), a major pest of soybean, sometimes attack mungbean. Its damage, however, is minor and localized. Large number of foliage feeders belonging to orders Lepidoptera and Coleoptera feed on the foliage of mungbean and several other related legumes. These include armyworms (Spodoptera exigua (Huebner), Spodoptera litura (F.)) hornwonn; (Agris convolvuli (L.)), cotton leafhopper (Amrasca biguttula biguttula Nishida), Bihar hairy caterpillar (Spilosoma obliqua (Walker)), Epilachna spp. and flea beetles, grasshoppers etc. Most of these insects are highly polyphagous and feed on wide variety of legumes and non- legumes. Their damage to mungbean is highly localized and most case minor. However, two groups of insects, aphids especially black bean aphids, Aphis craccivora Koch, and thrips belonging to genus Megalurothrips are especially -10 1- damaging to mungbean and other related legumes They will be discussed here. Major pod feeders are the hemipteran bugs especially the'most widespread southern green stink bug, Nezara viridula L., and two species of lepidopterous podborer, the Maruca podborer, Maruca testulalis (Geyer) and Limabean podborer Etiella zinckenella Tretsche. Although other species such as the tomato fruitworm, Helicoverpa armigera (Huebner), Asiatic cornborer, Ostrinia furnacalis (Guenee) and others attack mungbean and other legumes, these legumes are secondary or minor hosts of these pests. Information on these pests can be more easily obtained from study on other crops. The storage pests include species of bruchids belonging to genus Callosobruchus are primary pests of mungbean, especially on stored seeds. Their control is especially important to reduce avoidable losses. - 102- Table 1.

AMETA Department of Entomology, Rajasthan College of Agriculture (MPUAT), Udaipur (Rajasthan) 313001 *[email protected] ABSTRACT A field experiment to record the seasonal incidence of sap sucking insect pests of cotton was carried out during May to November, 2012 at the Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan). The study revealed that the incidence of sap sucking insect pests started at 26th SMW and the peak population of aphids (52.80 aphids/plant) and thrips (41.60 thrips/plant) was recorded in 41st and 40th SMW, respectively; whereas, the population of jassids and whitefly reached the peak with mean 19.80 jassids /plant and 31.87 whiteflies/plant during the 31st and 30th SMW, respectively. The jassid and whitefly population was significantly and positively correlated to mean atmospheric temperature and mean relative humidity. Aphid population was positively correlated to mean atmospheric temperature and mean relative humidity. The mean relative humidity had significant positive correlation with the population of thrips. Key words: Seasonal incidence, sap sucking insect pests, cotton. INTRODUCTION MATERIALS AND METHODS Cotton (Gossypium spp.), an important commercial The seasonal incidence of insect pests of cotton was crop in Indian agriculture, is cultivated in varied agro- studied for which an experiment was laid out in uniformly climatic conditions across nine major states of India sized plots measuring 5m × 5m replicated six times.

We evaluated the species concept for a common generalist moth occurring in New Guinea and Australia, Homona mermerodes, in light of host plant records and mitochondrial cytochrome c oxidase I haplotype diversity. Genetic divergence among H. mermerodes moths feeding on different host tree species was much lower than among several Homona species. Genetic divergence between haplotypes from New Guinea and Australia was also less than interspecific divergence. Whereas molecular species identification methods may reveal cryptic species in some generalist herbivores, these same methods may confirm polyphagy when identical haplotypes are reared from multiple host plant families. A lectotype for the species is designated, and a summarized bibliography and illustrations including male genitalia are provided for the first time.

  • INSECT PESTS of GROUNDNUT (Arachis Hypogaea L.), NATURE of DAMAGE and SUCCESSION with the CROP STAGES
    ISSN 0258-7122 Bangladesh J. Agril. Res. 39(2): 273-282, June 2014 INSECT PESTS OF GROUNDNUT (Arachis hypogaea L.), NATURE OF DAMAGE AND SUCCESSION WITH THE CROP STAGES G. C. BISWAS1 Abstract Thirty six species of insect pests were found to infest the different growth stages of groundnut crop at Gazipur, Bangladesh during the rabi seasons of 2008-09 and 2009-010. Among the recorded pest species, the hairy caterpillar, Spilarctia obliqua ( Walker); common cutworm, Spodoptera litura F.; jassid, Empoasca terminalis Distant ; leaf miner, Stomopteryx nerteria M. and leaf roller, Anersia ephippias (Meyr.) were considered as the major pests, while the rests were of minor importance on the basis of their population densities/plant, nature and extent of damage and yield reductions. Most of the major and minor pests infested during the vegetative to pre-maturity stages (45-95 DAS) and the maximum infestation occurred during pod formation and pod filling stages (50- 80 DAS) of the crop in both the years. Keywords: Insect pests, groundnut, damage, succession, crop stages. Introduction Groundnut (Arachis hypogaea L.) is an important oilseed crop in Bangladesh on the basis of both in acreage and annual production (Biswas et al,. 2000; Mondal and Wahhab, 2001.) Its cultivation covered about 87,000 hectares and produced about 1,25,000 metric tons of seeds during 2011-12 (Krishi Diary, 2013). One of the major constraints to the successful groundnut production in Bangladesh is the damage caused by insect and mite pests. Studies reveal that 15 - 20 percent of the total oilseed production is lost directly or indirectly by the attack of insect and mite pests every year (Biswas and Das, 2011).

  • Relative Susceptibility of Crotalaria Spp. to Attack by Etiella Zinckenella in Puerto Rico1
    Relative susceptibility of Crotalaria spp. to attack by Etiella zinckenella in Puerto Rico1 Alejandro E. Seganu-Cannona and Pedro Barbosa2 ABSTRACT Four Crotalaria species were found attacked by the lima bean pod borer Etiella zinckenella (Treit.) in Puerto Rico: C. pallida, C. anagyroides, C. zanzibariea and C. incana. Non-susceptible species were C. retasa, C. stipularia and C. lanceolata. Early literature observations on the effect of soil characteristics (pH, soil penetrability, and organic matter) on attack rates of this borer to C pallida could not be confirmed on the basis of field observations. Only plant patch size seemed to be positively correlated with attack rates. Female oviposition patterns are discussed. Oviposition on C pallida field collected pods was restricted to green pods larger than 3.2 cm. No eggs were found on senescent pods. INTRODUCTION The lima bean pod borer, Etiella zinckenella (Treit.), was reported in Puerto Rico in 1890 (20). Since then, it has been studied by many visiting and resident entomologists. Leonard and Mills (6) first reported this pyralid boring on pods of lima beans, cowpeas, pigeon peas and Crotalaria (no species given). Wolcott (17,18) recorded that among all species of Crotalaria, only C. incana L. was attacked, and C. retusa L. appeared immune to this borer. This author also reported that Crotalaria plants growing on sandy soils were more susceptible to pod loss by E. zinckenella than those growing on clay soils. Further studies by Scott (12) corroborated Wolcott's observations on C. retusa resistance and added C stipularia Desv. to the list of resistant species.

  • Widespread Occurrence of Black-Orange-Black Color Pattern in Hymenoptera
    Journal of Insect Science, (2019) 19(2): 13; 1–12 doi: 10.1093/jisesa/iez021 Research Widespread Occurrence of Black-Orange-Black Color Pattern in Hymenoptera R. Mora1,2,3 and P. E. Hanson2 1Universidad de Costa Rica, Centro de Investigación en Biología Celular y Molecular, Ciudad de la Investigación Postal 11501-2060, San Pedro de Montes de Oca, SJ, Costa Rica, 2Universidad de Costa Rica, Escuela de Biología, Apartado Postal 11501-2060, San Pedro de Montes de Oca, SJ, Costa Rica, and 3Corresponding author, e-mail: [email protected] Subject Editor: Phyllis Weintraub Received 19 October 2018; Editorial decision 3 February 2019 Abstract Certain color patterns in insects show convergent evolution reflecting potentially important biological functions, for example, aposematism and mimicry. This phenomenon has been most frequently documented in Lepidoptera and Coleoptera, but has been less well investigated in Hymenoptera. It has long been recognized that many hymenopterans, especially scelionids (Platygastridae), show a recurring pattern of black head, orange/red mesosoma, and black metasoma (BOB coloration). However, the taxonomic distribution of this striking color pattern has never been documented across the entire order. The main objective of our research was to provide a preliminary tabulation of this color pattern in Hymenoptera, through examination of museum specimens and relevant literature. We included 11 variations of the typical BOB color pattern but did not include all possible variations. These color patterns were found in species belonging to 23 families of Hymenoptera, and was most frequently observed in scelionids, evaniids, and mutillids, but was relatively infrequent in Cynipoids, Diaprioids, Chalcidoids, and Apoids.
