Diagnostic Notes **Identification is currently undergoing peer review as part of the National Diagnostic Protocols by SPHDS.** Symptoms of mango web weaver infestation include; a nest of leaves woven together by silk, completely defoliated leaves leaving mid rib, dried shrivelled shoots and an absence of flowering and fruiting (Singh 1988). Egg period between 4-7 days Larval period between 25-33 days; smooth and active; 5 instars; fully mature larva 25 mm long; 5 mm wide; pale grey with prominent white stripes on the dorsum. Pupal period between 8-45 days; pupate in silken cocoon and hibernate in the soil at depths of 8 – 10 cm **Adult** wing span 31mm; body length 14mm; males are smaller than females; forewings grey with patches of white scales; hindwings grey colour with less patches of white scales; nocturnal fliers (Singh 1988). Under laboratory conditions, the adult female can lay up to 155 eggs and survive between 3-5 days. The genitalia of _Orthaga euadrusalis _have not been described.

  • Ecological Studies on Mango Leaf Webber (Orthaga Exvinaceahamp.)
    Internat. J. agric. Sci. Vol.2 No.2 July 2006 : (308-311) 308 Ecological studies on mango leaf webber (Orthaga exvinacea Hamp.) in Andhra Pradesh as a basis for IPM M. Kannan*1 and N. Venugopala Rao Department of Entomology, S.V. Agricultural College, TIRUPATI (A.P.) INDIA ABSTRACT The influence of ecological factors viz., biotic (Host plant) and abiotic factors (weather parameters) on the abundance and population fluctuation of leaf webber, Orthaga exvinacea (Hamp.) on mango under the conditions of Chittoor district were worked out. Peak incidence was observed during first fortnight of November (19.4 webs/tree). However, gradual increase was observed from the first fortnight of July (2.6 webs/tree) and declined during second fortnight of January (3.2 webs/tree). Correlation studies between incidence and weather parameters showed positive relationship with minimum temperature, relative humidity and rainfall and negative relationship with maximum temperature. None of the varieties was free from infestation. The infestation ranged from 7.80 to 29.47 webs/tree, 5.82 to 22.55 leaves/web and 1.92 to 29.47 larvae/tree. Variety Neelum showed less infestation, while Bangalore showed severe infestation and other varieties viz., Neeleghan, Cherakurasam, Mulgova, Rumani, Baneshan and Swarnajahangir have moderate infestation. Result of the study also revealed that older mango trees (15 and above years old) were more susceptible (18.26, 348.75, 121.61 webs/tree, webbed leaves/tree and larva/ tree, respectively) to leaf webber damage than young trees (0-5 years old). Key Words: Mango leaf webber, Ecological studies, Varietal susceptibility, Abiotic factors INTRODUCTION Impact of abiotic factors on population dynamics of leaf webber Mango, Mangifera indica is an important fruit crop of India.

  • EFFECTS of BLOOD FEEDING on the TRANSCRIPTOME of the MALPIGHIAN TUBULES in the ASIAN TIGER MOSQUITO AEDES ALBOPICTUS Thesis
    EFFECTS OF BLOOD FEEDING ON THE TRANSCRIPTOME OF THE MALPIGHIAN TUBULES IN THE ASIAN TIGER MOSQUITO AEDES ALBOPICTUS Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master in Science in the Graduate School of The Ohio State University By Carlos J. Esquivel Palma, B.S. Graduate Program in Entomology The Ohio State University 2015 Master’s Examination Committee: Dr. Peter M. Piermarini, Advisor Dr. David L. Denlinger Dr. Andrew P. Michel Copyright by Carlos J. Esquivel Palma 2015 Abstract Mosquitoes are one of the major threats to human health worldwide. They are vectors of protozoans, arboviruses, and filarial nematodes that cause diseases in humans and animals. The Asian tiger mosquito Aedes albopictus is a vector of medically important arboviruses such as dengue fever, chikungunya fever, yellow fever, eastern equine encephalitis, La Crosse encephalitis, and West Nile fever. Control of these diseases often involves control of the mosquito vectors with chemical insecticides. However, the use of a limited number of chemicals with similar modes of actions has led to resistance in several mosquito species. The development of new insecticides with novel modes of action is considered a promising strategy to overcome resistance. The Piermarini lab has recently shown that the renal (Malpighian) tubules of mosquitoes are promising physiological targets to disrupt for killing mosquitoes via a novel mode of action. The Malpighian tubules play a critical role in the acute processing of blood meals, by mediating the rapid excretion of water and ions derived from the ingested blood. However, the physiological roles of Malpighian tubules during the chronic processing of blood meals after the initial diuresis is complete (~1-2 h after feeding) are not known.

  • Integrated Field Management of Henosepilachna Vigintioctopunctata (Fabr.) on Potato Using Botanical and Microbial Pesticides Sunil Kr
    151 Management of Henosepilachna vigintioctopunctata JBiopest, 5 (supplementary): 151-154 (2012) 151 Integrated field management of Henosepilachna vigintioctopunctata (Fabr.) on potato using botanical and microbial pesticides Sunil Kr. Ghosh and Gautam Chakraborty ABSTRACT Potato (Solanum tuberosum L.) is cultivated in India in a commercial scale and this crop is susceptible to various insect pests of which epilachna beetle (Henosepilachna vigintioctopunctata Fabr.) causes heavy damage. Studies were made to evaluate efficacy of extracts from plants such as Pongamia pinnata L. (Karanja) and Nicotiana tabacum L., botanical insecticide such as azadirachtin (1500 ppm), microbial insecticides like Beauveria bassiana Vuillemin against epilachna beetle infesting potato crop under field conditions of the sub-Himalayan region of north-east India during the rabi season. Methanol was used as solvent for extracting from fruits of Pongamia and water for leaves of Nicotiana tabacum. Cartap hydrochloride 50% SP was used as check. Three sprays at 10-day intervals were made, starting with the initiation of infestation. Total epilachna beetle numbers (both adult and grub) per plant were counted at 4 and 9 days after treatment (DAT). The data thus obtained were converted to the per cent reduction of the epilachna beetle population and analyzed statistically. Significant differences were found in the efficacy of different treatments in reducing the pest population and their persistence at different DAT. Cartap hydrochloride was found the most effective treatment for the controlling epilachna beetles, followed by botanical insecticide, azadirachtin. It was observed that botanical insecticide, azadirachtin and extracts of Pongamia at a concentration of 5 % gave satisfactory control, recording more than 50 % mortality.

    RESEARCH PAPER Zoology Volume : 4 | Issue : 1 | Jan 2014 | ISSN - 2249-555X Life Tables And Intrinsic Rate of Increase in Mango Leaf Webber Orthaga Euadrusalis Walker (Pyralidae : Lepidoptera) KEYWORDS Orthaga euadrusalis , mango pest, life tables, intrinsic rate T. V. Sathe Department of Zoology, Shivaji University, Kolhapur 416 004, India. ABSTRACT Orthaga euadrusalis Walker (Lepidoptera : Pyralidae) is leaf webber of mango Margifera indica. It is most ac- tive from August to December. However, it found on the crop throughout the year and completes many over- lapping generations. Duration of immature stages under laboratory conditions (24±1oC, 70-75% RH & 12 hr photoperiod) was 46 days. Its longevity and oviposition days averaged 4.21 and 3.60 days respectively. Intrinsic rate of increase was 0.09, maximum progeny production 'mx' (30.6) was on 2nd day, first mortality in female was observed on 4th day. Its population multiply 69.6 times in mean generation time 'T' of 47.14 days. INTRODUCTION The control of insect pests of economic importance is the most pressing problem of recent years and for this the essen- tial objects are to make the estimates of the rate of growth of the pests (Howe, 1953). The inherent characteristics of the animals are collectively called the “innate capacity for in- crease”. Thompson (1924) for the first time developed math- ematical model for population dynamics of insects. Later, Lotka (1925) investigated a function for “the intrinsic rate of natural increase, rm”. However, Birch (1948) applied this func- tion for the first time to insects. Mango leaf webber Orthaga euadrusalis Walker (Lepidop- tera : Pyralidae) is potential pest of mango Mangifera indica (Verma & Singh, 2010).
