They were<em>; Aphis craccivora</em>, Order: Hemiptera: Aphididae,<em> Ophiomyia phaseoli</em>, Order: Diptera: Agromyzidae, <em>Thrips tabaci</em>, Order: Thysanoptera: Thripidae,<em> Bemisia tabaci,</em> Order: Diptera: Aleyrodidae,<em> Melanogromyza phaseoli </em>Order: Diptera: Agromyzidae as insect pests and <em>Spodoptera litoralis, </em>Order:Lepidoptera: Noctuidae<em>, </em>as insect visitors. However, <em>Coccinella undecimpunctata</em> Order: Coleoptera: Coccinellidae and <em>Chrysoperla carnea</em> Order: Neuroptera: Chrysopidae as a predator. The effect of daily max., Temp., daily min. Temp., and rang R.H%, plant age and other ecological parameters on population fluctuation of <em>A. craccivora</em> and <em>O. phaseoli</em> were tested. These two pests <em>A.craccivora</em> and <em>O. phaseoli</em> had three peaks during 1<sup>st</sup> and 2<sup>nd</sup> seasons. The mean numbers of tested insect pests were higher during second season than the first season. The first appearance of <em>A. craccivora</em> and <em>O. phaseoli</em> was at the 4<sup>th</sup> week of December, late January and 1<sup>st</sup> March in two successive years, these insects are dangerous insect pests in common bean plants fields. The combination effect of climatic factors, plant age and natural enemies on <em>A. craccivora</em> and <em>O.phaseoli </em>population fluctuation was presented as explained variance which was 81 and 89% of<em> A. craccivora</em> and 83 and 73% of <em>O. phaseoli</em> in the first and second seasons, respectively.</p> 2024-01-12T00:00:00+00:00 Copyright (c) 2024 https://dzarc.com/entomology/article/view/436 A preliminary survey of arthropods in organic and inorganic paddy fields in Cheranmahadevi Taluk, Tamil Nadu, India 2024-02-18T06:52:01+00:00 Sivanesh H mail@Mail.com Augustus Robince mail@mail.com Azhagu Raj R drazhaguraj@gmail.com <p>India has a primarily agrarian economy. Agriculture contributes around 16-17% to the overall Gross Domestic Product (GDP) of the country. In this study, conducted in rice fields at Pappakudi (8°45'44"N, and 77°30'59"E) and Odaikarai-Thulukapatti (8°46'52"N, and 77°31'01"E) Cheranmahadevi Taluk<strong>,</strong> Tirunelveli District in Tamil Nadu, India, arthropods were collected from the study area and classified. This collection was done using the roving survey method, and relative abundance percentage composition was analysed. The order Hymenoptera emerged as the most diverse group of beneficial insects in both organic and inorganic fields, notably ants and honey bees. Order Orthoptera, including grasshoppers, had the highest count of 27.7%. The Chrysomelid beetle was completely absent in the organic fields. The ant family Formicidae and the butterfly family Lycaenidae were not found in the inorganic fields. Both agricultural practices exhibited low counts of families and genera in the orders Lepidoptera (butterflies and moths) and Araneae (spiders). This study shows diverse arthropods damaging or benefiting paddy on organic and inorganic farms. Compositional analysis revealed differences in the presence and abundance of certain insect families among these two farming practices.</p> 2024-01-15T00:00:00+00:00 Copyright (c) 2024 https://dzarc.com/entomology/article/view/431 Exploration of attractants with different trap designs and lure mixtures for effective capturing of Bactrocera spp (Diptera: Tephritidae) in mango orchards of Saharanpur district of Uttar Pradesh, India 2024-02-08T08:58:03+00:00 Dil Mahjoora Majeed maahimajeed123@gmail.com Aijaz Majeed aijazmajeed8@gmail.com Shafkat Jabbar Mir shafkatjabbr12@gmail.com Sajjad Ahmad Khan sajjadahmdkheen@gmail.com Mohd Majid Jamali majidjamali1988@gmail.com <p>The study aimed to investigate the efficacy of various attractants, trap designs, and lure mixtures for capturing <em>Bactrocera </em>spp in mango orchards of Saharanpur district, Uttar Pradesh, India. <em>Bactrocera </em>spp, commonly known as fruit flies, pose a significant threat to mango cultivation by causing extensive damage to fruit quality and yield. This research, conducted in different mango orchards of various places viz; Behat, Nakur and Sadholi Qadeem of Saharanpur district, examined the impact of different lure mixtures in baited traps on the attraction of fruit flies, particularly <em>Bactrocera zonata</em> and <em>Bactrocera dorsalis, </em>to develop efficient and sustainable strategies for fruit fly management in these regions<em>. </em>The research into the fusion of various traps and lures to attract fruit flies of genus <em>Bactrocera</em> has revealed an intriguing interplay of attractants. The findings demonstrated that lure mixtures in baited traps influence the attraction of fruit flies in a species-specific manner, with different species exhibiting varying levels of attraction to different lure mixtures. Notably, the most attractive lure mixture varied among the species, underscoring the need for species-specific considerations in integrated pest management programs. A total of 3780 and 2129 flies were captured for a research period of 17 weeks during the year 2023 for <em>B. dorsalis</em> and <em>B. zonata</em> respectively. It was observed that most of the fruit flies were attracted towards the cylindrical traps possessed with methyl eugenol lure followed by a mixture of methyl eugenol and cue lure. These results shed light on the potential for optimizing bait mixtures based on the relative abundance and economic impact of different fruit fly species, offering valuable insights for local fruit fly pest control programs. Furthermore, the study highlights the importance of future research aimed at refining lure mixtures to match specific kairomone emissions and maximize attractiveness across all targeted species.</p> 2024-01-19T00:00:00+00:00 Copyright (c) 2024 Dil Mahjoora Majeed, Dr Aijaz Majeed, Shafkat Jabbar MIr, Sajjad Ahmad Khan, Dr Mohd Majid Jamali https://dzarc.com/entomology/article/view/437 First distributional record of ant species (Hymenoptera: Formicidae) from Botanical Garden, Puducherry, India 2024-02-26T11:00:50+00:00 Gowri K gowrikumar25@gmail.com Sankaraiyah K sankaraiyah@gmail.com <p>The current study examines the ant distribution at the Botanical Garden in the Union Territory of Puducherry, India, as there are still no prior ant diversity reports from this site. Ant community is an essential unit of any ecosystem because they serve as ecosystem engineers. But the field of myrmecology has received very little attention in India. During the investigation, 12 ant species from four subfamilies were identified, including Myrmicinae, Ponerinae, Formicinae, and Pseudomyrmicinae. This work is the first report on the distribution of ant species from this location.</p> 2024-01-22T00:00:00+00:00 Copyright (c) 2024 Gowri K, Sankaraiyah K https://dzarc.com/entomology/article/view/438 Host deprivation effects on the reproduction and survival of the parasitoid Campoletis chlorideae Uchida (Hymenoptera: Ichneumonidae) 2024-02-28T16:11:05+00:00 Amarendra Kumar Pandey jrf_amarendra@rediffmail.com <p>The ichneumonid <em>Campoletis chlorideae</em> Uchida is an arrhenotokous idiobiont parasitoid that infests second instar larvae of the pod borer, <em>Helicoverpa</em> <em>armigera</em> (Hübner), a severe pest of pulse crops in India. For successful biocontrol practices, abundant hosts must be present in fields at the time of the mass release of parasitoids. Host deprivation, in general, influences the reproduction and survival of parasitoids. However, how host deprivation affects the reproduction and survival of <em>C. chlorideae</em> is still unknown. In the present study, we attempted to evaluate the longevity, fecundity and progeny sex ratio of <em>C. chlorideae</em> in response to host deprivation. The second instar larvae of the H. armigera were reared on an artificial diet under laboratory conditions [22±4°C, 70±10% RH and 10:14 h (L:D) photo-period] and exposed as host to newly emerged mated female <em>C. chlorideae</em> deprived of hosts for 0, 1, 2, 3, 4 and 5 days and entire life (for longevity only).</p> 2024-01-23T00:00:00+00:00 Copyright (c) 2024 Amarendra Kumar Pandey https://dzarc.com/entomology/article/view/441 A preliminary study of moth species of verna 2024-03-08T07:45:37+00:00 Dafilgo Fernandes dafilgofernandes@gmail.com <p>Insect studies based on their diversity and ecological distribution in Goa are rare and can help us understand the differences in biodiversity within the region. Goa is a tropical region that is part of the Western Ghats hotspot, but there is paucity of literature on insects especially moth species, in this region. A moth survey was conducted during the monsoon season to observe moth species over a period of several months in Verna village in the southern part of Goa. The current exploration is the first report of moth observations on the Sal River in the Verna residential area. A total of 193 moth species were identified. Based on the number of species, the family Erebidae was the most dominant with 61 species, followed by Crambidae with 42 species, Noctuidae with 26 species, Geometridae with 19 species and Sphingidae with 5 species. The least dominant were Nolidae, Zygaenidae and Pterophoridae with 4 species each. Moth diversity and abundance in Verna is highest during the monsoon and is directly dependent on rainfall, probably because it stimulates the growth of various plant species on which moth larvae feed. This moth species in this discovery contributes significantly to the moth ecology in Verna, expanding the list of known moth species and furthering our understanding of their ecological role in the ecosystems of Goa.</p> 2024-01-29T00:00:00+00:00 Copyright (c) 2024 Dafilgo Fernandes
