Morphology and Adaptation of Immature Stages of Hemipteran Insects
© 2019 JETIR January 2019, Volume 6, Issue 1 www.jetir.org (ISSN-2349-5162) Morphology and Adaptation of Immature Stages of Hemipteran Insects Devina Seram and Yendrembam K Devi Assistant Professor, School of Agriculture, Lovely Professional University, Phagwara, Punjab Introduction Insect Adaptations An adaptation is an environmental change so an insect can better fit in and have a better chance of living. Insects are modified in many ways according to their environment. Insects can have adapted legs, mouthparts, body shapes, etc. which makes them easier to survive in the environment that they live in and these adaptations also help them get away from predators and other natural enemies. Here are some adaptations in the immature stages of important families of Hemiptera. Hemiptera are hemimetabolous exopterygotes with only egg and nymphal immature stages and are divided into two sub-orders, homoptera and heteroptera. The immature stages of homopteran families include Delphacidae, Fulgoridae, Cercopidae, Cicadidae, Membracidae, Cicadellidae, Psyllidae, Aleyrodidae, Aphididae, Phylloxeridae, Coccidae, Pseudococcidae, Diaspididae and heteropteran families Notonectidae, Corixidae, Belastomatidae, Nepidae, Hydrometridae, Gerridae, Veliidae, Cimicidae, Reduviidae, Pentatomidae, Lygaeidae, Coreidae, Tingitidae, Miridae will be discussed. Homopteran families 1. Delphacidae – Eg. plant hoppers They comprise the largest family of plant hoppers and are characterized by the presence of large, flattened spurs at the apex of their hind tibiae. Eggs are deposited inside plant tissues, elliptical in shape, colourless to whitish. Nymphs are similar in appearance to adults except for size, colour, under- developed wing pads and genitalia. 2. Fulgoridae – Eg. lantern bugs They can be recognized with their antennae inserted on the sides & beneath the eyes. -

FROM THE SOLITARY BEE TO THE SOCIAL BEE. THE INVENTIVENESS OF CHILDREN IN THE ACQUISITION OF BEEKEEPING SKILLS (SOUTHWESTERN MOROCCO) Romain SIMENEL, Yildiz AUMEERUDDY-THOMAS, Morgane SALZARD & Lahoucine AMZIL* Résumé – De l’abeille solitaire à l’abeille sociale. Inventivité des enfants et apprentissage de l’apiculture (sud-ouest du Maroc). À partir de plusieurs exemples ethnographiques du sud- ouest marocain, le propos de cet article est de restituer la part de l’enfant dans son apprentissage de l’apiculture, notamment lors de l’étape de l’essaimage et dans la relation aux abeilles solitaires. Ceci permet de mieux comprendre comment la vocation d’apiculteur émerge d’une transmission culturelle qui s’appuie en grande partie sur l’expérience autonome et ingénieuse des enfants avec la biodiversité qui les entoure. Pour suivre le processus de transmission et d’apprentissage des savoirs apicoles, cet article propose d’analyser le contexte culturel de sensibilisation de l’enfant à l’abeille dès le plus jeune âge et d’identifier les lieux de l’apprentissage en fonction des différentes expériences avec l’abeille et des tâches apicoles. Enfin et surtout, nous chercherons à confronter cette sensibilisation par le monde des adultes aux apprentissages, liés à la pratique de jeux éducatifs propres à l’univers des enfants avec des abeilles solitaires, préparant à la compréhension du monde des abeilles et des techniques apicoles. Mots clés – Apprentissage ; apiculture ; enfants ; imagination ; biodiversité ; savoirs Abstract – Based on several ethnographic examples from southwestern Morocco, this paper aims at restoring the role of children as significant contributors in the acquisition and learning of their bee-keeping skills, particularly during the swarming season and during their relationship with solitary bees. -

Digging Deeper Into the Ecology of Subterranean Ants: Diversity and Niche Partitioning Across Two Continents
diversity Article Digging Deeper into the Ecology of Subterranean Ants: Diversity and Niche Partitioning across Two Continents Mickal Houadria * and Florian Menzel Institute of Organismic and Molecular Evolution, Johannes-Gutenberg-University Mainz, Hanns-Dieter-Hüsch-Weg 15, 55128 Mainz, Germany; [email protected] * Correspondence: [email protected] Abstract: Soil fauna is generally understudied compared to above-ground arthropods, and ants are no exception. Here, we compared a primary and a secondary forest each on two continents using four different sampling methods. Winkler sampling, pitfalls, and four types of above- and below-ground baits (dead, crushed insects; melezitose; living termites; living mealworms/grasshoppers) were applied on four plots (4 × 4 grid points) on each site. Although less diverse than Winkler samples and pitfalls, subterranean baits provided a remarkable ant community. Our baiting system provided a large dataset to systematically quantify strata and dietary specialisation in tropical rainforest ants. Compared to above-ground baits, 10–28% of the species at subterranean baits were overall more common (or unique to) below ground, indicating a fauna that was truly specialised to this stratum. Species turnover was particularly high in the primary forests, both concerning above-ground and subterranean baits and between grid points within a site. This suggests that secondary forests are more impoverished, especially concerning their subterranean fauna. Although subterranean ants rarely displayed specific preferences for a bait type, they were in general more specialised than above-ground ants; this was true for entire communities, but also for the same species if they foraged in both strata.

POPULATION ECOLOGY AND INTEGRATED MANAGEMENT OF SOFT WAX SCALE (CEROPLASTES DESTRUCTOR) AND CHINESE WAX SCALE (C. SINENSIS) (HEMIPTERA: COCCIDAE) ON CITRUS A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University Peter L. La Lincoln University 1994 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Ph.D. POPUlATION ECOWGY AND INTEGRATED MANAGEMENT OF SOFT WAX SCALE (CEROPLASTES DESTRUCTOR) AND CHINESE WAX SCALE (c. SINENSIS) (HEMIPTERA: COCCIDAE) ON CITRUS Peter L. La Soft wax scale (SWS) Ceroplastes destructor (Newstead) and Chinese wax scale (CWS) C. sinensis Del Guercio (Hemiptera: Coccidae) are indirect pests of citrus (Citrus spp.) in New Zealand. Honeydew they produce supports sooty mould fungi that disfigure fruit and reduce photosynthesis and fruit yield. Presently, control relies on calendar applications of insecticides. The main aim of this study was to provide the ecological basis for the integrated management of SWS and CWS. Specific objectives were to compare their population ecologies, determine major mortality factors and levels of natural control, quantify the impact of ladybirds on scale populations, and evaluate pesticides for compatibility with ladybirds. Among 57 surveyed orchards, SWS was more abundant than CWS in Kerikeri but was not found around Whangarei. Applications of organophosphates had not reduced the proportion of orchards with medium or high densities of SWS. Monthly destructive sampling of scale populations between November 1990 and February 1994 was supplemented by in situ counts of scale cohorts. Both species were univoltine, but SWS eggs hatched two months earlier than those of CWS, and development between successive instars remained two to three months ahead.
