L’inventaire odonatologique de trois oueds majeurs algériens : Kebir- Est, Seybouse et Rhumel, a permis l’identification de 40 espèces. Nos résultats révèlent la présence de Calopteryx exul, endémique maghrébin, dans l’oued Seybouse et semblent confirmer l’extinction de la population type dans l’oued Rhumel où l’espèce avait été découverte au XIXe siècle. Nos résultats indiquent également l’expansion de plusieurs espèces: Coenagrion caerulescens, Orthetrum nitidinerve, Trithemis kirbyi et Urothemis edwardsii dont la population relictuelle est en danger critique d’extinction. La mesure de diverses variables physicochimiques (altitude, température, conductivité, etc.) nous a permis d’explorer une possible co-structure entre les jeux de données faunistiques et de variables environnementales. L’analyse des données indique que la richesse spécifique est, selon l’oued, variablement correlée à l’hydropériode, à la conductivité et à la température de l’eau, suggérant son utilité dans l’évaluation de l’intégrité écologique des cours d’eau méditerranéens. -

Such ‘accompanying’ behaviour, which is shown by solitary individuals and varies with groups, males and females, and immature and mature adults, respect to wind direction and substrate in ways that indicate that the vertebrate is usually the perceived as a token stimulus attracting dragonflies to places where small flying rendered of insects are accessible as prey. Certain and probable examples accom- panying behaviour in other Anisoptera are discussed. INTRODUCTION Adults of the pan-African sympetrine libellulid Brachythemis leucosticta insect with of animals appear to associate prey the presence large that thereby serve as ‘token stimuli’(CORBET, 1962). Both sexes are attracted towards, and fly close to, large vertebrates such as cattle, hippopotamuses and humans as they the often abundant. move slowly through open grassland where dragonflies are Such ‘following’ behaviour presumably enables the dragonflies to feed on the small insects that are made to fly up by the vertebrates’ movement. Noting ‘following’ behaviour near Lake Victoria at Entebbe, Uganda (0° S'N., 32° 29'E), inferred that the CORBET (1962, p. 154) initially dragonflies were responding and the view directly to a large moving object not to prey dislodged by it, a expressed also by WORTH (1962) from observations made in Natal, South Africa. -

Holistic Survey on Damselfly (Anisoptera : Odonata)Diversity in Rice Ecosystem of Eastern India
International Research Journal of Natural Sciences Vol.4, No.4, pp.19-34, December 2016 ___Published by European Centre for Research Training and Development UK (www.eajournals.org) HOLISTIC SURVEY ON DAMSELFLY (ANISOPTERA : ODONATA)DIVERSITY IN RICE ECOSYSTEM OF EASTERN INDIA C.R. Satpathi and A. Mondal Department of Agricultural Entomology Bidhan Chandra Krishi Viswavidyalaya( State agricultural University), P.O- Mohanpur, Dist. – Nadia, West Bengal -741252, India ABSTRACT: This study highlights the richness of Damselfly (Anisoptera: Odonata) fauna associated with rice ecosystems in Eastern India.. Sampling of the Damselfly community was conducted during 2010-14 to determine species composition, abundance and distribution in 3 different habitats of rice fields which were selected at 60 m (Chakdaha), 600 m (Cooch Behar) and 1250 m (Kalimpong) respectively. Each location was surveyed at a biweekly interval after transplanting of rice plants and about 10 species of Damselfly were recorded as insect predators in rice crops of Eastern India. General morphology, biology, ecology, behavior of the Damselfly are being highlighted in the present investigation. After comparing different body parts, double branching keys are prepared for their easy identification. The studies of their diversity showed that maximum and minimum value of both Simpson and Shannon-Weiner index were at the flowering and the vegetative stage of crop respectively. The value of Margalef index and Menhinck index also indicated that the highest value in reproductive stage of rice crop. The studies on Evenness index designated that the value of E1, E2 and E3 were influenced by species richness and not evenness. Consequently the influence of fertilizer on the incidence of Damselfly in rice ecosystem showed that there was a remarkable increase of population where high doses of nitrogen (120 kg/ha) were applied followed by the use of mix fertilizer(120:60:60 N:P:K). -

A. pinheyi Balinsky, 1963 is considered by DAVIES & TOBIN (1984) to be synonym ofA. exilis Sélys, 1872.

Lahiri Zoological Survey of India, New Alipur, Calcutta - 700 053, India A list of odonate species that have not been reported from India since their description before 1948 is presented. Most of the 78 species or Hills, subspecies listed were described from North Bengal or Sikkim, Khasi and Western Ghats and Nilgiris. Conservation measures on the type locali- ties of the rare dragonflies in these areas are urged. INTRODUCTION The odonate fauna of India has been explored time and again by individual the Fraser collectors, specialists on group and various survey parties. (1933-36) summarized the earlier works. Since then a numberof survey reports have followed, adding new taxa or extending the knowledge of the range of the known ones. A careful consultation of literature reveals that a good majority ofthe known species are rare and seldom reported. Very little attempt has, however, been made so far to demarcate the rare Indian odonate species and envisage effective planning for their conservation, except for the relict dragonfly Epiophlebia laidlawiTillyard, which has been declared a protected species by the Wildlife Board, Government of India. LIST OF SPECIES NOT REPORTED FROM INDIA SINCE 1948 In order to promote general awareness about the recurrence of rareness in Indian odonate species, a list of 78 species that demand special consideration from the conservation point is presented here. It refers to all taxa that have not been reported for 40 since first described in India a variableperiod exceeding years, ever they were from the but prior 1948. -
