SHAH† CABI Bioscience UK Centre, Silwood Park, Ascot, Berks. SL5 7TA, UK. E-mail: h.evans!cabi.org Received 2 September 2001; accepted 28 April 2002. The occurrence of disease outbreaks associated with the genus Sorosporella on grasshoppers and locusts (Orthoptera: Acridoidea) in Africa is reported. Infected hosts, representing ten genera within five acridoid subfamilies, are characterized by red, thick-walled chlamydospores which completely fill the cadaver. On selective media, the chlamydospores, up to seven-years-old, germinated to produce a Syngliocladium anamorph which is considered to be undescribed. The new species Syngliocladium acridiorum is described and two varieties are delimited: var. acridiorum, on various grasshopper and locust genera from the Sahelian region of West Africa; and, var. madagascariensis, on the Madagascan migratory locust. The ecology of these insect-fungal associations is discussed. Sorosporella is treated as a synonym of Syngliocladium. INTRODUCTION synanamorph, Syngliocladium Petch.

Load Capacity of Workers of Atta Robusta During Foraging (Hymenoptera: Formicidae) by Fabiola Bonicenha Endringer1, Ana Maria Viana-Bailez1, Omar E
839 Load Capacity of Workers of Atta robusta During Foraging (Hymenoptera: Formicidae) by Fabiola Bonicenha Endringer1, Ana Maria Viana-Bailez1, Omar E. Bailez1, Marcos da Cunha Teixeira2, Victor Luiz de Souza Lima1 & José Hildefonso de Souza1 ABSTRACT Worker ants are highly polymorphic in the genus Atta and they are usu- ally classified into castes according to the specific functions they perform in a colony. Minor workers (head width ≤ 2.0 mm) help to maintain and grow the symbiotic fungus whereas larger workers (head width > 2.0 mm) cut and transport plant fragments. This study investigated the roles in the cutting and transporting of different plant resources of differentAtta robusta worker classes that were classified based on the size of their head capsule. Experiments were conducted in the restinga of Grussaí/Iquipari, São João da Barra, Rio de Janeiro State, Brazil. In each month between October 2009 and September 2010, we collected 100 ants and their respective loads from the trails of four nests of Atta robusta. The samples were individually transported to the labo- ratory, where the ants and their loads were weighed and the head capsules of the ants were measured. Large ants transported heavier loads. These ants usually transported more fruit and seeds than smaller ants.

Management of Insect Pests by Microorganisms
Proc Indian Natn Sci Acad 80 No. 2 June 2014 Spl. Sec. pp. 455-471 Printed in India. Review Article Management of Insect Pests by Microorganisms B RAMANUJAM*, R RANGESHWARAN, G SIVAKMAR, M MOHAN and M S YANDIGERI National Bureau of Agriculturally Important Insects, P.B. No. 2491, HA Farm Post, Bellary Road, Bangalore 560024, Karnataka, India (Received on 09 April 2013; Revised on 20 August 2013; Accepted on 23 September 2013) Insects, like other organisms, are susceptible to a variety of diseases caused by bacteria, viruses, fungi and protozoans, and these pathogens are exploited for biological control of insect pests through introductory or inundative applications. Microbial pathogens of insects are intensively investigated to develop environmental friendly pest management strategies in agriculture and forestry. In this paper, the scope for utilization of insect pathogens in pest management in the world and India is reviewed. The most successfully utilized insect pathogen is the bacterium, Bacillus thuringiensis (Bt) which is used extensively for management of certain lepidopteran pests. In India, mostly imported products of Bt kurstaki have been used, which are expensive and there is an urgent need to develop aggressive indigenous Bt strains against various pests. Baculoviruses comprising nuclear polyhedrosis virus (NPV) and granulosis virus (GV) have been successfully used as insect pathogens because of their high virulence and specificity. NPV and GV formulations are used for lepidopteran pests like Helicoverpa armigera (HaNPV) and Spodoptera litura (SlNPV) in India, besides Anticarsia gemmatalis NPV in Brazil, Lymanttria disper NPV, Orgyia pseudotsugata NPV in USA and GV of Pieris rapae in China. Lack of easy mass multiplication methods for the commercial production of baculoviruses calls for R&D to develop production in insect tissue cultures. -

No entanto, os poucos estudos sobre a espécie não são concordantes quanto a sua distribuição geográfica. A presente nota comunica a ocorrência de A. robusta nas restingas da Ilha de Guriri, norte do Espírito Santo. Esse novo dado permite afirmar que A. robusta não é endêmica da Baixada Fluminense, estando distribuída pelo menos nas restingas dos estados do Rio de Janeiro e Espírito Santo. PALAVRAS-CHAVE: Saúva, endemismo, restinga ABSTRACT - Atta robusta Borgmeier has been described as an endemic species from the lowlands of Rio de Janeiro State. However, the scarce studies carried out with species disagree in relation to its geographic distribution. In this note we describe the occurrence of A. robusta in the “restingas” of Guriri Island, north of Espírito Santo State. This occurrence makes clear that A. robusta is not endemic from Rio de Janeiro State, being distributed at least in “restingas” in Rio de Janeiro and Espírito Santo states.

The move towards biological control methods represents an important option to mitigate environmental impact linked with the use of insecticides for their control. Metarhizium acridum, a locust pathogenic fungus that gave excellent test results in controlling grasshoppers, was further developed as biopesticide. The stability of the manufactured biopesticide in operational conditions was tested. In the present study, the germination of spores and mycelial growth of M. acridum were higher at 28 °C and 33 °C. Higher temperatures led to a significant decrease of these biological parameters. The sporulation of M. acridum is abundant at 28 °C and 33 °C but was completely inhibited at 37 °C. Furthermore, M. acridum based biopesticide showed a good infection rate for the dry spores formulation for 3 months of storage in all test sites. In the oil formulation in contrast, infectivity rate dropped quickly to a very low level after one month storage in the inland sites and remained good in Dakar. High temperatures and low moisture, away from the coast were speculated to be the reasons. -
Genetic Diversity and Structure of Atta Robusta (Hymenoptera, Formicidae, Attini), an Endangered Species Endemic to the Restinga Ecoregion

Abstract The genetic diversity and structure of the ant Atta robusta were assessed by ISSR (inter-simple sequence repeats) in 72 colonies collected from 10 localities in the Brazilian states of Espírito Santo (48 colonies) and Rio de Janeiro (24 colonies). The ISSR pattern included 67 bands, 51 of them (76.1%) polymorphic. Analysis of molecular variance (AMOVA) revealed a high level (57.4%) of inter-population variation, which suggested a high degree of genetic struc- ture that was confirmed by UPGMA (unweighted pair-group method using an arithmetic average) cluster analysis. The significant correlation between genetic and geographic distances (r = 0.64, p < 0.05) indicated isolation that re- flected the distance between locations. Overall, the populations were found to be genetically divergent. This finding indicates the need for management plans to preserve and reduce the risk of extinction of A. robusta.

[email protected] ABSTRACT. Parasitoids of the endangered leafcutter ant Atta robusta Borgmeier in urban and natural areas. Hosts of parasitoids in urban areas may suffer from a double threat of habitat destruction by urbanization and parasitism pressure. Moreover, the parasitoids themselves might be at risk if they are specialists. Here, we studied whether Atta robusta (Hymenoptera, Formicidae), which is on the red list of Brazilian threatened species, suffers from higher parasitism pressure in an urban area compared to a natural one. In addition, we determined whether their specialist parasitoids, Eibesfeldtphora breviloba and Myrmosicarius exrobusta (Diptera, Phoridae), are in risk and evaluated whether they are influenced by habitat structure, temperature, humidity, ant traffic, and time of the day. The study was carried out in an urban park and in a natural protected area in the city of Rio de Janeiro. In each site we chose an open area and a closed area (forest) and sampled nine nests in each area. We found that parasitism pressure was similar in urban and natural areas, with the same two parasitoid species present in both areas.
