The Role of Ants and Mammalian Herbivores on the Structure and Composition of Insect Communities Found on Canopies of Acacia Drepanolobium
African Journal of Agricultural Research Vol. 7(38), pp. 5317-5331, 2 October, 2012 Available online at http://www.academicjournals.org/AJAR DOI: 10.5897/AJAR12.059 ISSN 1991-637X ©2012 Academic Journals Full Length Research Paper The role of ants and mammalian herbivores on the structure and composition of insect communities found on canopies of Acacia drepanolobium S. K. Kuria 1* and M. H. Villet 2 1Department of Biological Sciences, Walter Sisulu University, P/B X1 Mthatha 5117, South Africa. 2Department of Zoology and Entomology, Rhodes University, Grahamstown 6140, South Africa. Accepted 4 June, 2012 Acacia drepanolobium Sjøstedt (Fabaceae) constitutes about 99% of the woody vegetation in the cotton soil ecosystem of Laikipia, Kenya. The tree has symbiotic association with four ant species that discourage large mammalian herbivores from feeding on it. However, there is no information as to whether these ants affect the community of canopy insects. Therefore, this study investigated the effect of the four ant species and differential vertebrate grazing and browsing pressures on the insect community inhabiting canopies of A. drepanolobium trees. Insect samples were collected using standard fogging and beating methods and identified to family and morphospecies. At the morphospecies level, the insect communities separated into two distinct groups, one comprised of samples collected from trees occupied by Crematogaster mimosae and Crematogaster nigriceps , and the other of samples obtained from trees inhabited by C. sjostedti and Tetraponera penzigi . However, differential vertebrate grazing and browsing patterns did not show any significant effect on the insect community occupying canopies of A. drepanolobium .

A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains, -

Brailovsky: A Revision of the Genus Amblyomia 475 A REVISION OF THE GENUS AMBLYOMIA STÅL (HETEROPTERA: COREIDAE: COREINAE: LEPTOSCELINI) HARRY BRAILOVSKY Instituto de Biología, UNAM, Departamento de Zoología, Apdo Postal 70153 México 04510 D.F. México ABSTRACT The genus Amblyomia Stål is revised and two new species, A. foreroi and A. prome- ceops from Colombia, are described. New host plant and distributional records of A. bifasciata Stål are given; habitus illustrations and drawings of male and female gen- italia are included as well as a key to the known species. The group feeds on bromeli- ads. Key Words: Insecta, Heteroptera, Coreidae, Leptoscelini, Amblyomia, Bromeliaceae RESUMEN El género Amblyomia Stål es revisado y dos nuevas especies, A. foreroi y A. prome- ceops, recolectadas en Colombia, son descritas. Plantas hospederas y nuevas local- idades para A. bifasciata Stål son incluidas; se ofrece una clave para la separación de las especies conocidas, las cuales son ilustradas incluyendo los genitales de ambos sexos. Las preferencias tróficas del grupo están orientadas hacia bromelias. Palabras clave: Insecta, Heteroptera, Coreidae, Leptoscelini, Amblyomia, Bromeli- aceae The neotropical genus Amblyomia Stål was previously known from a single Mexi- can species, A. bifasciata Stål 1870. In the present paper the genus is redefined to in- clude two new species collected in Colombia. This genus apparently is restricted to feeding on members of the Bromeliaceae, and specimens were collected on the heart of Ananas comosus and Aechmea bracteata. -
Lepidoptera of Albany Hill, Alameda Co., California
LEPIDOPTERA OF ALBANY HILL, ALAMEDA CO., CALIFORNIA Jerry A. Powell Essig Museum of Entomology University of California, Berkeley and Robert L. Langston Kensington, CA November 1999; edited 2009 The following list summarizes observations of Lepidoptera (moths and butterflies) at Albany Hill, Alameda Co., California, during 1995-1999. Data originate from about 75 daytime and crepuscular visits of 0.5 to 3.5 hrs, in all months of the year. All of the butterfly species and some of the moths were recorded by RLL, most of the moth species and their larval host plants by JAP. A total of 145 species is recorded (30 butterflies, 115 moths), a modest number considering the extent and diversity of the flora. However, many of the potential larval host plants may be present in too small patches to support populations of larger moths or butterflies. Nonetheless, we were surprised that colonies of some of the species survive in a small area that has been surrounded by urban development for many decades, including some rare ones in the East Bay region, as annotated below. Moreover, the inventory is incomplete. A more comprehensive census would be accomplished by trapping moths attracted to ultraviolet lights. In a habitat of this size, however, such survey would attract an unknown proportion of species from surrounding areas. Larval collections are indicated by date-based JAP lot numbers (e.g. 95C37 = 1995, March, 37th collection). Larval foods of most of the other species are documented in other populations. Host plants are recorded at Albany Hill for 75 species (65% of the moths, 52% of the total); the rest were observed as adults only. -
A Polyandrous Society in Transition: a CASE STUDY of JAUNSAR-BAWAR
10/31/2014 A Polyandrous Society in transition: A CASE STUDY OF JAUNSAR-BAWAR SUBMITTED BY: Nargis Jahan IndraniTalukdar ShrutiChoudhary (Department of Sociology) (Delhi School of Economics) Abstract Man being a social animal cannot survive alone and has therefore been livingin groups or communities called families for ages. How these ‘families’ come about through the institution of marriage or any other way is rather an elaborate and an arduous notion. India along with its diverse people and societies offers innumerable ways by which people unite to come together as a family. Polyandry is one such way that has been prevalent in various regions of the sub-continent evidently among the Paharis of Himachal Pradesh, the Todas of Nilgiris, Nairs of Travancore and the Ezhavas of Malabar. While polyandrous unions have disappeared from the traditions of many of the groups and tribes, it is still practiced by some Jaunsaris—an ethnic group living in the lower Himalayan range—especially in the JaunsarBawar region of Uttarakhand.The concept of polyandry is so vast and mystifying that people who have just heard of the practice or the people who even did an in- depth study of it are confused in certain matters regarding it. This thesis aims at providing answers to many questions arising in the minds of people who have little or no knowledge of this subject. In this paper we have tried to find out why people follow this tradition and whether or not it has undergone transition. Also its various characteristics along with its socio-economic issues like the state and position of women in such a society and how the economic balance in a polyandrous family is maintained has been looked into. -

Bacterial endosymbionts are common across insects, but we often lack a deeper knowledge of their prevalence across most organisms. Next-generation sequencing approaches can characterize bacterial diversity associated with a host and at the same time facilitate the fast and simultaneous screening of infectious bacteria. In this study, we used 16S rRNA tag encoded amplicon pyrosequencing to survey bacterial communities of 310 samples representing 221 individuals, 176 colonies and 95 species of ants. We found three distinct endosymbiont groups—Wolbachia (Alphaproteobacteria: Rickettsiales), Spiroplasma (Firmicutes: Entomoplasmatales), -
Evaluation of the Chemical Defense Fluids of Macrotermes Carbonarius
www.nature.com/scientificreports OPEN Evaluation of the chemical defense fuids of Macrotermes carbonarius and Globitermes sulphureus as possible household repellents and insecticides S. Appalasamy1,2*, M. H. Alia Diyana2, N. Arumugam2 & J. G. Boon3 The use of chemical insecticides has had many adverse efects. This study reports a novel perspective on the application of insect-based compounds to repel and eradicate other insects in a controlled environment. In this work, defense fuid was shown to be a repellent and insecticide against termites and cockroaches and was analyzed using gas chromatography-mass spectrometry (GC– MS). Globitermes sulphureus extract at 20 mg/ml showed the highest repellency for seven days against Macrotermes gilvus and for thirty days against Periplaneta americana. In terms of toxicity, G. sulphureus extract had a low LC50 compared to M. carbonarius extract against M. gilvus. Gas chromatography–mass spectrometry analysis of the M. carbonarius extract indicated the presence of six insecticidal and two repellent compounds in the extract, whereas the G. sulphureus extract contained fve insecticidal and three repellent compounds. The most obvious fnding was that G. sulphureus defense fuid had higher potential as a natural repellent and termiticide than the M. carbonarius extract. Both defense fuids can play a role as alternatives in the search for new, sustainable, natural repellents and termiticides. Our results demonstrate the potential use of termite defense fuid for pest management, providing repellent and insecticidal activities comparable to those of other green repellent and termiticidal commercial products. A termite infestation could be silent, but termites are known as destructive urban pests that cause structural damage by infesting wooden and timber structures, leading to economic loss. -

A Sacrificial Millipede Altruistically Protects Its Swarm Using a Drone
www.nature.com/scientificreports OPEN A sacrificial millipede altruistically protects its swarm using a drone blood enzyme, mandelonitrile Received: 05 January 2016 Accepted: 29 April 2016 oxidase Published: 06 June 2016 Yuko Ishida1,2, Yasumasa Kuwahara1,2, Mohammad Dadashipour1,2, Atsutoshi Ina1,2, Takuya Yamaguchi1,2, Masashi Morita1,2, Yayoi Ichiki1,2 & Yasuhisa Asano1,2 Soldiers of some eusocial insects exhibit an altruistic self-destructive defense behavior in emergency situations when attacked by large enemies. The swarm-forming invasive millipede, Chamberlinius hualienensis, which is not classified as eusocial animal, exudes irritant chemicals such as benzoyl cyanide as a defensive secretion. Although it has been thought that this defensive chemical was converted from mandelonitrile, identification of the biocatalyst has remained unidentified for 40 years. Here, we identify the novel blood enzyme, mandelonitrile oxidase (ChuaMOX), which stoichiometrically catalyzes oxygen consumption and synthesis of benzoyl cyanide and hydrogen peroxide from mandelonitrile. Interestingly the enzymatic activity is suppressed at a blood pH of 7, and the enzyme is segregated by membranes of defensive sacs from mandelonitrile which has a pH of 4.6, the optimum pH for ChuaMOX activity. In addition, strong body muscle contractions are necessary for de novo synthesis of benzoyl cyanide. We propose that, to protect its swarm, the sacrificial millipede also applies a self- destructive defense strategy—the endogenous rupturing of the defensive sacs to mix ChuaMOX and mandelonitrile at an optimum pH. Further study of defensive systems in primitive arthropods will pave the way to elucidate the evolution of altruistic defenses in the animal kingdom. Swarm-forming animals have unique defense systems for protection. -
Polygynandry, Extra-Group Paternity and Multiple-Paternity Litters In
Molecular Ecology (2007) 16, 5294–5306 doi: 10.1111/j.1365-294X.2007.03571.x Polygynandry,Blackwell Publishing Ltd extra-group paternity and multiple-paternity litters in European badger (Meles meles) social groups HANNAH L. DUGDALE,*† DAVID W. MACDONALD,* LISA C. POPE† and TERRY BURKE† *Wildlife Conservation Research Unit, Department of Zoology, University of Oxford, Tubney House, Abingdon Road, Tubney OX13 5QL, UK, †Department of Animal and Plant Sciences, University of Sheffield, Western Bank, Sheffield S10 2TN, UK Abstract The costs and benefits of natal philopatry are central to the formation and maintenance of social groups. Badger groups, thought to form passively according to the resource dispersion hypothesis (RDH), are maintained through natal philopatry and delayed dispersal; however, there is minimal evidence for the functional benefits of such grouping. We assigned parentage to 630 badger cubs from a high-density population in Wytham Woods, Oxford, born between 1988 and 2005. Our methodological approach was different to previous studies; we used 22 microsatellite loci to assign parent pairs, which in combination with sibship inference provided a high parentage assignment rate. We assigned both parents to 331 cubs at ≥ 95% confidence, revealing a polygynandrous mating system with up to five mothers and five fathers within a social group. We estimated that only 27% of adult males and 31% of adult females bred each year, suggesting a cost to group living for both sexes. Any strong motivation or selection to disperse, however, may be reduced because just under half of the paternities were gained by extra-group males, mainly from neighbouring groups, with males displaying a mixture of paternity strategies. -

I am very impressive for his meticulous attitude for scientific research. I benefited greatly from his valuable and illuminating suggestions for my research. It is also very touching for Dr. Henderson’s patience for my preliminary and sometimes “crazy” ideas. Also, he always could “see” what I ignored. For example, when I unintentionally talked about an observation that soldier and worker termites run in different directions after disturbance, he immediately pointed out the potential value to continue studying this and gave me valuable suggestions in the experiment.
