Trigona Subgenus Duckeola in Colombia (Hymenoptera: Apidae)

The stingless bee Trigona subgenus Duckeola is an uncommon Amazonian taxon consisting of only two species (Michener, 1990, 2000). Smith-Pardo and Engel (2001) extended the range of Duckeola, which was previously known from Brazil, based on six workers collected in Bolivia and French Guiana. The subgenus Duckeola was also included in a checklist of the stingless bee genera occurring in Colombia by Nates-Parra (1990); however, other than listing Duckeola, Nates-Parra (1990) did not provide any data on the material examined and depositary collection. Although Smith-Pardo and Engel (2001) were not able to examine the Colombian specimens, they referred to this record as a possible misidentification with the genus Cephalotrigona. Recently, one of us (VG) examined and compared the Colombian specimens with those from Brazil and French Guiana deposited at the Entomology Division, Natural History Museum, University of Kansas (SEMC). We confirm the specimens from Colombia are Trigona (Duckeola) ghilianii Spinola. Such specimens are deposited in the Laboratorio de Abejas in the Universidad Nacional de Colombia, Bogota (LABUN) and SEMC as indicated in the section below. Therefore, this note confirms the presence of Trigona (D.) ghilianii Spinola in the southern lowland forests of Colombia (Amazonia and Orinoquia regions), and this species can be added to the updated list of Colombian bees by Smith-Pardo (2003).

Douglas Frew Waterhouse, C.M.G. 3 June 1916 – 1 December 2000

Doug Waterhouse was a renowned entomologist, a fine scientist and an accomplished administrator. He worked within the Commonwealth Scientific Industrial Research Organisation (CSIRO) Division of Entomology for over 60 years, and was its Chief for 21 years until his retirement in 1981. Doug was responsible for many developments in insect and weed control, both in Australia and around the globe, especially in developing countries across Asia and the Pacific. He not only guided the Division to international prominence, but was also an ardent humanitarian whose work had beneficial effects in many neighbouring countries. Much of his ‘public good’ work was done as an Honorary Fellow (1981–2000). As well as his extensive entomological interests, Doug was active in other areas such as education and community services. He was the foundation Chairman of the Canberra College of Advanced Education and continued as Chancellor when it became the University of Canberra.

Description of a new species and records of two known species of Neostromboceros Rohwer from India (Hymenoptera: Symphyta: Tenthredinidae: Selandriinae)

Introduction Rohwer (1912) erected the genus Neostromboceros with Stromboceros metallica as its type species from Singapore. There are nine species already on record from Indian zoogeographic limits. Of these, six are described by Cameron (1888, 1899, 1902, 1907) viz., N. rothneyi, N. caeruleiceps, N. fuscinervis, N. pilicornis, N. trifoveatus and N. basilineatus, while two, N. indobirmanus and N. speciosus, by Malaise (1944) and one, N. laevis, by Konow (1898). Two species -N. rugifrons Malaise (1944) and N. tonkinensis Forsius (1931) -are recorded for the first time from the Indian region. The present text deals with the systematic description and illustrations of a new species along with the redescription of the two newly recorded species. To authenticate their status, each of them has thoroughly been compared with its closely related species. A special attention has been paid to study the population variations and sexual dimorphism. The types and paratypes will be deposited in the Pusa National Collection, Division of Entomology, Indian Agricultural Research Institute, New Delhi, India, after this work is published. The terminology used in the text is after Ross (1937, 1945) and Malaise (1945).

Description of three new species of Tenthredo Linnaeus from India (Hymenoptera: Symphyta: Tenthredinidae)

Introduction Tenthredo Linnaeus is one of the largest genera of the Tenthredinidae with more than 800 species described worldwide. The genus is represented by 153 species in the Indian subcontinent. After the revisionary work by Malaise (1945) on Southeast Asian Tenthredinoidea, numerous new species were added to this genus by Muche (1982; 1983), Singh (1985), Singh et al. (1985a,b), Singh and Saini (1987a,b,c; 1988a,b,c,d; 1994; 1995), Saini and Bharti (1996; 1997a,b; 1999), Saini and Vasu (1998a,b), Saini et al. (1998a,b), Vasu and Saini (1998) from India. Several new synonymies for the species of this genus were traced out by Vasu and Chambal (1997) and, Vasu and Saini (1999), while Vasu and Chambal (1998) associated females for the first time with their male counterparts of two species. In this paper three new species from this region are described and illustrated. Terminology used for description is after Ross (1937; 1945) and Malaise (1945). The type material will be housed at the Division of Entomology, Pusa National Collections, Indian Agricultural Research Institute, New Delhi, India.

Millennium bug

After global fears of computer snafus prompted billions of dollars of remedial action, the Y2K bug appears to have vanished with barely a trace. But on January l, taxonomists with the entomology division of Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) reported the discovery of an insect whose scientific and common names will be the “millennium bug.”

Developmental Stability and Fitness: The Evidence Is Not Quite So Clear

Commonwealth Scientific and Industrial Research Organisation, such an approach is that, on average, half of the studies Division of Entomology, GPO Box 1700, Canberra, ACT 2601, examined will show an effect, significant or not, in the Australia predicted direction. In order to reject the null hypothesis, greater than half the studies should support the predicSubmitted January 21, 1998; Accepted April 29, 1998 tion. For such an approach to be valid, all studies examined (i.e., votes cast) must specifically address the hypothesis of concern, in this case, the relationship between developmental stability and one or more individual fit

Leafhopper and planthopper vectors of rice viruses and their management in Nepal

Research on insect pests (including leafhoppers and planthoppers) in Nepal was initiated in 1956 by the Entomology Division and Plant Protection Units of the Department of Agriculture. More systematic work began after the establishment of a Rice Improvement Programme in 1972. Because of poor documentation and publication of research findings, it is difficult to assess the research efforts and achievements to date. The available research reports are mostly published in the proceedings of national seminars/workshops. They are used here to assess the current status of research on the occurrence and damage caused, distribution and composition, relative abundance, biology and management through chemicals. Much of past research has focused on insect surveys by light traps and sweep nets and the evaluation of insecticides and, since early 1990, some research on rice green leafhoppers (Nephotettix virescens and Nephotettix nigropictus) has begun to determine their relative abundance and population characteristics in relation to their potential as vectors of rice viruses. The challenges to pest management in general and some suggestions for future research needs are discussed, based on the present standing of agricultural research in the country

Preliminary observations on the anopheline mosquitoes of gomadiyagala a village in the north western province of Sri Lanka

Investigations on anopheline mosquitoes were carried out in Gomadiyagaladuring January-December 1989, primarily to gather base-line data in relationtoa collaborative study between the Entomology Division, Anti-Malaria Campaignand the Department of Zoology, University of Sri Jayewardenepura on thepotential for a genetic approach for malaria control in Sri Lanka. Eight anophelinespecies were recordedfrom adult catches and lavae sampled. An. subpictusAn. culicifacies and An. varuna were the most predominant species. The only stream with two tributaries in the study area was the permanentand very productive anopheline breeding habitat. Larval and adult anophelinedensities were related to the rainfall received. The larval densities recorded indrought periods were observed to be significantly higher than those recorded inrainy periods (t=4.087, p<O.Ol). August, September and October that recordedrelatively low larval and adult An. culicifacies densities appear to be suitabletimes for field releases of genetically altered An.culicifacies in the area for malariacontrol.

Scanning Electron Microscopical Observations of Pellioditis pellio (Nematoda: Secernentia)

Scanning electron microscopical (SEM) observations were made on the surface topography of the lips, papillae, amphids, excretory pore, vulva, anus, caudal alae, cuticular bosses, and annular rings of larvae and adults of Pellioditis pellio. Cobb formula measurements and morphological characteristics agreed with those described previously for this species. SEM reveals for the first time: (1) fleshy appearance of the vulva; (2) spherical excretory pore; (3) crescent-shaped vent; and (4) biradial arrangement of oral papillae, lateral alae, and transverse bosses on the cuticle. Similarities to Caenorhabditis elegans are noted, suggesting that P. pellio may be a useful model for comparative neuroanatomical studies. According to Andrassy (1983), the correct name for Rhabditis pellio is Pellioditis pellio (Schneider, 1866). Morphology, based on light microscopy, and life history of P. pellio were described (Goodchild & Irwin, 1971; Hertwig, 1920; Smyth, 1976; Thorne, 1961), and some studies of reproduction and chemoattraction were conducted (Somers et al., 1977a,b). We report here for the first time surface anatomical features, both of larvae and adults of P. pellio, based on scanning electron microscopical observations. MATERIALS AND METHODS A lumbricid oligochaete, Apporectodea caliginosa (Savigny, 1827), recovered from soil in Long Beach, Los Angeles County, California, U.S.A., was cut into three pieces. Segments 20-40 were severed further into 2-3 mm pieces, which then were placed on 1% nutrient agar (Difco Laboratories, Detroit, Michigan, U.S.A.) in a 100 x 15-mm plastic Petri dish. The anterior and posterior pieces were fixed in 70% ethanol for taxonomic identification. After two days, living rhabditiform larvae appeared on the agar and were transferred to clean dishes. In 2-3 days posttransfer, numerous male and female adults, larvae, and eggs appeared on the surface of the agar. Thereafter, worms were subpassaged twice weekly by transfer into new dishes. Flavobacteria associated with the transferred worms provided nutrients. Goodchild & Irwin (1971) reported that Pellioditis pellio is dioecious, and that Rhabditis anomala and R. maupasi are thelyotokous and parthenogenetic, respectively. To determine the reproductive pattern of our isolate, 10 adult 1 We thank Professor George Poinar, Division of Entomology and Parasitology, University of California, Berkeley, California, for confirming the identification of Pellioditis pellio, and Professor E.

A historical review and prospects of medical entomology research in Korea

Research activities of medical entomology in Korea can briefly be divided into three periods. During the first period (1910-1959), medical entomology research was initiated by Japanese workers, and then by U.S. Army Medical Unit personnels and a few Korean pioneers, who greatly contributed to establishing a foundation for medical entomology in Korea. During the second period (1960-1979), research activities were intensively carried out by the entomology team of the Central Malaria Eradication Service and staffs of the Division of Medical Entomology, National Institute of Health, who collaborated with WHO-Vector Ecology and Control Research Unit. During the third period (1980-present), studies were expanded to different research laboratories, such as Departments of Biology in College of Natural Sciences and Departments of Parasitology or others in Medical Schools, and study topics also became diverse. Out of 313 papers on Korean arthropods of medical importance, the majority were on mosquitoes (142 papers, 45.4%) and, next, on flies (53 papers, 16.9%). It is hard to see the future prospect of medical entomology research in Korea, since it looks pessimistic in some respects but optimistic in others. Korean medical entomologists may be quantitatively lacking, but not qualitatively behind.

Reflections on Some Insect Pest Control Procedures

Recently, I had an opportunity to visit with U.S. Department of Agriculture personnel at Mission, Tex. We discussed at length various problems associated with the sterile-male release program for the control of the New World screwworm fly, Cochliomyia hominivorax. Subsequently, the Genetics Society of Australia and the Commonwealth Scientific and Industrial Research Organization (CSIRO) joined in inviting me to be their foreign visitor for 1983. A good deal of my time in Australia was spent with M. J. Whitten (Director of the Division of Entomology, CSIRO, Canberra City, Australia) and his colleagues discussing the genetic control program being developed in Australia for the control of the sheep blowfly (Lucilia cuprina).
