On the Types of Oligosita species from India (Hymenoptera: Chalcidoidea: Trichogrammatidae), with some records
MOHAMMAD HAYAT 5-18
ABSTRACT. Notes are provided on the types of Oligosita species present in the ZDAMU. Three new specific synonymies are proposed, viz. O. ruficorpa Yousuf and Shafee with O. novisanguinea Girault; O. aligarhensis Yousuf and Shafee and O. kasimpurensis Yousuf and Shafee with O. meerutensis Yousuf and Shafee. Four species (O. sanguinea (Girault); O. novisanguinea Girault; O. yasumatsui Viggiani and Subba Rao; O. brevicilia Girault) are newly recorded from India and a key is provided for 16 of the 17 Indian species.
Aphids (Homoptera: Aphididae) and their host plants from Karnataka, India
SUNIL JOSHI 19-32
ABSTRACT – A total 66 aphid species under 38 genera belonging to seven subfamilies were recorded infesting 219 plant species belonging to 166 genera in Karnataka during an intensive survey for aphids during 2000-2003. The subfamily Chaitophorinae was recorded for the first time from south India. Eighteen species were recorded for the first time from Karnataka, of which six species were new records from south India. Aphis gossypii Glover (55 host plants), Aphis craccivora Koch (50 host plants), Hysteroneura setariae (Thomas) (22 host plants), Aphis spiraecola Patch (20 host plants), Myzus persicae (Sulzer) (20 host plants), Toxoptera aurantii (Boyer de Fonscolombe) (17 host plants), Tetraneura nigriabdominalis (Sasaki) (16 host plants) and Aphis nerii (Boyer de Fonscolombe) (14 host plants) were observed to be highly polyphagous, infesting more than 10 species of host plants. Most of the host plants surveyed were observed to be infested by less than five species of aphids except Oryza sativa Linn., Eleusine coracana (Linn.) Gaertn. (6 species each), Cajanus cajan (Linn.) Millsp., Solanum melongena Linn., Vicia faba Linn., Zea mays Linn. and Medicago sativa Urban (5 species each). Twenty-seven new host plants were recorded from India for various aphid species.
Morphometrics of the Genus Rhinolophus Lacepede From Northern Western Ghats of Maharashtra
VISHAKHA KORAD, RUPESH N. RAUT AND MALHAR S. PRADHAN 33-45
Morphometrical study of species of Rhinolophus Lacepede from Northern Western Ghats of Maharashtra was carried out. The study was based on 21 morphological characters. Multivariate analyses of allometrically scaled cranial, dental and external character measurements were carried out. Discriminant factor analysis (DFA) showed formation of four clusters for individual species. Support to DFA analysis with phylogenetic tree is given. Presence of Rhinolophus cognatus Andersen in the Western Ghats for the first time is predicted.
Checklist of Terebrantia (Thysanoptera) Recorded from Karnataka, India
KAOMUD TYAGI AND VIKAS KUMAR 41-48
ABSTRACT – 59 named species in 40 genera in three families (Aeolothripidae, Stenurothripidae and Thripidae) of the suborder Terebrantia (Order Thysanoptera) are listed from Karnataka (India). Twenty-five species are being reported for the first time from Karnataka; one species in Aeolothripidae and twenty-four in Thripidae. Synonymies, distribution and details for material studied are provided for new records.
Identity and Distribution of Bactrocera caryeae (Kapoor) (Insecta: Diptera: Tephritidae) – A Species under the Bactrocera dorsalis complex in India
- RAMANI, K. J. DAVID, C. A. VIRAKTAMATH AND A. R.V. KUMAR 49-57
ABSTRACT – Among the species complexes in the family Tephritidae the Oriental fruit fly, Bactrocera dorsalis (Hendel) complex is of great importance, because of its economic significance and difficulty in identification. The Bactrocera dorsalis complex contains about 76 described species. Some of the species in the complex like B. caryeae, present in India and Sri Lanka, pose threats to export of fruits because of trade restrictions and invasion threats. The occurrence of Bactrocera (Bactrocera) caryeae (Kapoor) in India, its present distribution, recorded hosts along with a discussion on the distinguishing characters are presented. The holotype and allotype of caryeae were examined and comments included. The holotype of Bactrocera (Bactrocera) poonensis (Kapoor) was examined and its confusing status in published literature clarified. The species has been removed from the synonymy with Bactrocera (Bactrocera) caryeae (Kapoor) and placed in synonymy with Bactrocera (Bactrocera) correcta (Bezzi).
A New Species of Gonatocerus Nees (Hymenoptera: Chalcidoidea: Mymaridae) from Karnataka, India
ANKITA GUPTA AND J. POORANI 59-62
ABSTRACT – Gonatocerus similis sp.nov. (Hymenoptera: Chalcidoidea: Mymaridae) belonging to the asulcifronsgroup, from Karnataka, India, is described and illustrated. The diagnostic characters of G. similis in relation to the other species of the asulcifrons-group and species of other groups from India are discussed in brief: First funicular segments shorter than pedicel and second funicular segment; sixth and seventh funicular segments yellowish white; fore wing disc with 5 microtrichia; fore coxae yellowish; absence of subantennal sulci on head; antenna with funicular segments 2-8 subequal and clava with more than 11 sensillae.
Studies on the biology of bamboo locust, Choroedocus illustris Walker (Acrididae: Orthoptera) under laboratory conditions
- R. KHAN 63-69
ABSTRACT – The field collected Choroedocus illustris was reared in wooden cages in a thermo- regulated insectary. Oviposition behaviour was observed to be typical acrididian pattern. Eggs were incubated at 27 ± 1°C and 37 ± 1°C and 70±5% R.H. The hoppers completed their development through five nymphal stages. The nymphal duration for different experimental set-ups are as follows – At 37 ± 1°C it was 49.7 days in isolated/Male, 49.1 days in crowded/Male, 51 days in isolated/Female, 50.1 in crowded/Female when fed on Z. mays and 60 days in isolated/Male, 59.9 days in crowded/Male, 60.7 days in isolated/Female, 59.9 days in crowded/Female condition when fed on C.dactylon; At 27 ± 1°C it was 53.9 days in isolated/Male, 51.7 days in crowded/Male, 56.1 days in isolated/Female, 51 days in crowded/Female condition when they were fed on Z. mays and 63.7 days in isolated/Male, 63.2 days in crowded/Male, 65.9 days in isolated/Female, 64.7 days in crowded/Female condition when fed on C. dactylon.
