Three new species of the genus Aleurotrachelus Quaintance & Baker are described, A. diploclisiae sp. nov. on Diploclisia glaucescens, A. fici sp. nov. on Ficus virens and A. psydraci sp. nov. on Ps...

Antifeedant activity of Capparis decidua extracts has been studied against a ployphagous lasiocampid moth Streblote (=Taragama) siva commonly known as Babul defoliator and infesting a number of tree species throughout the arid tracts of Indian Thar Desert. Wood, bark, branch and fruits of C. decidua collected from suburbs of Jodhpur (Rajasthan, India) were extracted with petroleum ether and chloroform and extractive values were determined. All extracts were tested at 0.01, 0.05 and 0.1 % concentrations for their antifeedant efficacy against S. siva. Significant antifeedant activity against the moth was recorded at 1 % concentration of the all the extracts. Seed extract however have shown the highest antifeedant activity.

Eleven new species of the genus Aleuroclava Singh viz., A. celtise, sp. nov. (Tamil Nadu: Kodaikanal); A. combifornis, sp. nov. (Andhra Pradesh: Visakhapatnam); A dipterocarpi, sp. nov. (Kerala: Pamba); A. nothapodytese, sp. nov. (Karnataka: Chikmagalur); A. palakkadensis, sp. nov. (Kerala: Singampara); A. pambaensis, sp. nov. (Kerala: Pamba); A. paracrotone, sp. nov. (Kerala: Nellayampathi); A. premnae, sp. nov. (Tamil Nadu: Thaniparai); A. rhamnacei, sp. nov. (Tamil Nadu: Bhima falls); A. scolopiae, sp. nov. (Kerala: Karadipara); and A. viraktamathi, sp. nov. (Tamil Nadu: Kumarapuram) are described and illustrated. The names A. indicus Meganathan & David and A. papillata Dubey & Sundararaj retained and additional notes provided for A. goaensis Jesudasan & David and A. manii (David). This brings the number of Indian species of Aleuroclava to 62. Also, new hosts recorded for the Indian fauna.

Three whiteflies namely Singhius meiogynea, sp. nov. breeding on Meiogyne pannosa, S. pandalamensis, sp. nov. on Macaranga peltata and Aporusa sp., and S. philomenae, sp. nov. on Mussaenda frondosa described and illustrated. All the species of the genus Singhius listed and a key to the species given.

Cockerelliella kudremukhensis, sp. nov. breeding on Syzygium sp. and Pseudcockerelliella curvata, gen. et. sp. nov. breeding on Holigarna grahamii are described and illustrated. Pseudcockerelliella, gen. nov. resembles Cockerelliella Sundararaj & David, but differs distinctly in the cephalothoracic suture pattern separating the dorsal disc from submedian area, longitudinal moulting suture not reaching margin and transverse moulting suture extending beyond submarginal furrow, and presence of very narrow thoracic and caudal tracheal furrows without any marking. The species of Cockerelliella are listed and a key to the known species is given. A key to the puparia of whitefly genera in India is also given.

Five new species of Dialeurolonga Dozier, viz., D. davidi Dubey & Sundararaj, D. kumargiriensis Dubey & Sundararaj, D. multipori Dubey & Sundararaj, D. multituberculata Dubey & Sundararaj and D. pseudocephalidistincta Dubey & Sundararaj from India are described and illustrated. A key to the Indian species of Dialeurolonga is given.

Eight new species of the genus Aleuroclava Singh viz., A. calicutensis, sp. nov. (Kerala: Calicut), A. calycopteriseae, sp. nov. (Karnataka: Kudremukh), A. davidi, sp. nov. (Tamil Nadu: Jamunamarathur hills), A. doddabettaensis, sp. nov. (Tamil Nadu: Doddabatta), A. kudremukhensis, sp. nov. (Karnataka: Kudremukh), A. martini, sp. nov. (Karnataka: Kudremukh), A. papillota, sp. nov. (Karnataka: Kudremukh), and A. ramachandrani, sp. nov. (Karnataka: Unachali falls) are described and illustrated. Two new combinations Aleurclava murrayae (Singh), comb. nov. and Aleuroclava psidii (Singh), comb. nov. are proposed. This bring the number of Indian species of Aleuroclava to 49. New hosts have been recorded for the Indian species of Aleuroclava.

The whitefly genus Aleurocanthus Quaintance & Baker is represented by 25 species in India. In the present paper six new species viz., A. bangalorensis, A. flrmianae, A. goaensis, A. satyanarayani, A. terminaliae, and A. vindhyachali are described and illustrated. A key to Indian species of Aleurocanthus is given.

The genus Aleuroclava Singh was represented in India so far by 22 species. Fourteen new species are described here from India and a workable key to the Indian species of the genus is given.
