Item Biology and biometric studies on Apis cerana indica F. and Apis mellifera ligustica Spin.(Department of Agricultural Entomology, College of Agriculture, Vellayani, 1998) Ajithkumar, T N; Rajan Asari, P AItem Dissipation ok quinalphos and monocrotophos residues in cardamom Capsules(Kerala Agricultural University, 1998) Thomas Biju Mathew; Visalakshi, A; Naseema Beevi, S; Rajan Asari, P A; Rajagopal, BThe paper describes the results of a field experiment conducted in the Cardamom Research Station, Pampadumpara, to study the dissipation of two insecticides used for controlling cardamom thrips and to fix their waiting periods. The results showed that the residues of quinalphos reached below the tolerance limit of 0.25 ppm within 23 to 24 days in fresh cardamom and within 20 to 21 days in cured cardamom. The corresponding periods for monocrotophos did not differ between fresh and cured cardamom (22 to 23 days) because of the systemic nature of the residues.Item Fusarium Moniliforme var Subglutinans Wollenw. & Reink., pathogenic to the spotted beetle Epilachna Vigintioctopunctata F(Kerala Agricultural University, 1978) Abraham Jacob; Suma Kuruvilla; Babu P Philip; Rajan Asari, P AItem New disease of the Indian honey bee, Apis Cerana Indica F., in Kerala(Kerala Agricultural University, 1992) Abraham Jacob; Rajan Asari, P A; Mohandas, NItem On the relative preference of Rattus rattus Linn to different varieties of tapioca(Kerala Agricultural University, 1978) Saradamma, K; Rajan Asari, P A; Nair, M R G KItem Phytophagous gastroped, opeas gracile (Hutton) as a pest of cowpea in Kerala(Kerala Agricultural University, 1973) Mammen, V; Rajan Asari, P AItem Saissetia nigra (Nietn) a pest on cassava(Kerala Agricultural University, 1978) Rajan Asari, P A; Johnson, JItem Studies on insect pests and diseases of rice earhead and their control(Department of Entomology, College of Agriculture, Vellayani, 1987) Annie Thomas; Rajan Asari, P AA random sample survey on insect pests and diseases infesting rice during, flowering stage was conducted to collect information on the occurence of pests and diseases on rice earhead of different localities in Trivandrum district. Itcould be observed that L.acuta was the most important pest occurring throughout the area surveyed . The importance of rice bug was further proved by the mean number of insect present in different localities. The mean number of rice bug varied from 0.25 to 2.45 which showed the existence of considerable variation according to localities and varieties. The high yielding varieties invariably were seen more susceptible to the pest infestation than the local cultivars.Item Use of lemongrass leaf infusion for the control of brinjal aphid(Kerala Agricultural University, 1974) Rajan Asari, P A; Thomas, M J
