The role of semiochemicals originating from the aphid and predators were studied using a four arm olfactometer. At higher densities, aphids produce more alarm pheromone which would serve as kairomonal cues to the coccinellids so that it attracts more predators compared to lower density of aphid infestation. Cheilomenes sexmaculata (Fabricius) showed more attraction towards high aphid population densities (150) of Aphis craccivora Koch and C. sexamculata showed a negative response towards the eggs of these predators in aphid colonies in the olfactometer.Keywords

A purposive survey was undertaken to explore the predatory mite fauna associated with the vegetable crops viz., amaranthus, brinjal, bittergourd, chilli, cowpea, coccinia, cucumber, snakegourd and snap melon from major vegetable growing tracts of Thrissur district, Kerala during 2014 - 2015. A total of 9 specoes of mites belonging to the family Phytoseiidae were identified. Faunal studies revealed highest diversity of mites on brinjal comprising nine species and the least diversity on bittergourd, chilli, cucumber, snap melon and snakegourd with four species each. Neoseiulus longispinosus Koch was recognised to be the predominant predatory mite species on all the vegetables. The other important phytoseiid predators recorded in the study include Amblyseius paraaerialis Muma, Amblyseius largoensis (Muma), Paraphytoseius orientalis Narayanan, Euseius macrospatulatus Gupta, Euseius sp. nr. prasadi, Typhlodromips syzygii Gupta, Phytoseius intermedius Evans and Scapulaseius sp.Keywords

An extensive survey was undertaken to explore the diversity of fauna of Scymnini associated with sucking pests viz., mealybugs, aphids and whiteflies on fruits, vegetables, plantation crops, ornamentals and other associated plants across Kerala during 2015-17. Scymnini along with associated prey were collected, and in the laboratory, beetles were dissected to study the male genitalia for identification, while prey were identified by the expert in the concerned taxa at NBAIR. The study recorded 14 species of Scymnini in five genera associated with 19 species of prey (12 mealybugs, 5 aphids and 2 whiteflies). The five genera include Axinoscymnus, Cryptolaemus, Horniolus, Nephus and Scymnus. Scymnus, the predominant genus was represented by three subgenera viz., S. (Scymnus), S. (Pullus) and S. (Neopullus). S.(Pullus) coccivora Ayyar recorded the maximum prey range of six species of mealy bugs. Nephus regularis (Sicard) was recorded for the first time in Kerala. The study identified Toxoptera odinae (van der Goot) as a new prey record for S. (P.) pyrocheilus Mulsant.Keywords

Cucumber is one of the most preferred crops grown in polyhouses of Kerala. However, incidence of spider mite, Tetranychus urticae Koch, 1836 as emerged as an important limiting factor for cucumber cultivation in the polyhouses. Increasing concern over the abuse of acaricides for mite management in polyhouses has necessitated development of alternative strategy with emphasis on biological control. The phytoseiid mite, Neoseiulus longispinosus (Evans, 1952) which has a wide distribution and has the ability to adapt to warm temperatures can be a potent candidate against tetranychid mites. To identify the optimum predator: prey ratio of N. longispinosus to T. urticae for effective management of spider mites, experiments were conducted both in the laboratory as well as polyhouse using a range of ratios. In the laboratory, the experiment was carried out on excised cucumber leaves maintained on moist sponge in plastic trays. Gravid females of N. longispinosus were released to 100 mixed stages including eggs, nymphal stages and adults of prey on cucumber leaves at predator: prey ratios of 1:5, 1:10, 1:20, 1:25, 1:33, 1:50 and 1:100. In the polyhouse, hundred mixed stages of T. urticae were released on four leaf stage of twenty days old cucumber plants at the rate of 25 mites/leaf, followed by the release of gravid females of N. longispinosus at predator: prey ratios of 1: 20, 1: 25, 1: 33 and 1:50. Laboratory studies showed that, at ratios of 1:5 and 1:10, the prey population was significantly reduced by third day. The prey was completely eliminated by seventh and tenth day at ratios 1:5 and 1:10 respectively. Ten days after the release, the prey population at ratios, 1 20, 1:25 and 1:33 were on par with that of 1:5 and 1:10. In the polyhouse, the predator: prey ratios of 1:20 and 1:25 were significantly superior in reducing the population of T. urticae on cucumber. The present study has revealed the potential of the predatory mite, N. longispinosus as a biocontrol agent against T. urticae on cucumber in polyhouse.Keywords
