| Summary, etc. | The availability of Medicinal plants is mainly from the natural resources <br/>like forests and .waste lands. Today farmers of Kerala are taking up cultivation of <br/>medicinal plants in an organised manner. A thorough survey conducted in three <br/>different localities such as herbal gardens of College of Horticulture, Vellanikkara, <br/>Thycaud Moos Arya Vydyasala, Chuvannamannu and Kottakkal Arya Vydyasala <br/>Kottakkal being listed had resulted in alarming informations. Survey was done just on <br/>ten economically important' medicinal plants, viz., Neelamari, Adapathiyan, <br/>Chethikoduveli, Thippali, Vallippala, Thulsi, Kacholam, Karalakom, Kasthurivenda <br/>and Madhunashini. <br/>Complete survey of selected ten medicinal plants indicated the presence of <br/>57 different species of insect pests of which, 44 species are new reports, <br/>In Neelamari rate of infestation by psyllids was to a major level. Typical <br/>symptoms of 'die back' had been observed. The five minor species include webbers, <br/>flower beetles, treehoppers, pentatomids and alydids. The predatory coccinellids, ants <br/>and spiders associated with the psyllids were the other new reports. Spiders were <br/>observed to prey upon the coccinellids which inturn were psyllid predators. <br/>Occurrence of milkweed butterfly on adapathiyan was to a major level. Tachinid flies <br/>were found to parasitise the butterfly larvae. Chethikoduveli heavily infested by <br/>citraka looper was a major one. A microlepidopteran belonging to the family <br/>Cl <br/>Grassillaridae was found infesting on Thippali spikes. Spike thrips, thippali mealy <br/>bugs were the other minor pests. Vallippala semilooper, a key pest was ranked as a <br/>completely defoliating one. Its biology studied reveals that egg period to be three days, <br/>larval instars as first, second, third, fourth and fifth, prepupal and pupal duration of 2, <br/>2, 3, 3, 2, 1, 6.4 ± 0.1956 days respectively. Total life cycle was found to, be 22.4 ± <br/>0.1956 days. Tylophoran bug and Asclepidian beetle which were first reports. Glossy <br/>tiger in Vallippala was found on a major level. Lacewing bug were found to be major <br/>one in Tulasi. But there were numerous minor pests as Tulasi leaf webber, <br/>grasshopper, ash weevil, Pentatomid bugs and Coried bugs. Kacholam were infested <br/> <br/>Cl <br/> <br/><br/>by Lema beetle, black hairy caterpillar and swarming caterpillar which were the minor <br/>ones. Karalakom butterfly were ranked as key pest. Its biology and management using <br/>botanical pesticides were studied. The egg, larval duration of first, second, third and <br/>fourth instars prepupal and pupal stages had a duration of8.2 ± 0.1405, 7.7 ± 0.1768, <br/>7.8 ± 0.1749, 9, 7.9 ± 0.2422,1,14.8 ± 0.1749 days respectively. Total life cycle was <br/>found to be that 56.1 ± 0.5248 days. Flea beetles were found to make the leaf papery <br/>thin. In Kasthuri venda there were two major and 11 minor pests. The major ones were <br/>found to be the pests of okra too. Major ones are shoot and fruit borer and leaf roller. <br/>Defoliator in Madhunasini were parasitised by a Hymenopteran belonging to the <br/>family Braconidae. Moth bugs and three types of passive visitors observed were also <br/>new reports. <br/>As the influence of weather parameters on the distribution of key pests <br/>were studied, it was observed that with a rise in temperature there was a flare up on <br/>Vallippala semilooper and Karalakom butterfly population. With decrease in <br/>temperature the reduction in pest population was common for both the pests. When the <br/>relative humidity was taken into account, it was evident that decrease in Vallippala <br/>semilooper population was indirectly proportional to the relative humidity but it was <br/>directly proportional to the spread of Karalakom butterfly. When the influence of wind <br/>speed was taken into consideration it was found that wind speed had no direct <br/>influence on Vallippala semilooper distribution but with regard to Karalakom butterfly <br/>the spread was more with an increased wind speed. While studying the effects of total <br/>sunshine hours in a day on the pest spread, it was clear that there was an increase in <br/>Vallippala semilooper distribution and a reduction in Karalakom butterfly population <br/>with increased sunshine hours. <br/>The evaluation of botanical pesticides revealed a maximum antifeedancy <br/>with Neem Kernel Suspension (NKS) followed by neem leaf extracts. In the case of <br/>Vallippala semilooper hyptis ranked as the next best. While it was yellow oleander for <br/>Karalakom butterfly. These eco-friendly approaches are new records. <br/><br/> |
