| dc.description.abstract | Cashew nut shell liquid (CNSL), a by-product cashew nut processing
contains : anarcardic acid, cardanol, cardol & 2 – methyl cardol.
Cardanol & cardol were isolated from CNSL using chemical method
adopted from Kumar (2002).
Preservative was prepared by incorporating copper & chlorine in CNSL,
decarboxylated CNSL, cardanol & cardol. its efficacy against termites was
compared with commercially available termiticide (chlorpyrifos)
Test samples were coated with preservatives formulated, another batch
chlorpyrifos & control being wood blocks dipped in distilled water then
introduced at ant hills having a nest of Microcerotermes beesoni for 60
days.
Keen observations were made on feeding habits of termites on wood
samples of Juniperus procera, Grevilea robusta, & Pinus insularis.
% weight loss was calculated for each block after termite exposure & knife
test carried out to determine the extent of destruction. | en_US |
