“…At the end of each drying time, blocks were removed and put on a concrete surface in the underground pits (Fatima et al 2015) to determine moisture gain. Pits were also meant to expose blocks to termites' access and O. obesus was termites' species in this particular site of Postgraduate Agriculture Research Station, Jhang Road, Faisalabad.…”

The relationship between drying and hygroscopic ability of Crateva adansonii and Populus deltoides woods to resist feeding by Odontotermes obesus was studied. Woods were dried under the sun and in the oven for a range of 5-25 days and then these were exposed to termites for 25 days in underground pits in Randomized Complete Block Design pattern with five replications. Results showed that lowest moisture gain was observed at a short time for drying with each method. Weight loss after termites' exposure was more in less dried sap and heartwood of either plant species. The practical implication of these results is discussed.

“…On the other hand, susceptible wood species can be made durable by the application of certain synthetic preservatives. Synthetic wood preservatives, despite their advantages, pose environmental concerns because of their toxicity and persistence (Ahmed et al 2014, 2016, 2017, Fatima et al 2015. There is a need for wood preservation strategies with lower environmental impacts and reduced effects on non-target species.…”

Termiticide, repellent and antifeedant activities of extracts from Pongamia pinnata wood were evaluated against Coptotermes heimi (Wasmann) at three different concentrations preceded by a preliminary choice and no-choice tests for natural resistance of tested wood. Termites' mortality was determined in each case of extract and solvent treated Whatman fi lter paper. Finally, wooden blocks of poplar (19×19×19 mm) were treated with extracts and respective solvents and exposed to termites in the fi eld for 28 days. Minimum mean weight loss was observed in dried P. pinnata (6.38%), followed by fresh P. pinnata in choice tests. In no-choice tests, dried P. pinnata was comparatively resistant with a weight loss of 12.37%, followed by fresh P. pinnata and P. deltoides. In toxicity bioassay, ethyl acetate-based wood extracts caused the highest mortality (41.66%), followed by petroleum ether, hexane, and water extracts at 10 mg/ ml concentration. Similarly, ethyl acetate-based extracts showed maximum repellency (100%) followed by petroleum ether extracts at 10 mg/ml and ethyl acetate at 5 mg/ ml after 60 min of termite exposure. Minimum wood losses were observed in woods treated with ethyl acetate extracts compared to control and other treatments in fi eld experiments.
