“…In some other studies, topical application of the insecticides on the termites showed the following order of efficacy: chlorpyrifos > bifenthrin > flufenoxuron > thiamethoxam > imidacloprid (Ahmed et al, 2006). The latter may appear slow acting termiticide (Rasib et al, 2018), nevertheless, contact was once and residual action is not perceived in topical application. However, in another study, Rasib et al (2017) found imidacloprid to be is more toxic than fipronil based on LC50 values.…”

“…Soil barrier is an effective mean to arrest march of termites towards valuables in household and buildings (Nunes & Nobre, 2001;Ahmed et al, 2006;Ahmed & Qasim, 2011). Besides other non-chemical materials, insecticides such as chlorpyrifos, bifenthrin and fipronil have been commonly advocated for pre-or post-construction barriers in the soil (Aihetesham et al 2018). Chlorpyrifos in generic form Termikill and several other trade names or brand such as Dursban, Boimax, and Larsban has been extensively used as termiticide for the last two decades in Pakistan (Manzoor & Pervez, 2014, Sohail et al 2015.…”

Subterranean termites are considered to be one of the most destructive termites in urban areas in Pakistan. Different types of insecticides have been used to control subterranean termites. The present studies were conducted to evaluate the comparative persistency and effectiveness of Termiban (imidacloprid 5 SC) and Chlorpyrifos (40 EC) against subterranean termites in the three type of soils (sand, silt and clay) at different time interval. Two different concentrations (100 and 200 ppm) of selected insecticides were prepared and applied to soil in petri plates and termite were released at different time interval to record mortality. Results showed that at each time interval and concentration, mortality of termite was non-significantly different for both insecticides. When persistency of insecticides was tested under closed condition, results showed that lowest weight loss (8.60%) of wood was observed in Termiban treated soil at 200 ppm which was significant different from rest of the treatments. Similarly, under open conditions, at each time interval, there was significant more mortality of termites in soil treated with Termiban compared to Chlorpyrifos.

“…This species is highly problematic in agriculture, forestry and buildings (Akhtar & Kausar, 1991;Uys, 2002). There are some laboratory and field studies that have been conducted against this particular species involving different insecticides but with different objectives and methodologies (Kumawat, 2001;Ahmed et al, 2007;Bhagawati et al 2017;Rasib et al 2018). Previous studies aimed to determine if a repellent concentration(s) of a specific insecticides or plant extract for creating soil barrier treatment would keep the termites away from the structure or building thus killing only a small fraction of termite individuals.…”

Fungus-growing termites are important pests for buildings and agriculture in Asia and Africa. This study assessed four insecticides (fipronil 5% SC, imidacloprid 20 SL, thiamethoxam 25 WG and chlorfenapyr 360 SC) for their toxicity and repellency to the fungus-growing termite, Odontotermes obesus (Rambur, 1842) (Blattodea: Termitidae: Macrotermitinae). The study was conducted at Ghazi University, Dera Ghazi Khan, Pakistan from September-October, 2016 and was undertaken to identify effective termiticides along with their optimal concentrations for future use in baits and localized treatments. The chemicals assessed were differed significantly in their toxicity. Chlorfenapyr and thiamethoxam were more toxic and faster acting with lower LC50 and LT50 values than imidacloprid and fipronil. The four chemicals were statistically similar at each concentration. Odontotermes obesus was not repelled by 0-20 mg/l chlorfenapyr, 0-40 mg/l fipronil, 0-80 mg/l imidacloprid or 0-20 mg/l thiamethoxam. These results suggest that chlorfenapyr, imidacloprid and thiamethoxam may be used as soil termiticides, whereas fipronil can be used both as soil termiticide and in termite baiting programs.
