Garlic Alium sativium (L.) Volatile Oils as Fumigant for the Control of the Red floor beetle Tribolium castaneum (adult)

Mahgoub Ishag A.alla , Azhari Omer Abdelbagi

Abstract: Laboratory experiments were carried out to evaluate the efficacy of the fumigant action of garlic volatile oils on the control of Tribolium castaneum (adult) in small plastic cups (200 ml) and jute sacs (100 g) as well as to shed light on suitable fumigation period and oil concentrations. Fumigation was carried out for short exposure period (12- 48 hrs) as well as over medium (3-15 days) and longer exposure period (15-60 days). Recoveries were watched upto seven days. Garlic volatile oils were tested at concentrations ranging between 0.1- 20% V/V for the short and medium periods and 0.001 – 1% V/V for the longer periods. The results of the short exposure period (6-48 hrs) indicated that garlic volatile oil was very effective and caused significant death to the test insects (T. castaneum (adult)) in cups at all concentrations (after waiting for recoveries for seven days). Effect was dose dependant. Recovery cases noticed were negatively related to the dose. Garlic oil vapours penetrated through jute sacs and caused significant mortalaties to the test insects inside the sacs at all concentrations (0.1- 20% V/V) in medium exposure period (3-15 days) as compared to control. Effect was dosage related.The efficacy was tested at much lower concentration of garlic oil (0.001 – 1%) and over longer exposure period (15 – 60 days) in sacs. Results revealed that T. castaneum (adult) was sensitivite to garlic oil vapor at all concentrations. Effects were also dose related. The performance of garlic fumigation in cups is much similar to that in sacs. Recovery cases were few and negatively related to the dose.
