Sažetak
An insecticidal efficacy of new developed two grain protectant formulations was assessed against lesser grain borer Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae) on wheat and corn after 6 months period of storage (CSF Project IP-11-2013-5570). Tested formulations, marked as F1H and F2H, based on inert dust, laurel leaves, lavender essential oil, corn oil, silica gel (both F1H and F2H) and pyrethrin (only F2H) were tested at six doses (from 100 ppm to 600 ppm) depending on formulation and type of cereals. The appropriate weights of each formulation, separately were added to a plastic containers containing 10 kg of wheat and corn, separately. The initial population of 200 adults of R. dominica were added into each container and left under natural environmental conditions up to 6 months. A standard USA diatomaceous earth (DE) Celatom® Mn 51 was used for the comparison of the results, as long with the untreated control. After six months, both formulations showed higher insecticidal effect than DE Mn 51 in corn and in wheat. Further, initial population of R. dominica, prior introduced in wheat, was suppressed almost completely, with only 0.7%-5.3% live adults found, depending on formulations and dose. The order of efficacy was F1H>F2H>DE Mn 51. Similar suppression of the initial population was recorded in corn, where F2H was slightly more effective than F1H with 2.0%-10.6% and 4.1%-9.5% live adults found, respectively. At the same time, in the treatments with DE Mn 51 there were 4.7%-74.7% and 33.4%-56.1% live adults in wheat and corn, respectively.
