Abstract

In spring and summer time; the female of almond saw fly lay eggs in and on plant tissue, once the eggs hatch the young larvae start to feed on the almond leaves, causing defoliation of the trees depending of the population levels. In this study; evaluating the effects of three mustard oil and two tea tree oil formulations used against larval stages of the almond insect pest Cimbex quadrimaculata (Müller, 1766) (Hymenoptera: Cimbicidae). The five botanical formulations tested under laboratory conditions, using dipping method of 3 cm diameter almond leaves, which, were dipped five different dose and air dried before offered to the first larval stages, including negative control using only water. Feeding and mortality rates of 240 larvae in total were followed up until the end of the pupal period and recorded. It was determined that the increased dose of the formulation containing mustard oil + allylisothiocyanate monoethanolamine dissolved in non-ionic surfactants was more effective than other botanical formulations. The results of this study are important for almond organic pest management.
