| Abstract |
The effect of bio-control agents alone (Biofly, Beauveria bassiana and Egyptian nematode, Steinernema carpocapsae) or with medical additive (Docusate Sodium) comparing with Super Misrona oil were studied on the grape mealybug, Planococcus ficus (Signoret) and its parasitoides Leptomastix dactylopii Howard (Hymenoptera : Encyrtidae) and predator, Scymnus syriacus Kirsch (Coleoptera : Coccinellidae) before and after pruning. In the first season (2008), the treatments with different bio-control agents (Biofly and Egyptian nematode) alone gave moderate percent reduction on the population of adult females and nymphs of P. ficus when comparing with Super Misrona oil, which gave also moderate or highly percent reduction after 1st, 2nd and 3rd weeks before and after pruning. Also, these bio-control agent compounds gave also moderate toxic effect on its parasitoides L. dactylopii and the predator, S. syriacus before and after pruning when comparing with Super Misrona oil, which gave also moderate toxicity after the 1st, 2nd and 3rd weeks. The data in the second season (2009) gave similar results to those obtained in the first year (2008). When mixing Biofly and Egyptian nematode with Docusate Sodium gave highly percent reduction on the population of adult females and nymphs of P. ficus comparing with mixture of Super Misrona oil + Docusate Sodium also gave highly percent reduction after the 1st, 2nd and 3rd weeks before and after pruning. Also, these bio-control agent compounds + Docusate Sodium gave moderate or highly toxic effect on its parasitoides and the predator before and after pruning comparing with Super Misrona oil + Docusate Sodium, which gave highly toxicity after the 1st, 2nd and 3rd weeks. The data in the second season (2009) gave similar results to those obtained in the first year (2008). It can be concluded that mixing the bio-control agents and mineral oils with medical additive (Docusate Sodium) increasing the effectiveness against the mealybug and could be using in Integrated Pest Management Programs "IPM" on the grape mealybug, Planococcus ficus, which becoming very dangerous pest on grape vine plants, especially in organic farms that exporting fruits to Europe and America.
