Abstract

Field experiments were carried out at Sennourus, Fayoum Governorate, Egypt during the two successive seasons 2005 and 2006. Effective Microorganisms (EM), mixture of some chelated microelements (Zinc 12%, Copper (cupper) 12%, Manganese 12%, and Iron 12%) and a mixture of EM and microelements were used to study their effects on the populations of spider mite, aphids, thrips, whitefly, associated predators and resulting crop yield on cucumber plants. For the two seasons, mixture treatments induced maximum initial effect on spider mite, with mean numbers of 56.5 and 51.13 individuals /40 plants; followed by EM treatments (57.13 & 56.00 individuals /40 plants) and microelements treatments (96.25 & 63.38 individuals/40 plants) which were significantly lower than control (199.75 & 152.88 individuals/40 plants). The same trend occurred with aphids, thrips and whitefly. Obtained results showed no significant differences among predatory species in different treatments. The mixture treatments gave the highest yield (3.11 & 3.57 Kg/10 plants); followed by EM (3.00 & 3.15 Kg/10 plants) and microelements (2.92 & 3.14 Kg/10 plants) which all were significantly higher than the control (2.31 & 2 37 Kg/ 10 plants).
