POPULATION DENSITY OF THE THREE DESTRUCTIVE INSECT PESTS INFESTING BROAD BEAN (Vicia faba L.) IN KAFR EL SHEIKH GOVERNORATE
A field experiment was carried out at Kafr El Sheikh Governorate during two successive seasons (2008-2009) and (2009/2010) to detect the population density of three destructive insect pests (Aphis craccivora, Empoasca decipience and Liriomyza trifolii) infesting broad bean plants; Vicia faba and cause economic losses in the crop, recording the population of each pest at the three levels of the plant and during the three developmental plant stages. The obtained results showed that the number of pests, that A. craccivora, E. decipiens and L. trifolii are considered three destructive pests which invade broadbean plant causing serious damage throughout the planting stages of broadbean.
IPM program of these insect pests should be included in view of the fact that the end site of the tested insects infestation in the plants in this location. A. craccivora was found with high density on upper level (recorded mean 26.66 individual/5 leaves in season 2008/2009 and 9.16 indiv./5 leaves in season 2009/2010) of Viciafaba through vegetative period of the plant ground season (gave 61.25 and 17.25 indiv./5 leaves) in 2008/2009 and 2009/2010 seasons, respectively. E. decipience attacking broadbean on upper and middle level of the plant during the fruiting stage (recorded for middle level 5.55 indiv./5 leaves and 4.72 indiv./5 leaves) in season 2008/2009 and 2009/2010, respectively and recorded 13.28 indiv./5 leaves and 19.85 indiv/5 leaves for fruiting stage in 2008/2009 and 2009/2010 seasons, respectively. L. trifolii caused highest damage in the plant leaves on basal level during the flowering and fruiting stages, (gave 62.83 indiv./5 leaves and 52.55 indiv./5 leaves in season 2008/2009 and 2009/2010, for lower level, flowering stage recorded 172.0 and 95.33 indiv/5 leaves in 2008/2009 and 2009/2010 seasons, respectively
This paper aims to guide in putting a correct and suitable IPM program, concerning the level of the plant on which each pest recorded its highest population beside the developmental stage found to receive the highest population and the timing of the infestation.
