Abstract

A study was carried out to estimate population density of
cowpea aphid, Aphis craccivrora Koch and its predators associated
bean plants.
Population fluctuation of A. craccivrora and its three predators,
i.e., Coccinella undecimpunctata L., Chrysoperla carnea Steph and
Syrphus corollae F. were studied and released on bean which
surrounded by cabbage plants as compared with other fields unsurrounded at Sennoris district, Fayoum Governorate during summer
plantation 2011/2012.
The obtained results showed that the population density of three
predators at bean fields surrounding by cabbage more than twice
(<100%) neighboring ones by mean counts by mean counts were
101.8 and 42.3 predators /20 plants, respectively. Statistical analysis
showed highly significant differences between the tested field and the
neighboring ones.
The obtained results indicated that there was reduction in aphid
population ranged between 9.53 to 75.20 by mean 47.79% concerning
the number of the predators. Results also revealed that there were
highly significant increase in bean green yield over neighboring
check field (control) of about 70.0 % in bean plots inter-cropped with
cabbage plants .
