Abstract

In field experiment at Giza Governorate, Egypt during 2012 and
2013 seasons, aphids; Aphis gossypii Glover and its predator; Coccinella
undecimpunctata L. on cucumber plantations were affected by temperature
and relative humidity. The temperature had a significant positive
correlation with population densities of aphids and the predator (r = 0.78,
0.79, 0.66 and 0.73) in both sucssive seasons; respactively, meanwhile
rlative humidity correlated significantely negative with the population
dinisty of Aphids, (r = -0.75 and -0.71). Coccinella undecimpunctata
however was non-significant correlated with relative humidy , (r = -0.59
and -0.51) respectively. Statistical analysis also showed a strong positive
significant correlation between aphids and the predator (r= 0.90 and 0.91).
Therefore the studied abiotic factors affect independently the activities of
both the pest and predator. A. gossipii was affected positively by
temperature and negatively by relative humidity while, C. undecimpunctata
was affected positively by temperature and aphid population. Relative
humidity had no significant effect on the predator.
