Abstract
Cowpea [Vigna unguiculata (L.) Walp] is one of the most important legume crops in several parts of the world. Under field conditions these crops are infested with many insect pests during the different stages of plant growth. The shedder bug, Creontiades pallidus (Ramb); the long-tailed blue, Lampides boeticus L. and the cowpea seed beetle, Callosobruchus maculatus (Fabricius) are serious pests in most cowpea growing areas worldwide during flowering and fruiting stages.
Therefore, the present investigation deals with some ecological and biological aspects of previously mentioned pests in the field (at the Experimental Farm of Faculty of Agriculture, Mansoura University, Mansoura,) and laboratory conditions, during 2005 and 2006 seasons, which serve in achieving of some knowledge about the effective control of these pests.
The obtained results could be summarized as follow :
I. FIELD STUDIES :
1. Seasonal abundance of flower and pod insect pests of cowpea :
1.1. The shedder bug, Creontiades pallidus (Rambur) :
1) The mired species; C. pallidus had two distinct peaks of seasonal abundance in the first and second seasons. These peaks were recorded at the 16th of July & 4th of September (in the first season) and at the 30th of July & 11th of September (in the second season).
2) Statistical analysis indicated that C. pallidus population showed highly significant (r = 0.63**) and significantly (r = 0.48*) positive responses to the increase of temperature and relative humidity in the first season. In the second season, these responses were insignificantly positive towards mean temperature and relative humidity, however r-values were 0.16 and 0.44. The common effect of mean temperature and relative humidity C. pallidus population represented by 40.2 and 20.4% of the total factors affecting C. pallidus population during the first and second seasons.
