Abstract
A study was conducted in 2007 and 2008 to investigate the effectiveness of grain amaranth (Amaranthus cruentus L.) planted at different times in an amaranth/cucumber intercrop to reduce the density of cucumber insect pests. Cucumber varieties, Marketmore and hybrid F1, were established from seed as a monocrop or intercropped with amaranth, and with amaranth established at two weeks before cucumber (2 WBC) on the same day as cucumber (SDC) or two weeks after cucumber (2 WAC). The population of cucumber beetles and fruit flies was lower with amaranth established 2 WBC and SDC than with 2 WAC. Populations of the insects were influenced by cropping system and time of introducing amaranth. Fruit damage by cucumber beetles and fruit flies was lower with 2 WBC and SDC than with 2 WAC. However, the damage was reduced in the intercrop compared with the monocropped cucumber. With SDC, the reduction was about 75 and 50% in 2007 and 2008, respectively. In intercrops and monocrops, cucumber fruit yield was influenced by the time of inter-cropping; in the mono- and inter-crop, the highest yield was with SDC. The highest land equivalent ratios for cucumber were 1.0 and 0.7 in 2007 and 2008, respectively, with SDC. Planting amaranth and cucumber on the same day (SDC) achieved effective control of cucumber insect pests.
