ABSTRACT: Hot Pepper (Capsicum spp.) is an important spice and vegetable crop in Ethiopia. In nature, potyvirus is transmitted non persistently by at least five aphid species. Therefore, this study was conducted with the objective of identifying the effects of intercropping pepper on aphid population, yield and yield components of pepper. Field experiments were conducted in two localities; Mareko and Meskan of southern Ethiopia from April to October 2011. The experiments were conducted with RCBD design with four replication. Treatments were combination of pepper with maize, pepper with sweet potato, pepper with maize and sweet potato and sole pepper as a control. Aphids were collected by using yellow water traps two times a week. Data on yield and yield components were taken at harvest. Results of the experiment revealed that intercropping of pepper with maize significantly (p<0.001) reduced aphid populations. In addition, it significantly (p<0.01) increased marketable pod yield and reduced unmarketable yield. The largest numbers of aphids (ca. 25 aphids at each location were caught from control plots while only about 12 and 10 of pepper intercropped with maize and sweet potato in Mareko and Meskan, respectively. Intercropping pepper with maize increased the marketable and total yield of pepper by 39% and 33% at Mareko 33% and 23% at Meskan. Intercropping of pepper with sweet potato neither increases nor was decrease the yield of pepper and LER value one. On the other hand, intercropping of pepper with maize and sweet potato reduced the pepper yield by 13% and 14% as compared to the control at Mareko and Meskan, respectively. Therefore, intercropping of pepper with maize can serve as reduction of aphid vectors infestation and improves pepper yield.
