Abstract
Field experiment was carried out under rain-fed conditions during the 2013 and 2014 cropping seasons at the Teaching and Research Farm of the Department of Agricultural Technology, Adamawa State College of Agriculture, Ganye, solely to develop an integrated pest management for the control of groundnut Aphid (Aphis craccivora Koch) [Homoptera: Aphididae]. The experimental Design used was the Randomized Complete Block Design (RCBD). Parameters measured were, average number of leaves per plot at 6 weeks after sowing, number of branches at 3 weeks after sowing, number of branches at 6 weeks after sowing, number of pods per plot, weight of harvested seeds per plot. The result obtained shows that, there was significant difference among the treatments in all the parameters measured at 0.05 level of probability using the Least Significant Difference (LSD). According to the results recorded, the highest mean yield of groundnut was obtained on plots treated with the combination of chemical and physical control methods (1444g) followed by plots treated with physical, chemical and cultural control methods combined (1296g). The highest mean number of pods per plant was recorded in the combination of physical, chemical and cultural control methods (18.00) followed by chemical and physical control methods as combined (15.00). The work shows that, the cultivation of groundnut with the control of groundnut Aphid (Aphis craccivora Koch) using integrated pest control applied as recommended facilitates better growth and guarantees good crop yield. The use of physical, chemical and cultural control method is profitable in Ganye Area of Adamawa State and is therefore suggested for use to local farmers.

Abstract
Rice (Oryza sativa L.) is one of the most important food crops in the world. Purple rice, as a special rice with important nutritional and health functions, has important scientific significance and application value for genetic improvement of purple rice and breeding of new varieties through in-depth study on its agronomic and related quality traits and products processed, and analysis of its genetic basis. In this paper, the new progress of purple rice in agronomic traits, quality traits, environmental impacts on purple rice and genetic basis of purple rice seed coat in recent years were reviewed and analyzed, and the application prospects of purple rice processing products and purple gene in rice genetic improvement were also prospected. Thus, our results will provide important information and reference for breeding new purple rice varieties with good quality and high yield.
