Aphids are important pests of pepper and their abundance may be influenced by fertilizers. To address the influence of compost fertilizers on the morphology and biology of Myzus persicae Sulzer, an experiment was carried out in 2014/15 on pepper plants cultivated in a greenhouse. Five treatments using four types of composts (C1, C2, C3, and C4), a combination of vegetables scraps and equine, poultry, cattle and sheep manures and one control were used with six replications. The population of M. persicae on pepper for the five treatments was counted weekly and thirteen morphometric characters were studied. The results showed that aphid morphology and biology were affected by treatments. Highest population (4283 aphids/plant), higher mean relative growth rate (0.068) and lowest population doubling time (10.14 days) were registered with C4, whereas, minimum population (2019 aphids/plant), minimum mean relative growth rate (0.046) and higher population doubling time (15 days) were registered with C1. These results showed that C1 can reduce the damage caused by aphid on pepper and this knowledge might be useful in making a more informed compost fertilizer application choice.
