Market More and Pointset cucumber varieties were used as treatments. Data were collected at three different phonological growth stages with damaged they caused. Data collections commenced at 2 weeks after planting (WAP) and were on weekly basis for six weeks. Four major insect pests observed were Phyllotreta cruciferae Fabricius, Diabrotical undecimpunctata Howardi Barber, Epilachna vigintiopunctata Fabricius and Monolepta spp Coquilletta on the two varieties observed. Except Epilachna, which belong to the family Coccinellidae others are from the family Chrymesolidae. Also, all the insects pest recorded the highest population at seedling and the population reduces at flowering to fruiting stage while Epilachna recorded the highest population at fruiting stage. The same trend was also observed for distribution across the age of the plant.

Highlights

Vegetables are important in the human diet for the provision of carbohydrates, proteins, vitamins and trace elements they contain (Bakre et al, 2004).In addition to dietary benefits, thereare important supplementary sources of food and nutrition and serve as one of the major sources of income for small scale farmers to highly commercial farmers. (Selleck and Opena, 1985)
It was observed from the field that four major insect pests of cucumber were common in the area of study
P. cruciferae was considered as the most destructive among the insect pests observed because it had direct effect on the crop by feeding on the leaves

Introduction

(Selleck and Opena, 1985). Vegetables are important in the human diet for the provision of carbohydrates, proteins, vitamins and trace elements they contain (Bakre et al, 2004).In addition to dietary benefits, thereare important supplementary sources of food and nutrition and serve as one of the major sources of income for small scale farmers to highly commercial farmers. Vegetables constitute the fourth largest group of commodities produced in Africa (FAO, 2000). Cucumber is a fruit vegetable which belongs to the Cucurbitaceae family that has been cultivated by man for over 3,000 years (Adetula and Denton, 2003; Okonmah, 2011). Cucumber (Cucumis sativus L.) and water melon (Citrullus lanatus L.) was ranked best among the 20 most important vegetable crops worldwide (FAOSTAT, 2008). Cucumber is resident to Africa and Asia continent (Sebastian et al, 2010). The crop is cultivated in most parts of northern and eastern Nigeria by peasant farmers (Ekwu, 2007)
