Summer squash (Cucurbita pepo) commonly known as Zucchini, one of the most economically important vegetable crops grown in many tropical and subtropical regions of the world (Paris H., 1996). It is a quick-growing early yielding cucurbit cultivated throughout Nepal–recommended to both the Terai and the hilly region of Nepal. It is popular and grown worldwide particularly for oil and medical purposes as it possesses several pharmacological effects as antidiabetic, antihypertensive, antitumor, antimutagenic, immunomodulating, antibacterial, antihypercholesterolemic, intestinal antiparasitic, antalgic, and antiinflammation effects (Bannayan, Rezaei, & Alizadeh, 2011; Caili, Huan, & Li, 2006). Although it offers great importance, the production of summer squash is particularly hampered by the incidence of various insect pests (Sarwar, 2014). This might be one of the reasons for the lower yield ie 15.59 Mt ha-1 of summer squash compared to its attainable yield ie 40 Mt ha-1 (MoAD, 2017/18) as farmers are discouraged to cultivate this crop.
