VARIETAL PERFORMANCE OF SAPOTA AGAINST MAJOR INSECT PESTS UNDER HIGH DENSITY PLANTATION
Research Type
Departmental Research
Experiment Background
Sapota (Manilkara achras (Mill) Fosberg) commonly known as “Chiku” belongs to family sapotaceae. Sapota tree is attacked by about 23 insect pests in Gujarat, which affect the productivity quantitatively or qualitatively. Among the prescribed pests, bud borer, Anarsia achrasella Bradley and chiku moth/leaf webber, Nephopteryx eugraphella (Ragonot) are major pests of sapota causing very serious damage to bud, flower and leaves also.
Among different foliage insect pests, midrib folder (leaf folder), Banisia myrsusales elearalis (Walker) is a regular and major pest of sapota particularly in newly planted orchards.
Seed borer, Trymalitis margarias Meyrick has appeared as emerging pest and causing very serious damage during fruit harvesting period.
Fruit fly, Bactrocera spp. is a vital insect pest in sapota crop from consumption and export point of fruit quality.
Due to the infestation of fruit infesting pests, quality of the fruit deteriorates and hence the selling prices goes down in wholesale and retail market as well as farmers also lose their goodwill in the market.
Now a days, promotion of high density planting is on way to explore among farmers. Therefore, it is need to check the status of major insect pests of sapota in high density plantation.
