Sex pheromone-baited liquid otherwise funnel (delta) barriers suggest the presence of S

tangolias in the field and you can shop of the drawing men grownups. They truly are accustomed find the early presence from S. tangolias so you can simply take enough manage.

Classical physiological manage. Ancient physical control are going to be a great method in all those nations where the pest might have been accidentally lead to save brand new pest inhabitants underneath the manage endurance (revealed in section 4.1.step 1, P. operculella).

Monitoring which have pheromone traps

Avoid infestation away from pest-free potato-increasing areas. Plagued seeds encourages the newest punctual bequeath of pest which will be a primary source of initial infestation inside the potato industries. Hence, pest-totally free seed products tubers must be rooted.

Enough hilling. In this field, larvae need to go into the soil to arrive brand new potato tubers. The infestation off potato tubers minimizes to the breadth within the crushed in which it create. Hence potato tubers need to be secure well having soil throughout the the entire cultivation several months.

Prevent dead crushed requirements. Dry weather standards prefer multiplication out of S. tangolias on earth because the level of eggs placed reduces highly which have high surface water; larvae block in the highly damp surface as well. The newest sowing date should be adjusted to quit long periods regarding dry-weather, especially in brand new months before amass. If you have more compact precipitation, sprinkler irrigation can be used to dampen the new surface.

Timely and complete assemble. Large tuber wreck from the compile might have been apparently caused by postponed harvests in combination with dry-weather conditions that permit multiple generations to cultivate on the planet. While in the lifeless periods, timely secure is a must to avoid tuber infestation (the newest larvae move from the stems for the tubers when the plant wilts). Early-maturing species is contribute to reduce the danger of infestation. Remaining tubers (volunteer flowers) are frequently infested by S. tangolias, getting a way to obtain lso are-infestation and want to get taken from industry.

Clean stores facilities. Infested potato places are a source of contaminants having tubers held once gather and also in close sphere and you can locations. Before potato tubers are held, the businesses should be eliminated carefully. Eggs, larvae, and you can pupae frequently used in breaks of your walls, brand new soil, or in handbags or packages utilized for sites have to be got rid of. Only suit tubers would be picked to own shop.

Biological manage. Inside the Peru, a dust materials off Bacillus thuringiensis is employed to protect tubers within the shops against S. tangolias. B. thuringiensis var. kurstaki is effective against S. tangolias. Brand new rough effect of different varieties of powders (kaolin, calcium supplements carbonate, otherwise anybody else), the base of your elements, in addition to kills younger larvae because of the actual defensive potential from the dust. Potato tubers should be managed (powdered) individually immediately after assemble and you will placed in stores.

Attract-and-eliminate applies within a density of a single shed (a hundred µl)/yards 2 from space for storage to attenuate a man population and you can and therefore tuber infestation.

This can be an oil materials toward pest’s sexual pheromone and get in touch with insecticide as substances, which are applied on an occurrence of 2,five hundred droplets (one hundred µl)/ha in the arena to attenuate the male inhabitants and hence leaf and you will tuber infestation
