Gender pheromone-baited water otherwise funnel (delta) barriers imply the current presence of S

tangolias in the world and you will store of the drawing men adults. They’re regularly discover the early exposure off S. tangolias so you’re able to grab sufficient handle.

Classical biological manage. Classical biological manage would be an effective means in every the individuals regions where in fact the insect might have been unintentionally produced to save the newest insect population under the control tolerance (described in point cuatro.step 1.step one, P. operculella).

Overseeing having pheromone traps

Avoid infestation out of insect-free potato-growing zones. Infested seed facilitates the fresh new prompt spread of your insect which is a primary supply of first infestation within the potato sphere. Ergo, pest-100 % free seeds tubers must be planted.

Enough hilling. In the world, larvae must go into the soil to arrive brand new potato tubers. New infestation off potato tubers decreases towards depth within the floor in which it generate. Ergo potato tubers have to be shielded better that have surface throughout the whole cultivation period.

End inactive soil requirements. Dry-weather conditions prefer multiplication from S. tangolias in the arena because the number of egg applied reduces strongly having higher soil dampness; larvae block inside highly damp ground also. The new growing big date can be modified to avoid very long periods from dry-weather, particularly in the latest weeks before assemble. If you have small rain, sprinkler irrigation are often used to moisten the latest surface.

Quick and you will complete assemble. Large tuber destroy in the compile might have been appear to for the reason that defer harvests in conjunction with dry-weather issues that permit several years growing in the world. Throughout dry attacks, fast harvest is crucial to get rid of tuber infestation (the larvae change from the fresh new stems on tubers if the plant wilts). Early-maturing variety can subscribe to slow down the likelihood of infestation. Leftover tubers (voluntary plant life) are often infested from the S. tangolias, taking a way to obtain re-infestation and require become removed from the field.

Clean storage business. Plagued potato areas are a source of toxic contamination getting tubers stored immediately after accumulate and in surrounding sphere and places. Prior to potato tubers was kept, the businesses have to be cleared thoroughly. Egg, larvae, and you can pupae apparently included in fractures of wall space, the new crushed, or in bags or packages used for sites must be got rid of. Simply compliment tubers will likely be chose to have shop.

Physiological handle. From inside the Peru, a dirt components out-of Bacillus thuringiensis is utilized to safeguard tubers in shops up against S. tangolias. B. thuringiensis var. kurstaki is very effective against S. tangolias. New scratchy effect of different varieties of powders (kaolin, calcium supplements carbonate, or others), the foundation of your elements, plus kills young larvae because of the bodily protective ability off the latest dust. Potato tubers shall be managed (powdered) personally immediately following compile and you can listed in sites.

Attract-and-destroy can be applied in the a density of one drop (a hundred µl)/m dos of storage area to minimize a man population and which tuber infestation.

This can be an oil materials on the pest’s sexual pheromone and contact insecticide because ingredients, which are applied in the an occurrence out-of dos,five hundred droplets (a hundred µl)/ha around to reduce the male people and therefore leaf and you can tuber infestation
