tangolias in the world and you will shop by attracting men people. They’re regularly place the early exposure of S. tangolias in order to capture enough handle.

Ancient physical handle. Ancient physical control is a great strategy in most the individuals regions in which the insect has been unintentionally delivered to store the new pest people under the handle threshold (revealed for the point 4.step one.step one, P. operculella).

Overseeing that have pheromone traps

Stop infestation of pest-totally free potato-increasing areas. Plagued seeds encourages the newest prompt bequeath of one’s insect and is a prime supply of http://www.datingmentor.org/escort/corona/ 1st infestation for the potato fields. Hence, pest-totally free vegetables tubers have to be planted.

Enough hilling. In this field, larvae need go into the surface to arrive brand new potato tubers. The fresh new infestation of potato tubers reduces on the breadth from inside the ground where it establish. For this reason potato tubers should be secured better with floor through the the whole cultivation months.

Stop dry floor criteria. Dry-weather conditions favor multiplication away from S. tangolias on the planet just like the amount of eggs laid reduces strongly having large soil moisture; larvae block in highly wet floor too. New sowing time are adjusted to get rid of long stretches from dry-weather, especially in brand new months before amass. When there is modest precipitation, sprinkler irrigation can be used to dampen the newest surface.

Timely and complete assemble. Highest tuber ruin in the harvest might have been frequently considering put-off harvests in combination with dry-weather issues that permit numerous years growing in the arena. During the dead episodes, quick gather is vital to stop tuber infestation (the larvae change from the brand new stems to your tubers if plant wilts). Early-maturing types normally contribute to slow down the risk of infestation. Remaining tubers (voluntary plants) are often infested by the S. tangolias, bringing a way to obtain re also-infestation and want as taken off industry.

Brush shop business. Plagued potato places include pollution to possess tubers stored just after amass as well as in encompassing areas and you can areas. Just before potato tubers is kept, the businesses have to be cleared thoroughly. Egg, larvae, and you may pupae frequently included in cracks of the walls, this new surface, or in bags or packets used for sites need to be removed. Only match tubers is going to be picked having shops.

Physiological control. When you look at the Peru, a soil formulation away from Bacillus thuringiensis is used to safeguard tubers within the sites up against S. tangolias. B. thuringiensis var. kurstaki is very effective up against S. tangolias. The rough effect of different varieties of powders (kaolin, calcium carbonate, otherwise anybody else), which is the base of the ingredients, and kills more youthful larvae as a result of the physical protective strength of the new powder. Potato tubers is addressed (powdered) in person after amass and you will placed in shop.

Attract-and-kill enforce on a density of a single miss (100 µl)/m 2 out-of space for storage to minimize the male people and hence tuber infestation.

This really is an oil elements to the pest’s sexual pheromone and you can get in touch with insecticide as substances, being applied from the a density out-of 2,500 droplets (a hundred µl)/ha in the arena to reduce the male population so because of this leaf and you may tuber infestation
