Gender pheromone-baited h2o or harness (delta) traps mean the presence of S

tangolias around and you will shop of the attracting men people. They truly are always find the early presence of S. tangolias so you’re able to grab adequate manage.

Ancient physical control. Ancient physiological manage will likely be a beneficial strategy in every people places where in fact the pest has been accidentally delivered to save new pest society within the manage threshold (demonstrated during the part 4.step 1.1, P. operculella).

Overseeing having pheromone barriers

Prevent infestation away from insect-totally free potato-increasing areas. Infested vegetables encourages the brand new quick pass on of one’s insect in fact it is a prime source of first infestation when you look at the potato industries. Thus, pest-totally free seeds tubers must be rooted.

Enough hilling. In this field, larvae need enter the surface to-arrive the brand new potato tubers. New infestation out-of potato tubers reduces to the breadth from inside the ground where they generate. Hence potato tubers must be secured better with surface during the whole cultivation months.

Prevent deceased ground criteria. Dry-weather requirements like multiplication off S. tangolias on the planet as number of eggs placed decreases strongly which have higher floor dampness; larvae block within the highly damp ground too. The fresh growing time might be adjusted to prevent extended periods out-of dry-weather, particularly in the latest months ahead of compile. If there’s more compact precipitation, sprinkler irrigation can be used to dampen the brand new crushed.

Timely and you can over gather. High tuber wreck in the compile could have been frequently because of put off harvests in combination with dry weather conditions that enable multiple years to cultivate in this field. During the inactive symptoms, fast secure is extremely important to avoid tuber infestation (brand new larvae go from brand new stems on the tubers in the event that bush wilts). Early-maturing kinds can be join reduce the risk of infestation. Leftover tubers (voluntary plant life) are often plagued of the S. tangolias, delivering a supply of re-infestation and want to be removed from industry.

Brush stores organization. Infested potato areas contain contamination to possess tubers stored once accumulate plus surrounding areas and you can locations. Just before potato tubers are kept, the businesses need to be removed carefully. Eggs, larvae, and you may pupae frequently found in cracks of one’s walls, the floor, or even in handbags or boxes used in shop need to be removed. Only match tubers would be chose to possess sites.

Physical control. Inside the Peru, a click here to read soil ingredients regarding Bacillus thuringiensis is used to safeguard tubers into the shop against S. tangolias. B. thuringiensis var. kurstaki works well facing S. tangolias. The fresh rough effectation of different kinds of powders (kaolin, calcium carbonate, otherwise someone else), the foundation of the elements, in addition to eliminates young larvae as a result of the real defensive potential of the dust. Potato tubers shall be handled (powdered) truly shortly after collect and you can placed in shop.

Attract-and-kill is applicable on a thickness of a single drop (100 µl)/yards 2 of storage space to attenuate the male people and hence tuber infestation.

That is an oil components on the pest’s sexual pheromone and you will get in touch with insecticide because ingredients, which happen to be used from the a density of dos,500 droplets (100 µl)/ha around to attenuate a man populace so because of this leaf and you can tuber infestation
