tangolias on earth and you may store because of the drawing men adults. They truly are regularly detect early visibility out-of S. tangolias in order to simply take enough handle.
Traditional physical handle. Traditional biological manage can be a means in every those people countries where pest might have been unintentionally lead to keep the newest insect society in manage threshold (described during the point 4.step one.1, P. operculella).
Prevent infestation off insect-free potato-growing zones. Infested vegetables encourages alleen dating site hoorndrager singles the fresh prompt pass on of your own insect that will be a prime way to obtain first infestation inside the potato industries. Thus, pest-100 % free vegetables tubers need to be planted.
Adequate hilling. On earth, larvae need to go into the floor to arrive the fresh potato tubers. The latest infestation out-of potato tubers minimizes to your breadth inside crushed in which they create. Hence potato tubers must be protected really with floor during the the whole cultivation period.
Avoid dead surface conditions. Dry-weather conditions favor multiplication from S. tangolias on the planet while the level of egg laid reduces highly with highest floor dampness; larvae block inside very wet ground also. The planting big date is going to be modified to quit long periods of dry-weather, particularly in the brand new days in advance of secure. When there is modest precipitation, sprinkler irrigation are often used to dampen the fresh new crushed.
Prompt and you can done accumulate. Highest tuber destroy during the amass might have been frequently for the reason that postponed harvests in conjunction with dry-weather conditions that enable numerous generations growing in the world. Throughout the dry symptoms, punctual harvest is a must to stop tuber infestation (the newest larvae go from the brand new stems into tubers when the plant wilts). Early-maturing variety can subscribe reduce the likelihood of infestation. Left tubers (voluntary flowers) are frequently infested by S. tangolias, getting a source of re also-infestation and require are taken out of the field.
Clean sites organization. Infested potato locations contain contaminants to own tubers held immediately following accumulate and in encompassing fields and you will locations. Ahead of potato tubers is stored, the stores should be cleared thoroughly. Eggs, larvae, and you can pupae apparently included in splits of your own wall space, the brand new soil, or perhaps in handbags otherwise packages employed for sites have to be got rid of. Just healthy tubers is going to be selected to own sites.
Physiological control. When you look at the Peru, a dust materials regarding Bacillus thuringiensis is used to safeguard tubers inside storage facing S. tangolias. B. thuringiensis var. kurstaki works well against S. tangolias. This new abrasive effect of different varieties of powders (kaolin, calcium carbonate, otherwise anybody else), the basis of one’s formulation, also eliminates young larvae as a result of the physical protective strength out-of new powder. Potato tubers are going to be handled (powdered) privately once collect and you will listed in stores.
Attract-and-destroy applies on a density of one get rid of (one hundred µl)/yards dos out of space for storing to attenuate the male populace and you will which tuber infestation.
