The efficacy and longevity of VectoBac 12 AS and VectoBacG (both based on Bacillus thuringiensis subsp. israelensis) for the control of mosquitoes in Turkey

Ankara ilinin Gölbaşı ilçesinde, alan şartlarında, B. thunngiensis (H-14)'in ticari preparatlarından VectoBac® 12 AS (aqueous suspension) and VectoBac® G (corn cob formulation) göl kenarı, su birikintisi ve bataklık habitatında Anopheles sacharovi. An. maculipennis, Culex pipiens ve Cx. theileri larvalarına karşı denendi. Orta Anadolu şartlarında, VectoBac® 12 AS'nin 1-1,25 l/hâ, VectoBac G'nin 7,5-10 kg/ha oranları ile, bütün sivrisinek larvaları için mükemmel bir başlangıç kontrolü (% 90-100) sağlandı. Uygulamaların tümünde, doz oranlarına bağlı olarak larva ölümlerinde artış belirlendi, fakat; uygulama sonrası 20. günde doz oranı ile kalıcı etkinlik arasında anlamlı bir ilişki belirlenemedi (P > 0,05).

Türkiye'de sivrisinek kontrolünde Bacillus thuringiensis subsp. israelensis'in VectoBac 12 AS ve VectoBac G preparatlarının etkinlik ve kalıcılığı

Under the field conditions of the Gölbaşı district of Ankara, commercial preparations of VectoBac® 12 AS (aqueous suspension) and VectoBac® G (corn cob formulation), both based on Bacillus thunngiensis subsp. israelensis (H-14), were tested against Anopheles sacharovf. An. maculipennis, Culex pipiens, and Cx. theileri larvae at the edge of a lake, a flood plain, and a swamp. Applying VectoBac® 12 AS at the rate of 1.0-1.25 I/ha and VectoBac® G at 7.5-10.0 kg/ha produced excellent initial control (90%- 100%) of all mosquito larvae under Central Anatolian conditions. An increase in larval mortality was detected in all treatments as dose rates increased, but there was no significant difference between dose rates and residual activity on post-treatment day 20 (P > 0.05).
