Abstract
For effective vector control it is essential to formulate new preparations having multiple action against the vector pest. Developing combined formulation of biopesticide and chemical pesticide is one of the novel concept to fight against the vectors with new weapons; however, compatibility of biopesticide i.e . Bacillus thuringiensis (Bt) and chemical pesticide is a real hurdle. In this investigation, local isolate Bacillus thuringiensis SV2 (BtSV2) was tested for its compatibility with various available mosquito larvicides. Temephos was most compatible with BtSV2 than with other tested pesticides. These two compatible agents were tested for larvicidal potential. Our study revealed that the synergistic effect of both agents reduces LC50 value by 30.68 and 22.36% against the Ae . aegypti and An . stephensi , respectively. The larvicidal potential increased when compared to individual pesticides. It was also observed a biochemical change in larvae after the TBT (Temephos + Bacillus thuringiensis) combination treatment; it involves decreased level of alpha esterase, acetylcholine esterase and protein while level of beta esterase and acid phosphatase was unchanged and alkaline phosphatase activity was increased. Increased potential of combined formulation may be due to altered physiological condition.
期刊介绍：
The Journal of Entomological and Acarological Research (JEAR), formerly the Bollettino di Zoologia Agraria e di Bachicoltura of the Institute of Entomology of the Università degli Studi, Milano, was founded in 1928 by Remo Grandori. Thereafter, Minos Martelli and Luciano Süss hold the direction of the Journal until December 2011. In January 2012 the Editor decided for the new open-access on-line version of JEAR. The Journal publishes original research papers concerning Arthopods, but reviews, editorials, technical reports, brief notes, conference proceeding, letters to the Editor, book reviews are also welcome. JEAR has four main areas of interest: -Entomology (systematics; morphology; biology; biotechnology; agriculture, ornamental and forest entomology; applied entomology; integrated pest management; biological control; apiculture and apidology; medical, urban and veterinary entomology; etc.) -Stored product pests (biology; integrated pest management; etc.) -Insect Ecology (behaviour; biodiversity; taxonomy; plant insect interaction and ecosystems; biological control; alien species; etc.) -Acarology (systematics; morphology; biology; parasitology; control; etc.) The publication of manuscripts is subject to the approval of the Section Editor who has knowledge of the field discussed in the manuscript in accordance with the principles of Peer Review; referees will be selected from the Editorial Board or among qualified scientists of the international scientific community. Articles must be written in English and must adhere to the guidelines and details contained in the Instructions to Authors.
