Effect of Triflumuron and Diflubenzuron on Survivability and Developmental Period of Life Stages of Tribolium castaneum (Herbst) Under Laboratory Conditions
Journal Title: Current Investigations in Agriculture and Current Research - Year 2018, Vol 3, Issue 5
Abstract
The contact action of triflumuron (TFM) and diflubenzuron (DFB) on development and survivability of Tribolium castaneum (Herbst) were studied. The mean developmental period was recorded in different concentrations of both BPUs. Lower percentage of hatching was recorded on TFM compared to DFB and control. TFM was more effective than DFB on the survivability of different life stages. TFM at 0.05ppm provided the highest duration (49 days) of developmental period, and the lowest duration was 32.33 days (near to control) in DFB at 0.005ppm. Percent reduction of adult emergence was highest in 0.1TFM as 85.95 and at 0.05 DFB as 62. 50.The red flour beetle, Tribolium castaneum (Herbst) has had a long association with human’s stored food. It is a major pest in anthropogenic structures used for the processing and storage of grain-based products and a wide range of other commodities [1]. The tropical climate encourages rapid growth of this cosmopolitan species, and the population increases rapidly from a small residue. Due to the development of resistance against almost all synthetic insecticides it is very difficult to control T. castaneum with the traditionally used insecticides. Among the alternative reduced-risk insecticides, the benzoylphenyl urea’s (BPUs) proved themselves as potent candidate in controlling both susceptible and resistant strains of T. castaneum [2]. BPUs act as stomach poisons [3] at longer exposures to larval instars of the beetle.
