Investigation of Pirimiphos-methyl Resistance Status of Culex pipiens (Diptera: Culicidae) Populations in Northern Tunisia

چکیده
This article reports Pirimiphos-methyl resistance status of Culex pipiens populations harvested in four breeding sites in Northern Tunisia. Our results showed the resistance of all samples to Pirimiphos-methyl. The RR50 ranged from 3.3 1 to 62.1. The sample collected from Tazarka had the highest resistance among all studied populations. This status could be explained by its frequency of mortality caused by propoxur (0%) and also by its frequency of detected esterases (85%). Authors confirmed the implications of insensitive acetylcholinesterase and esterases enzymes in the resistance of Culex pipiens populations to Pirimiphos-methyl. It is the first investigation of Pirimiphos-methyl resistance status of Culex pipiens populations from Tunisia and it is very important for the implementation and development of vector control strategies.

Pirimiphos-methyl Resistance of Culex pipiens Populations (Diptera: Culicidae) in Central Tunisia: Status and Mechanisms Involved
In Tunisia, Culex pipiens plays a role in the high annoyance experienced by most urban cities, suburban and rural areas. Resistance to Pirimiphos-methyl was analyzed in five populations of Culex pipiens collected in central Tunisia. Bioassays were performed over different larvae samples. All samples were resistant to Pirimiphos-methyl. The study of the mechanisms involved in this resistance sho...
متن کاملPirimiphos-Methyl Resistance Status of Field Populations of Culex pipiens (Diptera: Culicidae) From Grand Tunis Area, Northeast Tunisian
Mosquito species are responsible for the transmission of many parasitic diseases and their control leads to the phenomenon of resistance to insecticides. Five Culex pipiens samples were collected from various localities of Grand Tunis area, Northeast Tunisia, between June 2003 and November 2005. All the studied samples were resistant to pirimiphos methyl (organophosphorus insecticide). Our resu...

متن کاملDevelopment of Resistance to Chlorpyrifos in Culex pipiens (Diptera: Culicidae) Population under Temephos Selection Pressures
Development of resistance to chlorpyrifos in Culex pipiens population from Tunisia under temephos selection pressures was investigated. The objective of this study was to follow the evolution of resistance responses in Culex pipiens larvae under laboratory conditions. The selection to temephos caused a significant increase of resistance to chlorpyrifos levels. Indeed, the LD50 resistance rate i...
