The survey, achieved in the west of Burkina in laboratory conditions (average temperature of 28,21°C and average relative humidity of 73%), aimed to value some biologic parameters of Antigastra catalaunalis. Thus, twenty couples of the pyrale have been followed for the survey of the punter and sixty larvas for the survey of the features and the lengths of the different larval stages. Besides, the bursting rate of the eggs, mortality rate of the larvas, chrysalisation rate of the larvas and emergence rate of the adults have been valued. The results reveals that the females of A. catalaunalis lay 299 eggs on average during 5,5 days with a rate of bursting of 67,06%. Besides, the pyrale passes by five larval stages and has an average development cycle of 21,95 days for the males and 24,45 days for the females. It is necessary to note that the sex-ratio is 1: 1,58. the L1 larvas presented the strongest mortality (23,33%). otherwise, the chrysalisation rate of the larvas was 90,37% and the emergence rate of the adults was 81,57%. At last, it would be interesting to quantify the impact of A. catalaunalis on the different varieties of sesame popularized in Burkina.

In Burkina Faso, corpses discoveries are common especially in Ouagadougou and Bobo-Dioulasso respectively the political and the economical capitals. These two towns are the most populous cities of this country. With a low rate of elucidation of criminal cases, legal entomology remains an asset for investigators if it is known. The purpose of the present study was to take stock of the knowledge of legal entomology among the main actors involved in the criminal investigations in Burkina Faso. To conduct this study, 192 actors in the judicial chain have been concerned. Among these actors, there was 107 policemen (55. 7%), 40 gendarmes (20.8%), 33 magistrates (17.2%) and 12 doctors (6.3%). After explaining the details of the survey, a series of questions was submitted to them. Of those responding, 86% recognized the importance of legal entomology and its introduction in their basic training.

Many human activities affect arthropod diversity and may threaten environmental health. Some insects may act as biological indicators based on their presence or absence in an ecosystem. The present study was conducted from 2006 to 2009 to evaluate changes in the diversity and abundance of ground Carabids following restoration activities conducted in three lowlands ecosystems that had previously experienced high levels of human pressure in Burkina Faso. Three micro-catchments were identified in the regions of Soum, Sanmatenga, and Kompienga, using a hydrographic chart of Burkina Faso. The diversity and abundance of carabids collected in pitfall traps at the beginning and end of the rainy season were compared using 2006 as a sampling reference year with restoration activities (abandonment of farming, forestation and scarification) occurring in 2007. Post-treatment surveys were conducted in the same seasons of 2008 and 2009. Forty-nine species of Carabids have been identified based on monitoring of 1800 pitfall traps. The number of species generally increased in 2008 and 2009, from 9 to 41 species in the three micro-catchments. Species richness and insect abundance definitely increased where human pressure decreased and restoration measures were successfully conducted. However, Carabid diversity increased only in Soum micro-catchment; this site seemed to be more affected by restoration. Carabids are likely to be good indicator species; reports can be prepared relatively quickly. The results are discussed in relation to the goal of developing ecologically sound tools based on bio-indicator insects that can be used for environmental management.
