Mating disruption(MD)is an effective environmentally-friendly control method against the striped rice stem borer(RSB),Chilo suppressalis(Lepidoptera:Crambidae).In this study,the current MD dispensers release the pheromone exponentially,with higher initial release rates that decrease throughout the *** adjust the timing of dispensers'deployment and evaluate the importance of controlling the early first or the second male flight,field trials were carried out to test the efficacy of two strategies:the early dispenser deployment prior to the first male flight(May)and the late deployment prior to the second flight(June).The early dispenser deployment was more effective in reducing plant damage inflicted by RSB when assessed at ***,neither of these strategies was able to inhibit the male catches of the third flight due to the dispensers5 *** to the airborne pheromone concentrations obtained,around 1.60 ng/m3 were capable to inhib社*** male flight effectively.

A review was carried out in Medline,LILACS and the Cochrane *** database search strategy included the following terms: "hydatid cyst","liver","management","meta-analysis" and "randomized controlled trial".No language limits were used in the literature *** latest electronic search date was the 7th of January *** and exclusion criteria: all relevant studies on the assessment of therapeutic methods for hydatid cysts of the liver were considered for *** from editorials,letters to publishers,low quality review articles and studies done on animals were excluded from ***,well-structured abstracts from relevant articles were selected and accepted for *** forms were designed for data extraction; two investigators entered the data on patient demographics,methodology,recurrence of HC,mean cyst size and number of cysts per *** hundred and fourteen articles were identified using the previously described search *** applying the inclusion and exclusion criteria detailed above,57 articles were selected for final analysis: one meta-analysis,9 randomized clinical trials,5 non-randomized comparative prospective studies,7 non-comparative prospective studies,and 34 retrospective studies(12 comparative and 22 noncomparative).Our results indicate that antihelminthic treatment alone is not the ideal treatment for liver hydatid *** studies in the literature support the effectiveness of radical treatment compared with conservative *** surgery with omentoplasty is effective in preventing postoperative complications.A laparoscopic approach is safe in some *** drainage with albendazole therapy is a safe and effective alternative treatment for hydatid cysts of the *** surgery with preand post-operative administration of albendazole is the best treatment option for liver hydatid cysts due to low recurrence and complication rates.
