Tuta absoluta is an endemic pest in South America where it causes a significant crop loss in tomato growing areas. A survey was carried out in August 2015 whereby a total of 100 tomato growers were interviewed randomly to assess their knowledge, perceptions and practices regarding Tuta absoluta. Semi-structured questionnaire open and close ended was used to assess knowledge perceptions and practices about the invasive insect pest. The results revealed that (80%) of the farmers were aware of the Tuta absoluta as a major problem in tomato growing areas. Furthermore, of the total respondents showed (90%) of the growers demonstrated poor knowledge on the taxonomy of the pest and its economic impact in tomato production. A total of (70%) of the growers completed standard seven, own cellphone for exchange various informat...

This study was conducted in smallholder bean fields in three elevation zones to assess the importance of field margin vegetation to natural enemy populations and movement to the bean crop for biological pest control. The pests and natural enemies were assessed using different coloured water pan traps (to ensure the capture of insects with different colour preferences) and the interactions of the two arthropod groups with the margin vegetation and their movement to the bean crop were monitored using fluorescent dye. Sentinel plants were used to assess predation and parasitism levels. A total of 5003 natural enemies were captured, more in the field margin than within the bean field for low and mid elevation zones, while in the high elevation zone, they were more abunda...
