Field evaluation of synthetic sex pheromone traps for the cocoa mirid Sahlbergella singularis (Hemiptera: Miridae).
BACKGROUND Field trapping experiments were conducted to evaluate the attractiveness of five different pheromone blends as well as the impact of trap design on attractiveness towards cocoa mirids, Sahlbergella singularis Hagl. and Distantiella theobroma (Dist.), in Cameroon. RESULTS A total of 361 adults of S. singularis (359 males and two females) were caught. The highest numbers of mirids we...
متن کاملIsolation and Characterization of Twelve Polymorphic Microsatellite Loci for the Cocoa Mirid Bug Sahlbergella Singularis
Mirids are the primary pests affecting cocoa production in Africa, but no genetic studies have been conducted on these insects. Here we report the isolation and characterization of 12 polymorphic microsatellite loci for Sahlbergella singularis. A microsatellite-enriched genomic DNA library was developed and screened to identify marker loci. Twelve polymorphic loci were identified by screening 2...
متن کاملAntixenosis as a mechanism of cocoa resistance to the cocoa mirid, Sahlbergella singularis (Hemiptera: Miridae) [Antixénose comme une mécanisme de résistance du cacaoyer au miride, Sahlbergella singularis (Hemiptera: Miridae)]
Objectives: The objectives of this study were to confirm the existence and heritability of mirid resistance in selected promising cocoa genotypes and to determine whether antixenosis is involved in the mechanism of resistance. Methodology and results: Ten cocoa hybrids obtained from crosses between clones identified as susceptible or promising for resistance to the cocoa mirid, Sahlbergella sin...
متن کاملLife Table Parameters of Three Mirid Bug (Adelphocoris) Species (Hemiptera: Miridae) under Contrasted Relative Humidity Regimes
The genus Adelphocoris (Hemiptera: Miridae) is a group of important insect pests of Bt cotton in China. The three dominant species are A. lineolatus, A. suturalis, and A. fasciaticollis, and these species have different population dynamics. The causal factors for the differences in population dynamics have not been determined; one hypothesis is that humidity may be important for the growth of A...
متن کاملEvaluation of Field Damage and Chemical Control of Outbreak of Sahlbergella singularis Haglund in a Cocoa Plantation in Ibadan, Nigeria
Field evaluation of damage caused by the brown cocoa mirid, Sahlbergella singularis was based on three parameters, namely, lesions on pods, cankers on trunks and dieback of twigs. Damage assessment based on scoring exceeded 75% for damage to the trunks and fan branches while damage to the pods was more than 50% by the second cocoa season. Laboratory evaluation of endosulphan 35 EC applied at 0....
