Fall armyworm and neotropical cornstalk borer on sorghum and maize intercropped with legumes in Honduras
The effects of intercropped legumes on densities of Spodoptera frugiperda (FAW) and Diatraea lineolata (NCSB) on sorghum (Sorghum bicolor) and maize (Zea mays) were studied in central Honduras in 1986 and 1987. Sorghum and maize intercropped were compared with intercropped sorghum-maize-pigeonpea in 1986 at Rapaco, El Paraiso, and with sorghum-maize-cowpea in 1987 at Rapaco and El Zamorano, Francisco Morazan in 1987. Infestations of FAW on sorghum and maize were similar for plots with or without pigeonpea in 1986. In 1987 sorghum and maize with cowpea had lower infestations of FAW than the intercropped system without cowpea at both locations. Infestations of NCSB were not affected by intercropping pigeonpea or cowpea with sorghum and maize. Numbers of adults and eggs of the predaceous earwig Doru taeniata were similar in plots with or without pigeonpea in 1986, but they were higher in plots with cowpea in 1987. Parasitoids were not influenced by cropping system.
