Control of the complex of Heliothis in commercial plantings of cotton by means of the use of maize as a trap crop



Control of the complex of Heliothis in commercial plantings of cotton by means of the use of maize as a trap crop



Agronomia Tropical 1984 recd 1986; 32(1/6): 187-194



Field tests were carried out in commercial cotton fields in Venezuela in 1978-79 to evaluate the use of maize as a trap crop to control the noctuid Heliothis zea. Maize was sown 10, 25 or 40 days after the cotton was planted and was placed between every 24 cotton rows. In 1977-78, only 0.1% of the reproductive parts of 20 988 cotton plants examined were found to be damaged by the bollworm, as compared with 28.2% damage on the 1580 ears of maize examined.
