Studies with PBW-Rope dispenser form of gossyplure 78g a.i/ha in cotton ecosystem revealed that population of Menochilus sp, and spiders (Thomicidae) was more in PBW-Rope dispenser treated plots when used alone. When alternated with either fenvalerate or monocrotophos on the basis of ETL recorded more of Menochilus sp. than spiders. However, application of monocrotophos after the PBW-Rope dispenser was less toxic to both coccinellids and spiders. Fenvalerate spray once in 15 days reduced the coccinellids and spiders and when sprayed on the basis of ETL, was more toxic to spiders than to coccinellids.
