“…The results manifest that two peaks of moth population were recorded one in April 17.1 and 24.2 and second in October 25.5 and 43.4 during 1995 and 1996 respectively. More or less similar population fluctuation of male pink bollworm moths have been reported by other researchers (Rice and Reynolds, 1971;Kaae et al, 1977;Qureshi et al, 1984;Attique, 1992). However, the results presented, differ from that of Ahmad (1979) who recorded the maximum population in February-March and minimum population in April.…”

Pink bollworm (Pectinophora gossypiella) is a major pest of cotton, remained active throughout the year with minimal population during June, when temperature crossed 40EC. For monitoring its population, delta traps baited with gossyplure (sex pheromone) were used. First smaller peak appeared in April and second peak the larger one in October. The moth population pattern was observed similar during the whole year for both the years of study i.e., 1995 and 1996. The results revealed that gossyplure is an effective attractant for male moths of pink bollworm and can be used successively for monitoring seasonal emergence and population development in future period, as a tool in pest management programme. The use of sex pheromone such as gossyplure result in a substantial reduction in the number of pesticide application required for the control of bollworms during the cotton growing season.

“…The population densities were high in certain periods, mainly in July, August and September, but they peaked towards the end of September in both years. In comparable studies conducted in California, population densities of P. gossypiella were higher in July, August and early September (Rice and Reynolds 1971;Kaae et al 1977). In Egypt and Pakistan, the pink bollworm population was high in August and peaked in September (Critchley et al 1983;Qureshi et al 1993).…”

Mating disruption of the pink bollworm Pectinophora gossypiella (Saund.) (Lepidoptera: Gelechiidae) using gossyplure PB-rope dispensers in cotton fields

et al. 2004

The effects of mating disruption on population densities and percentage of damage of the pink bollworm Pectinophora gossypiella (Saunders) were investigated in a cotton field in central Greece, in 1992 and. A 10-ha field was divided in two parts of 5 ha each. PB-rope dispensers were installed in midseason in one part, whereas the other was used as a control field. Catches of pink bollworm moths in pheromone-baited traps and damage caused were recorded in both the treated and control fields. Results showed that moth catches were highly reduced in the treated field and, therefore, mid-season installation of dispensers was successful. Damage (%) was significantly less in the treated compared with the control field. Consequently, the field size of 5 ha seems to be adequate for the effective implementation of mating disruption.

“…Several researchers have reported that emergence in fields begins in early March, peaks in early May with a possible second peak in late May, and is nearly completed during June in Texas (Brazzel andMartin 1959 , Fife 1961 ) , in southern California (Rice and Reynolds 1971 ) , and in Arizona (Watson et al 1973, Wene et al 1961 ) . However, Fye ( 1979 ) reported substantially later emergence through August in insectary studies in Arizona.…”

Pink bollworm: factors affecting survival of diapause larvae and emergence of overwintered moths in the spring in Central Arizona

Survival of pink boilworm, Pectinophora gossypiella (Saunders), larvae during diapause and emergence of moths in the spring was reduced about 50 percent by winter and early spring irrigations. Fewer moths emerged from buried bolls than from bolls above or on the soil surface, and earlier burial of bolls caused higher mortality than later burial. Moths emerged earlier and faster from irrigated cages than from nonirrigated. Moths developing from larvae in bolls emerged more slowly than those from free larvae or from larvae that had cut out of bolls. Other factors, such as variety of cotton, date of collection, and chemical termination, had no consistent effect on survival or emergence patterns. A reevaluation of these results and analysis of the data also showed that accumulated heat units may provide a more consistent indication than calendar date of time of emergence KEYWORDS: cotton, Pectinophora gossypiella (Saunders), pest control (cultural), pink boilworm This publication reports research involving pesticides.
