Abstract
Objectives: The present study was carried out to investigate the biology of Maconellicoccus hirsutus on Alba variety of mulberry under laboratory conditions and comparative infestation of M. hirsutus on Alba and purple varieties of mulberry under field conditions. Methods/Statistical Analysis: Mean and standard error was used to describe the results. Findings: The results indicated that the fecundity of M. hirsutus varied from 221 to 232 varied eggs per female. The pest completed its life cycle in 29.08 to 32.51 days. The infestation of M. hirsutus on different mulberry variety showed that purple variety was resistant than Alba variety with pest population of 8.43 ± 0.33 mealybugs per 10 cm twig compared with 9.73 ± 0.93 mealybugs on Alba variety. Application/Improvements: M. hirsutus is a serious polyphagous pest insect of mulberry and other plants. Therefore, it is suggested that detailed studies on population dynamics, natural enemies and population management of this mealybug should be carried out under agroecological conditions of Sindh, Pakistan. Keywords: Biotic and Abiotic, Maconellicoccus hirsutus, Mulberry Mealybug
Highlights
Mulberry, Morus alba L., is used for rearing of silkworms and wood around the world, including Pakistan[1,2]
Maconelicoccus hirsutus is very important and serious insect pest of mulberry in Pakistan causing damage to mulberry of plants. The severity of this pest has been reported by many authors such as[16] carried out a survey and reported that 15-30% plantation of mulberry was infested by M. hirsutus
In17 reported that M. hirsutus was a major pest of mulberry in India and caused a viral disease in mulberry called Tukra
