Rearing mealybugs for use in pesticide efficacy studies for pineapple production
2011
Taniguchi, G.
A method of conducting efficacy studies for pesticide screening was developed for control of the pineapple mealybugs Dysmicoccus brevipes and D. neobrevipes. Sectioned crowns were planted individually in pots, grown for 2 to 4 months and then inoculated with cultured mealybug crawlers grown on kabocha pumpkin or butternut squash. After inoculation plants were grown for another 2 months. Individual infested plants were taken outdoors and sprayed with a test pesticide and observed for mealybug mortality over a period of 6 weeks.
