| Abstract:
Control of the big-headed ant, Pheidole megacephala, in pineapple plantations is essential to the prevention of economically significant infestations of pineapple mealybugs, which have a close symbiotic relationship with this ant species. At a demonstration site for growers, bait stations with Amdro were placed around the perimeter of a newly planted pineapple field for a period of one year. This treatment prevented big-headed ants from migrating into the field and establishing colonies. A nearby untreated control site became infested on several occasions and required treatment with ant baits and a single application of Diazinon for mealybug control. | |
