TL;DR: The effects on specimen reproductive systems showed that the ovary was not affected, that the testicle size increased, and that the fecundity and weight of brood-masses were reduced, and the prolonging of development time may cause a phase lag in the field activity cycle.

TL;DR: Two field experiments designed as the biological check method (interference) and the paired-cage technique (exclusion) were used to evaluate the effectiveness of natural enemies in maintaining low densities of the pink pineapple mealybug, Dysmicoccus brevipes (Cockerell), in pineapple plantings in Hawaii.

TL;DR: The field results support those of the laboratory bioassays, showing that males attracted conspecific males and females and addition of plant material enhanced the attraction, and suggest that S. acupunctatus produces an aggregation pheromone.

TL;DR: The potential use of the aggregation pheromone in the development of a mass‐trapping programme as a viable pest management alternative for S. acupunctatus is discussed.

TL;DR: Y‐tube olfactometer bioassays of the compounds showed that males and females were attracted to α‐pinene, 3‐carene, γ‐terpinene and/or linalool at doses of 1 and 10 μg, while weevils were repelled by linalools at a dose of 100‰μg.
