| Popis: | The spotted-wing Drosophila, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae), is an invasive pest which causes important damage to fruit crops. Despite significant economic and environmental harm, no satisfactory means of control have been found yet. One interesting option for the biological control of D. suzukii is the use of dead-end trap plants. These are attractive plant species that divert the pest away from infesting the main crop while being lethal for its offspring. Here we explored the efficiency of the firethorn Pyracantha coccinea as a dead-end trap plant for D. suzukii. We conducted experiments both in controlled laboratory conditions and in growhouses, offering conditions closer to the reality of the field. Our results show that the fruits of P. coccinea are highly attractive to D. suzukii while being invariably deadly for its offspring. The infestation rate of strawberries, a very attractive fruit commonly infested by D. suzukii, was reduced by 40% when firethorn fruits were present in the set-up. We also monitored the survival of D. suzukii offspring in P. coccinea fruits and observed that mortality occurred before pupation, mainly during the 2nd larval instar, along with a darkening of the larvae’s cuticle. Our results demonstrate the potential of P. coccinea in the biological control of D. suzukii. Indeed, planting firethorn near fruit crops could offer an efficient, durable and low-maintenance solution to reduce the damages caused by D. suzukii. |
