“…Defence provided by attendant ants can nullify the effectiveness of aphid predators (Powell & Silverman 2010 ). In laboratory experiments, Aphis gossypii was tended by the red imported fi re ant, Solenopsis invicta , which was killing both adults and larvae of Hip.…”

“…On the other hand, Powell and Silverman (2010) reported that Aphidius colemani Viereck (Hymenoptera: Braconidae) were negatively impacted by L. humile and Tapinoma sessile (Say). In general, we may have two contrasting effects of ant attendance on parasitoids: ants disturb parasitoids but, on the other hand, increased populations of Hemiptera might result in potentially more hosts and eventually to higher parasitoid populations.…”

Although ants act as plant biotic defences, in agricultural ecosystems they are often associated with outbreaks of honeydew-producing pests mainly due to the protection they offer to the plant feeders in exchange for honeydew. In such an interaction ants may alter the abundance, diversity and community structure of predators and parasitoids. In the present study, we conducted ant-exclusion experiments in three commercial citrus orchards, each one dominated by one ant species (Pheidole pallidula, Lasius grandis or Linepithema humile) during two consecutive years (2011 and 2012). We then compared the abundance, species richness, diversity and community structure of predators and parasitoids between the antallowed and ant-excluded treatments. A total of 176,000 arthropods belonging to 81 taxa were captured and identified. Regarding abundance, our results showed a species specific response between treatments. When examining functional groups, in the ant-allowed treatment, seven species of predators decreased and four increased in abundance, whereas four species of parasitoids decreased and 18 increased in abundance. The species richness (S) was significantly lower for predators and higher for parasitoids in the ant-allowed treatment. The Shannon diversity index (H) was not different between treatments in the case of predators, whereas in the case of parasitoids diversity was significantly higher in the antallowed treatment. Finally, the community structure of predators and parasitoids was not significantly different between treatments. These results suggest that ants in the citrus agroecosystem are not associated with a dramatic decrease in natural enemy abundance or biodiversity; on the contrary ants were associated with increased parasitoid species richness and diversity. Despite the fact that ants have no negative impact on the abundance and diversity of predators and parasitoids at the community level their impact on specific natural enemy species, mainly predators, may explain the highest pest densities associated with ants in citrus.

Ant–hemipteran association decreases parasitism of Phenacoccus solenopsis by endoparasitoid Aenasius bambawalei

1. Mutualism between ants and honeydew‐excreting hemipterans is ubiquitous in the ecosystem. It is widely accepted that ant tending facilitates the colony growth of hemipterans by protecting them from predators and parasitoids. However, few studies have explored how ant tending helps defend against natural enemies. 2. Ghost ant Tapinoma melanocephalum and the invasive mealybug Phenacoccus solenopsis have a close mutual relationship. Previous studies have shown that ghost ant tending can definitely reduce parasitism and visit frequency of Aenasius bambawalei, the dominant endoparasitoid of P. solenopsis. However, the ghost ant workers seldom attack the parasitoids. It is still unclear how the ghost ant adversely affects parasitoids. This study explored the mechanism underlying the impacts of ants on natural enemies of the mealybugs. 3. Honeydew produced by P. solenopsis was an attractant to A. bambawalei. Parasitoids exhibited less searching activity, shorter longevity and lower parasitism when supplied with less honeydew. Aenasius bambawalei showed significant avoidance of pygidial gland secretions and visual cues of ghost ants. Parasitism in plants treated with 6‐methyl‐5‐hepten‐2‐one, actinidine, and gland extracts was significantly lower than that in plants treated only with solvents (paraffin oil or double‐distilled water). 4. It is concluded that honeydew consumption by ghost ants could negatively influence the performance of parasitoids. The pygidial gland secretions and visual cues of ghost ants also significantly inhibit the parasitism. These results may contribute to a better understanding of the regulation mechanism in ant–hemipteran–enemy interactions.
