Interspecific competition between Anagyrus pseudococci and Leptomastix dactylopii, parasitoids of the vine mealybug Planococcus ficus

Carbon dioxide (CO2) is one of the primary factors driving climate change impacts on plants, pests, and natural enemies. The present study reports the effects of different atmospheric CO2 concentrations on the vine mealybug Planococcus ficus (Signoret) and its parasitoid wasp Leptomastix dactylopii (Howard). We investigated the life-history parameters of both species on grapevine Vitis vinifera (L.) plants grown under elevated (eCO2) and ambient (aCO2) CO2 levels in a greenhouse and in a vineyard free-air carbon dioxide enrichment (FACE) facility. The greenhouse experiments with an eCO2 level of around 800 ppm showed a significant increase in survival rates, a strong trend towards declining body size, and an increasing fecundity of female mealybugs, while fertility and development time did not change. However, none of these parameters were altered by different CO2 concentrations in the VineyardFACE facility (eCO2 level around 450 ppm). On the other hand, the parasitism success, development time and sex ratio of L. dactylopii, reared on P. ficus under eCO2 or aCO2, varied neither in the greenhouse nor in the FACE facility. These results suggest that future CO2 levels might cause small-scale changes in vine mealybug fitness; however, this is not necessarily reflected by parasitoid performance.

Morphological And Molecular Characterization

Some vine mealybug, Planococcus ficus (Signoret) populations in Tunisian vineyards have been morphologically and genetically characterized. The morphological examination was based on the main distinctive characteristics of species of Planococcus, namely the number and distribution of the multilocular disc pores and tubular ducts on the adult female. This showed the existence of two different vine mealybug populations in Tunisia. Likewise, in the molecular analyses, two separate clades were revealed in the neighbour-joining phylogenetic tree, supporting the morphological studies and suggesting that there are two distinct populations of P. ficus on grapevine in Tunisia.

Vine Mealybug

The vine mealybug, Planococcus ficus (Signoret), and the citrus mealybug, Planococcus citri (Risso), are currently the most economically important pseudococcids in vineyards in Italy (Dalla Montà et al., 2001). Pl. ficus is also considered to be a key pest in many other countries (Ben-Dov, 1994). The two species cause severe damage to the host plant, and significantly reduce the crop due to the production of honeydew, which allows the growth of sooty molds, and to their potential as virus vectors. The vine mealybug, in particular, is known to transmit grapevine leafroll and corky-bark diseases (Engelbrecht & Kasdorf, 1990; Tanne et al., 1989).
