“…Vahedi (2002) and Vahedi and Hodgson (2007) noted that the derm of mounted material showed a reticulate pattern of small humps, particularly on young specimens. A similar pattern of globular projections has been noted on adult female Matsucoccus feytaudi Ducasse (Matsucoccidae) (Foldi 2004). It is likely that these "projections" or dermal papillae allow the derm of the adult female to expand as she matures and her ovaries swell.…”

The morphology of the multilocular disc-pores from the anterior part of the body (abdominal segments I-III and all thoracic segments, dorso-venterally) of two species of Porphyrophora (P. tritici and P. cynodontis: Hemiptera: Coccoidea: Margarodidae) were examined using a scanning electron microscope. The multilocular disc-pores of both species have 1 or 2 (rarely 3) rings of evenly or unevenly distributed loculi but the more central rings are almost always incomplete. Each outer ring of the more anterior disc-pores of P. tritici was complete, with 5-13 loculi, and the inner ring had 0-4 unevenly distributed loculi. Each disc-pore of P. cynodontis had a complete outer ring of 6-9 evenly distributed loculi and an inner ring with only 0-1 loculi. A bright central zone is absent in most cases. These two species are similar in that both have a dense network of small, globular projections throughout the derm surface. These observations are discussed in relation to those of light microscope studies.

Specialization is an important attribute of a biological control agent. The maritime pine bast scale, Matsucoccus feytaudi Ducasse (Hemiptera Matsucoccidae), is an invasive species in Southeast France and the North of Italy. Iberorhyzobius rondensis Eizaguirre (Coleoptera: Coccinellidae), is a recently described ladybird species. Both adults and larvae are predaceous, feeding on egg masses of M. feytaudi, and are strongly attracted to M. feytaudi's sex pheromone. To evaluate the potential of I. rondensis as a biocontrol agent of the scale, we studied its niche breadth and prey range with emphasis on pine forests and hemipterans as tested prey. In this study, I. rondensis was found to achieve complete development only when fed on M. feytaudi egg masses (92.9% survival) and an artificial prey: eggs of Ephestia kuehniella Zeller (27.6% survival). From the 2nd instar onwards, complete development could be achieved using other prey species, although larvae had significantly higher mortality and slower development. In choice tests, M. feytaudi was the preferred prey. Surveys of the ladybird populations in the Iberian Peninsula revealed that it was found exclusively on Pinus pinaster Aiton, the sole host of M. feytaudi. The unusual specialization of I. rondensis, among other predaceous ladybirds, makes it an appropriate candidate for classical biological control of M. feytaudi.

“…Matsucoccus spp. are among the oldest known scale insects and they have no known parasitoids (Foldi, 2004). Thus if any pressure from natural enemies has constrained the evolution of the pine bast scales species this might have been from specialist predators.…”

The attraction of several adult predators, genera Elatophilus, Hemerobius and Sympherobius, to the sex pheromones of pine bast scales, Matsucoccus Cockerell, has already been demonstrated. Here, the hypothesis that the larvae of these predators are similarly attracted to the host prey sex pheromone is tested. The response of predators was tested in field trials using pine tree arenas baited with the sex pheromones of M. josephi Bodenheimer & Harpaz, M. feytaudi Ducasse and M. matsumurae Kuwana. Experiments were conducted in Israel in stands of Pinus halepensis infested by M. josephi and in Portugal in stands of P. pinaster infested by M. feytaudi, respectively. The selectivity of larvae for the three sex pheromones was tested in Petri dish arenas in the laboratory. In the field, the larval stages exhibited similar modes of attraction to those of the conspecific adults: Elatophilus hebraicus Pericart in Aleppo pine forest, E. crassicornis Reuter and Hemerobius stigma Stephens in the maritime pine forests. Laboratory choice tests confirmed the kairomonal selectivity of larvae. Both forest and laboratory tests demonstrated the response of a coccinellid of the genus Rhyzobius to the sex pheromones of M. feytaudi and M. matsumurae. A unique chemical communication system among several taxa of predators of Matsucoccus spp. was highlighted that may be attributed to their coevolution on a geological time scale.
