Abstract Susceptibility of 231 holly species, hybrids and cultivars to Florida wax scale (Ceroplastes floridensis Comstock) were evaluated on field grown plants in Tifton, Georgia. Florida wax scale have two generations/year in this region. Population ratings on different parental lines were grouped as either low populations (<10 scales/60 second count), moderate populations (11–20 scales/60 second count), high populations (21–40 scales/60 second count) and very high populations (>40 scales/60 second count). Taxa from the study rated as being least preferred (low populations) by the Florida wax scale included those with I. crenata, I. buergeri, I. glabra, I. myrtifolia, I. verticillata and I. vomitoria within parental lines. Those prone to heavy infestations were I. aquifolium, I. × attenuata, I. cassine, I. ciliospinosa, I. cornuta, I. × koehneana, I. latifolia, I. × meserveae, I. opaca, I. purpurea, I. rugosa and I. serrata. Other scale insects noted on the hollies included: Barnacle wax scale (Ceroplastes cirripediformis Comstock), Indian wax scale (Ceroplastes ceriferus (Fabricius)), European fruit lecanium (Parthenolecanium corni Bouche), Brown soft scale (Coccus hesperidum Linneaus), Tea scale (Fiornia theae Green), Latania scale (Hemiberlesia lataniae (Sign.)), and a pit scale (Asterolecanium puteanum Russell).

The Relationship

The adult females of two new species of Diaspididae (Hemiptera: Coccoidea) are described and placed in Anzaspis Henderson(previously only known from New Zealand): A. neocordylinidis Łagowska & Hodgson and A. pandani Łagowska & Hodgson.The former is close to A. cordylinidis (Maskell), currently only known from New Zealand and found on the same host plantspecies, and the latter is very close to Chionaspis pandanicola Williams & Watson, only currently known from Fiji, and alsocollected on the same host plant species. Two previously described Chionaspis species already known from Fiji, i.e. C.freycinetiae Williams & Watson and C. pandanicola Williams & Watson are transferred to Anzaspis as Anzaspis freycinetiae(Williams & Watson) comb. nov. and A. pandanicola (Williams & Watson) comb. nov., and a third species, C. rhaphidophoraeWilliams & Watson, is transferred to Serenaspis as Serenaspis rhaphidophorae (Williams & Watson) comb. nov.. The reasonsfor these nomenclatural decisions and the relationship between the scale insect fauna of Fiji and New Zealand are discussed. A key is provided to all related species in the tropical South Pacific and New Zealand.

Leaf Curl

A new species of eriococcid scale insect, Ovaticoccus amplicoxae, is described from Belize. The species has enormous hind coxae, unlike any described so far in this genus, or in related genera. In life, the species galls the leaves to such an extent that it has been impossible to identify the host plant.

This report elucidates the process of settlement by Coccus scale insects into Crematogaster plant-ant nests formed inside the hollow stems of a myrmecophytic species, Macaranga bancana, in a tropical rain forest. We collected wafting scale insect nymphs from the canopy using sticky traps and characterized the DNA sequence of the trapped nymphs. In addition, we experimentally introduced first-instar nymphs of both symbiotic and nonsymbiotic scale insects to M. bancana seedlings with newly formed plant-ant colonies. Nymphs of symbiotic species were generally carried by ants into their nests within a few minutes of introduction. Most nymphs of nonsymbiotic species were thrown to the ground by ants. Our results suggest that in Crematogaster–Macaranga myrmecophytism, symbiotic coccids disperse by wind onto host plant seedlings at the nymphal stage, and plant-ants actively carry the nymphs landing on seedlings into their nests in discrimination from nonsymbiotic scale insects.
