The scale insect Kermes echinatus Balachowsky (Hemiptera, Coccoidea, Kermesidae) was recorded on Quercus ilex in November 2012 in Kalamata and in December of the same year on the same host species in Athens. Quercus ilex is recorded for the first time as the host of this scale. This scale is first recorded in continental Greece. The population of the scale in both areas consisted mainly of first instar nymphs, whereas in Kalamata individuals of the scale in advanced developmental stages were recorded. Preliminary studies indicate that natural enemies are active against K. echinatus. Moultings of larvae and pupae and adults of Chilocorus bipustulatus L. (Coleoptera: Coccinellidae) were found on colonies of the scale. Parasitoid exit holes were recorded on female adults of the scale. Some data on morphology and infestation of the scale on Q. ilex are given.

The notoriously destructive and invasive soft scale, Ceroplastes cirripediformis Comstock (Hemiptera: Coccomorpha: Coccidae), is recorded for the first time from India. The scale is redescribed to facilitate its identification and information on its host range, natural enemies and distribution is provided. An identification key to the Indian species in this genus is given. Management options in the event of an outbreak are discussed briefly. The establishment of this scale insect warrants special attention in India as it is a potentially damaging plant pest and has a broad host range across many plant families.

After the first record in 2008 in Southeast Italy, the alien invasive and quarantine pest Aleurocanthus spiniferus (orange spiny whitefly—OSW) has gradually spread throughout Europe, infesting several new host plants in addition to the known hosts. Molecular characterization of some Italian populations and a newly found Albanian population highlighted two different haplotypes invading Europe, belonging to one of the haplogroups previously recorded in China. A predator was recorded for the first time in several fields in Italy in association with OSW and other whitefly species. It was successively identified through a morpho-molecular characterization as a Nearctic member of the tribe Serangiini, the ladybird beetle, Delphastus catalinae. This predator represents a promising biocontrol agent to manage A. spiniferus outbreaks in Italy and other invaded countries.

Sangicoccus sp. nr. truncatispinus (Reyne) (Eriococcidae: Homoptera) is recorded for the first time as a major pest of coconut palms in the Philippines. It is   also the first record among the coconut growing areas in the world. It sucks the plant sap resulting to chlorosis of leaves. Furthermore, honeydew droplets exuded by the pest accumulated on upper leaf surfaces become substrate for sootymolds.   The severe infestation observed in late 1980’s already spread to 6 out of 8 municipalities of the southern second district of Palawan. Presently, crop losses are estimated to reach 53% of the nut yield. The prevailing easterly and westerly wind directions of 1-5 m/sec coupled with the dense manner of planting enabled first instar nymphs (crawlers) to spread to other palms. The long dry spell also favored the proliferation of Sangicoccus sp.bv.   Controlling the spread and outbreak of this pest seems to be difficult as it thrives on eleven alternate hosts. Ant attendance contributed to dispersal and protection from natural enemies. Moreover, field population of ten predatory species remained minimal. Possible strategies for its control are presented.

Filarid nematodes are transmitted by arthropod vectors. In the vertebrate host, they inhabit the cardiovascular, pulmonary, and lymphatic system. Although most bird infections are not considered pathogenic, there may be an impact on fitness. Blood smears were performed to verify the intensity of the infection and to morphometrically analyse and describe the microfilariae found in individuals of Antilophia galeata captured in a fragment of the Cerrado forest. The microfilariae were photographed, and morphometry analysis was performed using the ImageJ software. One individual was infected (14.2%; n = 7) but with a high intensity of infection (42 microfilariae). It is suggested that the microfilariae found belong to the genus Eufilaria spp., since all specimens presented the diagnostic characteristics of the taxon (absence of sheath, pointed tail, and length less than 200 μm). This is the first time that microfilariae parasitising A. galeata have been recorded. Considering that microfilariae records are rare in Brazilian wild birds, this record may be useful to support further studies and contribute to the understanding of the conservation of the host species.

Of Greece

Physokermes hemicryphus (Dalman) is an important honeydew producing scale insect useful to apiculture. It lives mainly on Abies cephalonica Loud. and to a lesser degree on Abies borisii regis Mattf. These fir trees exist in most fir forests of Greece. It has one generation per year. Overwintering takes place in the second instar nymph. The female overwinters under the bud scales of the forks of the fir host and the male on the needles. Adults appear in spring and crawlers in July. In August the population consists mainly of first instar nymphs. The second instar nymphs start to appear in August and by late October the whole population is at the second nymphal instar, which is the overwintering one. The insect occurs in the fir forests of Greece every year but its population level fluctuates, due to weather conditions and biological factors (parasites, predators). The coexistence on the same host plant of P. hemicryphus with the scale Eulecanium sericeum (Lindiger) and the aphid Milldams abietinus (Koch) prevents the visit of honeybees to fir trees. On the other hand it favours the augmentation of the P. hemicryphus population. Four parasites were found, from which the Encyrtidae Pseudorhopus testaceus (Razz.) and Microterus lunatus (Dalman), are recorded for the first time in Greek fauna.

The Psyllidae family is the most diverse within Psylloidea, with more than 1,300 species worldwide. Some psyllid species are important pests mainly of fruit trees, forest and ornamental plants. Despite being an economically relevant group, there are few studies on its biology, geographic distribution, natural enemies or host plant associations for many Argentinean psyllid species. This work records one species from Argentina for the first time, extends the distribution of another two psyllid species and provides information on host plants.
