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.

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.

Life stages of Henosepilachna implicata (Mulsant), an economically important species of Epilachnini in India, are documented and illustrated. Mitochondrial DNA sequence data is provided for the first time for H. implicata with additional details on its host plants, distribution, and natural enemies. Its similarities and differences with other common pestiferous Henosepilachna spp. in India such as H. vigintioctopunctata (F.), H. septima (Dieke) and H. pusillanima (Mulsant) are discussed. Epilachna circularis Korschefsky, 1933 is found to be conspecific with H. implicata and is reduced to a junior synonym of the latter (new synonym). Notes are given on the distribution and natural enemies of some other species of Epilachnini of the Indian region.

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.

Abstract The yew gall midge Taxomyia taxi has been found for the first time in the Polish Carpathians. The site lies in the “Yews in Mogilno” (“Cisy w Mogilnie”) nature reserve in the western part of the Beskid Niski (Low Beskid) Mountains. The species occurs over an area of ca. 37 ha, mostly in the northern, lowest-lying parts of the reserve. 19.4% of the inspected specimens of the European yew were found to exhibit signs of feeding by gall midges. Most of the infested yews (86.7%) were barren, 8.2% were females and 5.1% males. The yew gall midges displayed no clear preferences in relation to the health status of the host plants, although yews with a healthier photosynthetic apparatus were selected more often.

Identification And Characterization

In 2016, infestation of an exotic polyphagous pest, the rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae), was documented on coconut for the first time in India. Instantaneously, RSW has garnered wide attention owing to its damage severity and rapid spread across the coconut-growing regions of the country. Hence, an attempt was made to devise a sustainable integrated pest management (IPM) module using biological control agents as a mainstay component. The present study documented the identification and characterization of a potential entomopathogenic fungal isolate for the management of RSW. An entomopathogenic fungus isolated from nymphal cadavers of RSW was identified as Simplicillium lanosoniveum based on morphological and phylogenetic analyses. A gradient of five conidial concentrations (1 × 104, 1 × 105, 1 × 106, 1 × 107 and 1 × 108 conidia/mL) of the S.lanosoniveum were tested against eggs, first instars, second to third instars and pupae of RSW. Results revealed that S.lanosoniveum is highly virulent to all developmental stages of RSW by causing mortality rates of 95.20%, 87.33%, 85.38% and 72.85%, in eggs, initial, middle and later instar nymphs of RSW, respectively, at the highest tested concentration (1 × 108 conidia/mL) at seven days after exposure. The LC50 and LT50 values of S.lanosoniveum were 4.72 × 104, 4.94 × 104, 5.11 × 105, 5.92 × 105 conidia/mL and 4.27, 4.86, 4.56, 5.89 days against eggs, initial, middle and later instar nymphs of RSW, respectively. Further, preliminary field trials with S.lanosoniveum strain at 1 × 108 conidia/mL exhibited a significant reduction in the egg and nymphal population by 57.8% and 56.3%, respectively. This report thus demonstrated that the newly isolated S.lanosoniveum is an effective pathogen at suppressing all the developmental stages of RSW. This is the first record of S.lanosoniveum infecting RSW, and it has a great potential to be developed as a mycoinsecticide.
