Tree Quality

Abstract Higher temperatures and drought are key aspects of global change with the potential to alter the distribution and severity of many arthropod pests in forest systems. Scale insects (Hemiptera: Coccoidea) infest many tree species and are among the most important pests of trees in urban and rural forests, plantations and other forest systems. Infestations of native or exotic scale insects can kill or sicken trees with economic and ecosystem-wide consequences. Warming can have direct effects on the life history, fitness and population dynamics of many scale insect species by increasing development rate, survival or fecundity. These direct benefits can increase the geographic distribution of scale insects and their consequences for tree health. Warming and drought can affect scale insects indirectly by altering the quality of their host trees. Additive or interactive effects of warming and drought can change tree quality in such a way that it increases scale insect fitness and population growth. However, the effects are species- and context-dependent with some scale insect species negatively affected by drought-induced changes in tree quality. Warming and drought are often coincident in urban forests and predicted to co-occur in many parts of the world under climate change scenarios. The individual and interactive effects of these factors require further research to inform predictions and management of scale insect pests. Warming also indirectly affects scale insects by altering interactions with natural enemies. This includes changes in natural enemy phenology, community composition and abundance. In addition, warming can alter scale insect phenology or voltinism causing asynchrony with natural enemies or population growth too rapid for natural enemies to suppress. Direct and indirect effects of warming and drought on scale insects can increase the potential for some exotic species to become established and for some native species to become invasive. Unfortunately, much research on scale insects is confined to a few particularly important native or exotic pests which limits our ability to predict the effects of warming on many current or potential pests. More research is required to understand how warming and drought affect scale insects, scale insect management and the forest systems they inhabit.

A preliminary list of non-indigenous scale insect species on ornamental plants in Bulgaria and China is presented. The sampling was done between April and November, 2009, in the framework of the project “Invasive scale insects on ornamental plants in Bulgaria and China”. The insects were collected in nurseries, parks, gardens, botanical collections and greenhouses. Representatives from four families have been identified in Bulgaria, the most numerous of which are the Diaspididae (eight species), Coccidae (four species), Pseudococcidae (two species) and Margarodidae (one species). Three species of non-indigenous scale insects associated with ornamental plants were collected in China, all belonging to the family Pseudococcidae. A list of alien scale insect species on ornamental plants is given, including the sampling sites, host plants on which they were found, origin and first report in both countries.

Virulence of commercial strains of entomopathogenic nematode (EPN) Steinernema carpocapsae (Weiser), Steinernema feltiae Filipjev and Heterorhabditis bacteriophora Poinar (Rhabditida: Steinernematidae, Heterorhabditidae), were tested on young females of Pulvinaria hydrangeae Steinweden, Partenolecanium corni (Bouché) and Coccus pseudomagnoliarum (Kuwana) (Hemiptera, Coccidae) and a native strain of H. bacteriophora was tested on citricola scale, C. pseudomagnoliarum. The laboratory tests were carried out in small plastic Petri dishes with infective juveniles (IJ) applied on filter paper covering the bottom. Results showed that all EPN tested were virulent to all three soft scale insect species. Recorded mortality of insects at the highest concentration of approximately 50 IJ per cm2 exceeded 64% in all combinations of nematode and scale species tested. Within the same nematode concentration, scales’ mortality of 90% and above was recorded for P. corni with all nematode species, P. hydrangeae with S. carpocapsae (Nemastar) and C. pseudomagnoliarum with native H. bacteriophora strain. All scale species were good hosts for all nematode species. This is the first report of EPNs to parasitize soft scale insects and one of the few among Coccoidea. The level of parasitism recorded is promising for potential use in management of scale insects.

A list of the scale insects (Homoptera: C occoidea) recorded by the authors for the Greek island of C rete is reported. This includes twenty-seven species new to the island The most interesting records are Kermes palestiniensis Balachowsky (Kermesidae), only recorded previously from Israel, and Getulaspis bupleuri (Marchal) (Diaspididae), only known previously from North A frica and the Middle E ast. With the present additions, the number of scale insect species recorded on C rete has reached 82. A revised check list of the scales presently known from the island is also provided.

Abstract Background: This study was realized for more than four years (from 2014 to 2018) in olive groves of northern Tunisian governorates. Scale insect samples were collected from leaves, stems and fruits.Results: An annotated list of 22 scale insect species has been recorded. These species divided into 4 families. The family Diaspididae is the most species-rich, with 14 species in 9 genera; Coccidae contains 4 species in 3 genera; Pseudococcidae contains 3 species in 3 genera; and Asterolecaniidae contains 1 species in 1 genus.Conclusions: This paper contains 3 species recorded for the first time in the Tunisian fauna: Saissetia coffeae (Walker), Diaspidiotus ostreaeformis (Curtis) and Lepidosaphes conchiformis (Gmelin).

The checklist of scale insect species recorded from Kenya comprises 14 families, 128 genera and 304 species, of which 207 (68.0%) are probably of African origin, 91 (29.9%) have been introduced from outside Africa and six (2.0%) are of unknown origin. Out of the 207 African species, only 11 (5.3%) have been recorded damaging plants, whereas out of the 91 introduced species, 45 (49.5%) have caused or are highly likely to cause plant damage in Kenya. The most economically important scale insect families in Kenya are (in order of importance) the Pseudococcidae, Coccidae and Diaspididae. Four new combinations are made: Eurycoccus glomerulus De Lotto is transferred to Trionymus, as Trionymus glomerulus (De Lotto) comb. n.; Trionymus sativus James is transferred to Paracoccus, as Paracoccus sativus (James) comb. n.; Pseudococcus masakensis James is transferred to Nipaecoccus as Nipaecoccus masakensis (James) comb. n., and Spilococcus commiphorae De Lotto is transferred to Paracoccus, as Paracoccus commiphorae (De Lotto) comb. n.

Iran is situated at the junctions of the Palaearctic and Oriental zoogeographical regions, and the Caspian, Baluchi and Irano-Tiranian floral zones, so it has a very diverse scale insect fauna. Scale insects (Hemiptera: Coccomorpha) are economically important in forestry, agriculture and horticulture. This taxonomic account of the armoured scales (Diaspididae) of Iran is the first of three works planned to cover all the scale insects in the country. It provides a resource for accurate laboratory identification of all the species known to occur in Iran or that are likely to be found there. Keys to the families of scale insects found in Iran, and to the 49 genera and 144 species of Diaspididae found there, are provided. Detailed line drawings of all the species known to occur in Iran are provided to facilitate identification. These are accompanied by detailed descriptions, distribution data, information on natural enemies, economic importance and host-plants recorded in Iran. The main purpose of the work is to provide agricultural entomologists concerned with pest control and quarantine inspection worldwide with a reliable means of species identification.

Number Of Species

Scale insects (Hemiptera: Coccoidea) of Upper SilesiaFaunistic research conducted in Poland for over 80 years has led to the discovery of 143 species of scale insects that live in the natural environment. The state of knowledge of the coccoid fauna of individual areas is uneven, however, 83 species of scale insects from 8 families were collected in Upper Silesia (Górny Śląsk). Upper Silesia is the region in Poland with the fourth-largest number of species; it is preceded by the Kraków-Wieluń Upland (94 species), Roztocze (88) and the Świętokrzyskie Mts. (86). Two of the species collected in this area -Trionymus hamberdi and Volvicoccus stipae- are known only from this region. The paper gives a list of scale insect species collected in Upper Silesia together with information on their localities.
