Data on ecology of some Hemiptera species recorded in the forest of Taygetus Mountain, Peloponnesus, Greece

Abstract

Data on ecology of the Hemiptera species found in the forest area of the Taygetus Mountain during the years 2004-2008 are presented. The scale insects Eulecanium sericeum (Lindinger) (Hemiptera: Coccidae), Nemolecanium graniformis (Wünn) (Hemiptera: Coccidae), Physokermes hemicryphus (Dalman) (Hemiptera: Coccidae), Physokermes inopinatus Danzig & Kozár (Hemiptera: Coccidae), Dynaspidiotus abietis (Schrank) (Hemiptera: Diaspididae) and the aphid Cinara confinis (Koch) (Hemiptera: Aphididae) were found infesting fir trees Abies cephalonica (Pinaceae) and the scale species Lineaspis striata (Newstead) (Hemiptera: Diaspididae) and Planococcus vovae (Nasonov) (Hemiptera: Pseudococcidae) were found on Juniperus oxycedrus (Cupressaceae). The coccids P. hemicryphus, P. inopinatus, N. graniformis and the diaspidid D. abietis complete one generation per year in the study area. The predatory species Chilocorus bipustulatus (L.), Exochomus quadripustulatus (L.), Ceratomegilla undecimnotata (Schneider), Coccinella septempunctata L. and Scymnus sp. (Coleoptera: Coccinellidae) were observed on the infested plants. The encyrtid Pseudorhopus testaceus (Ratzeburg) parasitized female adults of P. hemicryphus. The parasitization level reached 47.8% in July.

Bionomy of small spruce bud scale, Physokermes hemicryphus (Dalman) (Hemiptera: Coccidae) in Serbia

“…In Serbia, small spruce bud scale has one generation annually and overwinters as the second-instar larva on spruce branches. The same life cycle data have been recorded in Serbia (Kozarževskaja & Vlainić, 1982), Germany (Schmutterer, 1965), Greece (Santas, 1988;Stathas et al, 2011) and North America (Furniss, 2004). In Serbia, the species' reproduction is sexual, as it is in Greece as well (Santas, 1988), while in Germany (Schmutterer, 1956) and North America (Gill, 1988) its reproduction is parthenogenetic.…”

“…The number of eggs laid by female varies. The data in this study show that a female lays between 360 and 650 eggs, while in Greece the number varies from 70 to 280 (Stathas et al, 2011) and from 82 to 1486 (Santas, 1988), in Germany from 38 to 335 (Schmutterer, 1956), and in North America from 290 to 858 (Furniss, 2004).…”

“…During this study, five species were found, and P. testaceus was the most efficient of them with 28.97% parasitism. The efficacy percent reported in Germany was 70% (Schmutterer, 1965), and 76.5% (Santas, 1988) and 47.8% (Stathas et al, 2011) in Greece.…”

“…According to literature data, 18 parasitoid species have been detected on Ph. hemicryphus so far, belonging to the families Aphelinidae, Encyrtidae, Eulophidae and Pteromalidae (Noyes, 2017), while predators included species from the families Anthribidae, Coccinelidae (Coleoptera) and Chrysopidae (Neuroptera) (Schmutterer, 1965;Förster, 1973;Klausnitzer & Förster, 1976;Kosztarab & Kozár, 1983;Santas, 1988;Stathas et al, 2011). In Belgrade, Serbia, three parasitoid species have been found: M. lunatus, C. lycimniа and P. testaceus, and the predator A. nebulosus (Mihajlović & Kozarževskaja 1983).…”

Scale insect species (Hemiptera: Coccomorpha) and their natural enemies, recorded on agricultural, ornamental and forest plant species in the wider area of Messenian Province (Peloponnese, Greece), 2000 – 2020

“…in Heraklion. In Messenia, L. striata was found on Juniperus oxycedrus L. (Cupressaceae) on Taygetus Mountain in January 2007 (Stathas et al, 2011).…”
