Aerial psyllid (Hemiptera: Psylloidea) detection and monitoring using suction traps in Britain: population observations, new species found and a revised British checklist

Type: Paper
Synopsis:
The Psylloidea contains species that can transmit pathogens to plants, including important
agricultural crops e.g. the proteobacterium 'Candidatus Liberibacter solanacearum' (CaLsol) to
potatoes. To obtain a better understanding of British psyllid populations, a study was
conducted over two years to determine their aerial incidence and diversity using an existing
network of 12.2 m suction traps. In total, 42 species were detected in the traps. In 2015 in
England, the most common species was the grouping of Cacopsylla melanoneura and C. affinis
followed by Trioza remota (the latter being most prevalent in autumn). In contrast, in Scotland
Cacopsylla species (melanoneura, affinis, pulchra and brunneipennis) accounted for 81% of the
population in spring and summer. The yearly sampling in England in 2015 revealed that the
aerial movement of the most common species differed in their phenology. The grouping of
Cacopsylla melanoneura and C. affinis, as well as T. urticae were most common in summer
whereas T. remota was most prevalent in late autumn. Three species new to Britain: Cacopsylla
alaterni,Trioza anthrisci and Ctenarytaina spatulata were caught during sampling, in addition to
Trioza apicalis which transmits CaLsol. Following our study, the British psyllid checklist was
revised and is presented here. The potential of suction traps for monitoring and detecting psyllid species was demonstrated in Britain and confirmed by a limited assessment of catches
from a Swedish trap in which two species not present in Britain were found. These were Trioza
tatrensis and Trioza dispar.

Thisanotia chrysonuchella (Scopoli, 1763) (Lepidoptera: Crambidae): a review of the early stages
By: R. J. HECKFORD & S. D. BEAVAN
Page: 167–180
Type: Paper
Synopsis:
An account is given of the ovum and larva of Thisanotia chrysonuchella (Scopoli, 1763)
together with photographs of both, including the latter in various instars. Except for a
description of the first instar, all other accounts of the larva in the British literature appear to
be based on a German publication of 1865 that does not entirely agree with our observations.
We review cited larval foodplants, all in the Poaceae, and set out our observations on larvae
feeding on moss in captivity.
Two new European species of Cotesia Cameron, 1891 (Hymenoptera: Braconidae, Microgastrinae) parasitizing butterflies (Lepidoptera: Papilionoidea), and an unrelated synonymy in the genus
By: MARK R. SHAW & JOSE L. FERNANDEZ-TRIANA
Page: 181–195
Type: Paper
Synopsis:
Two new European species of Cotesia are described and illustrated. One (C. euchloevora
Shaw, sp. nov.) was reared from Euchloe species and close relatives and also Aplocera efformata,
and the other (C. parnassii Shaw, sp. nov.) was reared from Parnassius phoebus. Notes are given
to distinguish them from congeners. The DNA barcodes of C. euchloevora are discussed in
relation to similar barcodes for another, but morphologically clearly distinct, species Cotesia
pilicornis (Thomson). Unrelated to this, it is proposed that C. acutula (Tobias) is a junior
synonym of C. cajae (Bouché).
A review of the current status of the endemic Aricia teberdina nahizerica (Eckweiler, 1978) (Lepidoptera: Lycaenidae) in the Type Locality, Erzurum Province, Turkey
By: ONAT BAŞBAY, SÜLEYMAN SALKUTLU, HAKAN YILDIRIM, YUNUS KORKMAZ & EDDIE JOHN
Page: 196–204
Type: Paper
Synopsis:
We review the known biotopes of Aricia teberdina nahizerica in Turkey, including those
mentioned in the literature, and discuss our attempts at monitoring the effects of human-based
activities on these biotopes. Forty years have elapsed since the first description of subspecies
nahizerica (Eckweiler, 1978). During this 40-year period, and increasingly so during the past
10 years, construction and agricultural activities have increased enormously at the biotopes.
Our target species was finally found after seven years of searching that involved over 300 visits
to over 70 different sites. Although it is still possible to find the subspecies at the previously
observed biotopes, it is very clear that the increasingly negative influences caused by human
intervention will further threaten its existence in the near future. The conservation status was
determined as ‘Endangered’ in the Red List of Turkey in 2011.
Rearing records of two species of Hymenoptera: Braconidae (Macrocentrinae and Orgilinae) new to Britain
By: MARK R. SHAW
Page: 205–209
Type: Paper
Synopsis:
From material now in the National Museums of Scotland, the braconids Macrocentrus flavus
Snellen van Vollenhoven, 1878 and Orgilus anurus Thomson, 1895 are recorded from Britain
for the first time, based on reared material, and notes for their identification are given. The first
of these is also recorded from Spain, again from reared specimens. Details of British specimens
in NMS of Orgilus rugosus are also given.
Aethes bilbaensis (Rössler, 1877) (Lepidoptera: Tortricidae) new to the British Isles
By: S. D. BEAVAN
Page: 210–216
Type: Paper
Synopsis:
The first occurrence is reported in the British Isles, from Devon, of Aethes bilbaensis (Rössler,
1877). Some other Aethes species are compared and consideration is given to whether it is an
overlooked resident or an immigrant.
