Beetles, butterflies and bibliophilia: the entomological legacy of Robert Wylie Lloyd

By: LAURENCE M. COOK

Page: 3–14

Type: Paper

Synopsis:
Robert Wylie Lloyd (1868–1958) made major contributions to the holdings of the Entomology Department of the Manchester Museum. Biographical details are provided for this remarkable man, the nature of his donations is described and his motivations in giving them discussed. The breadth and extent of these collections makes them a valuable resource to which modern methods of analysis could be applied. For half a century he owned and influenced the Entomologist’s Monthly Magazine.

Identity and biology of Aganaspis daci (Weld) (Hymenoptera: Figitidae), recently introduced to Egypt for biological control of Bactrocera zonata (Diptera: Tephritidae)

Page: 17–37

Type: Paper

Synopsis:
The peach fruit fly, Bactrocera zonata (Saunders, 1841), (Diptera: Tephritidae), is a serious polyphagous pest of tropical and subtropical fruits. In Egypt, the fly was first detected in 1997 and has since become widespread over most of the Egyptian provinces, causing serious damage to many fruit crops, particularly mango, guava, peach, apricot and citrus. In 2008, the larval-pupal koinobiont endoparasitoid, Aganaspis daci (Weld, 1951) (Hymenoptera: Figitidae, Eucoilinae) was introduced to Egypt via Hawaii for evaluation. The parasitoid is a dominant natural enemy of several Bactrocera species from Southeast Asia, the native region of B. zonata. To evaluate the potential of A. daci for biocontrol of B. zonata, this study investigated distinguishing features of A. daci in different stages, developmental periods, reproductive output, and optimal rearing protocols under laboratory conditions of 25±1°C, 54– 65% RH, and 14L:10D photoperiod, using B. zonata as hosts. The parasitoid Aganaspis daci went through four instars and developed into the ectoparasitic phase late in the third instar, as the larva developed one pair of functional thoracic spiracles. Total developmental period averaged 23.3 days, and males eclosed two days earlier than females. Realized fecundity of mated females averaged 39.6 offspring per female (range 32 – 55) and progeny sex ratio was 1:1. Longevity of honey fed females and males averaged 18.8 and 17.3 days, respectively. A. daci showed relative potential as a biological control agent against B. zonata in Egypt and was propagated for several generations before it was approved for release in 2009. Field recovery was reported one month following its liberation in guava orchard at Al-Arish district, North Sinai Province, with 1.6 – 8% initial rate of parasitism. Further studies, on its adaptation to the new Egyptian environment and efficacy against B. zonata under field conditions are in progress. This study provides important baseline information on the morphological and biological attributes of A. daci and the rearing method provides a basis for the development of a mass rearing protocol for augmentative parasitoid releases.

On the subgeneric placement of Andrena kraussi Michener (Hymenoptera: Andrenidae)

By: MICHAEL S. ENGEL

Page: 38–42

Type: Paper

Synopsis:
A new subgenus is described for Andrena kraussi Michener (Andreninae) from Panama and Costa Rica, as Zophandrena subgen. n. Modified couplets to the existing key to New World subgenera of Andrena Fabricius are provided in order to properly identify the group.

Studies of Ptiliidae (Coleoptera) in the Spirit Collection of the Natural History Museum, London 4: new records and species collected by M.E. Bacchus and others in Sabah (Borneo) in 1977

By: MICHAEL DARBY

Page: 43–58

Type: Paper

Synopsis:
This paper is based on a collection of 220 Ptiliidae made by M.E. Bacchus of the Coleoptera Section of the Natural History Museum, London (NHM), and others, in Sabah (Borneo) 28 August – 7 November 1977. Ten new species are described and figured: Sindosium bacchusi sp. n., Dipentium latum sp. n., Bambara pumilio sp. n. Baeocrara minima sp. n., Acrotrichis agricola sp. n., Acrotrichis bubalus sp. n., Acrotrichis irregularis sp. n., Acrotrichis kinabaluensis sp. n., Acrotrichis subagricola sp. n. and Acrotrichis telupidensis sp. n., and new records and information provided for Bambara frosti Dybas and Acrotrichis britteni Johnson.

By: PETER N. BUHL

Page: 59–64

Synopsis:
Allotropa delottococci sp. n., a parasitoid of the citrus fruit pest Delottococcus aberiae (De Lotto), is described from South Africa. A key to known Afrotropical species of Allotropa Förster is provided.

Macrotylus (Alloeonycha) xantii Günther, 2018, (Hemiptera: Miridae, Phylinae) new to Portugal, with a description of the female

By: STUART FOSTER

Page: 65–69

Type: Paper

Synopsis:
The plant bug Macrotylus (Alloeonycha) xantii Günther, 2018, is reported as new to Portugal from the Algarve. This species was described from a single male specimen captured on dry grass in a calcareous area of Andalusia, Spain. The female was previously unknown, so the presence of both sexes in reasonable numbers on sparsely vegetated sandy substrate in Portugal extends its known range and habitat preferences, and has enabled the female to be described.
