EENY-170 Ladybirds, Ladybird beetles, Lady Beetles, Ladybugs of Florida, Coleoptera: Coccinellidae1 J. H. Frank R. F. Mizell, III2 Introduction Ladybird is a name that has been used in England for more than 600 years for the European beetle Coccinella septempunctata. As knowledge about insects increased, the name became extended to all its relatives, members of the beetle family Coccinellidae. Of course these insects are not birds, but butterflies are not flies, nor are dragonflies, stoneflies, mayflies, and fireflies, which all are true common names in folklore, not invented names. The lady for whom they were named was "the Virgin Mary," and common names in other European languages have the same association (the German name Marienkafer translates Figure 1. Adult Coccinella septempunctata Linnaeus, the to "Marybeetle" or ladybeetle). Prose and poetry sevenspotted lady beetle. Credits: James Castner, University of Florida mention ladybird, perhaps the most familiar in English being the children's rhyme: Now, the word ladybird applies to a whole Ladybird, ladybird, fly away home, family of beetles, Coccinellidae or ladybirds, not just Your house is on fire, your children all gone... Coccinella septempunctata. We can but hope that newspaper writers will desist from generalizing them In the USA, the name ladybird was popularly all as "the ladybird" and thus deluding the public into americanized to ladybug, although these insects are believing that there is only one species. There are beetles (Coleoptera), not bugs (Hemiptera). many species of ladybirds, just as there are of birds, and the word "variety" (frequently use by newspaper 1.

  • COLEOPTERA COCCINELLIDAE) INTRODUCTIONS and ESTABLISHMENTS in HAWAII: 1885 to 2015
    AN ANNOTATED CHECKLIST OF THE COCCINELLID (COLEOPTERA COCCINELLIDAE) INTRODUCTIONS AND ESTABLISHMENTS IN HAWAII: 1885 to 2015 JOHN R. LEEPER PO Box 13086 Las Cruces, NM USA, 88013 [email protected] [1] Abstract. Blackburn & Sharp (1885: 146 & 147) described the first coccinellids found in Hawaii. The first documented introduction and successful establishment was of Rodolia cardinalis from Australia in 1890 (Swezey, 1923b: 300). This paper documents 167 coccinellid species as having been introduced to the Hawaiian Islands with forty-six (46) species considered established based on unpublished Hawaii State Department of Agriculture records and literature published in Hawaii. The paper also provides nomenclatural and taxonomic changes that have occurred in the Hawaiian records through time. INTRODUCTION The Coccinellidae comprise a large family in the Coleoptera with about 490 genera and 4200 species (Sasaji, 1971). The majority of coccinellid species introduced into Hawaii are predacious on insects and/or mites. Exceptions to this are two mycophagous coccinellids, Calvia decimguttata (Linnaeus) and Psyllobora vigintimaculata (Say). Of these, only P. vigintimaculata (Say) appears to be established, see discussion associated with that species’ listing. The members of the phytophagous subfamily Epilachninae are pests themselves and, to date, are not known to be established in Hawaii. None of the Coccinellidae in Hawaii are thought to be either endemic or indigenous. All have been either accidentally or purposely introduced. Three species, Scymnus discendens (= Diomus debilis LeConte), Scymnus ocellatus (=Scymnobius galapagoensis (Waterhouse)) and Scymnus vividus (= Scymnus (Pullus) loewii Mulsant) were described by Sharp (Blackburn & Sharp, 1885: 146 & 147) from specimens collected in the islands. There are, however, no records of introduction for these species prior to Sharp’s descriptions.

  • Black Scale Saissetia Oleae (Olivier, 1791)
    EENY620 Black Scale Saissetia oleae (Olivier 1791) (Insecta: Hemiptera: Coccoidea: Coccidae)1 Morgan A. Byron, Jennifer L. Gillett-Kaufman, and Sandra A. Allan2 Introduction Synonymy The black scale, Saissetia oleae (Olivier 1791) (Hemiptera: Coccus oleae Olivier (1791) (ITIS 2014) Coccidae) is an important pest of citrus and olive trees. Originally from South Africa, this scale is now distributed Distribution worldwide. In Florida, black scale is found on citrus (Citrus Black scale has a cosmopolitan distribution, with records in spp.), cultivated olive (Olea europaea L.), avocado (Persea Europe, Asia, Africa, Australasia, the Pacific Islands, and in americana Mill.), and many popular landscape plants. the Americas (CABI 1954). It is likely that black scale, like many invasive pests, was imported to the United States on infested nursery plants. Based on their small size and the unique life history of scale Biology insects, these insects are difficult to detect and control. Female black scales deposit eggs from April to September and, like other species in the genus Saissetia, protect them beneath the body until they hatch. Each female can lay from a few hundred to over 2,500 eggs (Tena et al. 2007). Incubation time for the eggs varies due to temperature, with eggs laid in the summer hatching in 16 days and eggs in the winter taking up to six weeks to hatch. Black scale typically has one or two generations per year, but three generations have been observed in certain regions. Reproduction is largely parthenogenetic (a type of asexual reproduction where eggs develop without fertilization), although males Figure 1. Adult female black scales, Saissetia oleae (Olivier) on have been reported.

In Europe, it is an indige- nous species, commonly found on various plants, including conifers. The present study examined whether A. andersoni can develop and reproduce while feeding on two key pests of ornamental coniferous plants, i.e., Oligonychus ununguis (Jacobi) and Pentamerismus taxi (Haller). Pinus sylvestris L. pollen was also tested as an alternative food source for the predator. Both prey species and pine pollen were suitable food sources for A. andersoni. Although higher values of population parameters Citation: Puchalska, E.; were observed when the predator fed on mites compared to the pollen alternative, we conclude that Zagrodzki, S.K.; Kozak, M.; pine pollen may provide adequate sustenance for A.

    POPULATION ECOLOGY AND INTEGRATED MANAGEMENT OF SOFT WAX SCALE (CEROPLASTES DESTRUCTOR) AND CHINESE WAX SCALE (C. SINENSIS) (HEMIPTERA: COCCIDAE) ON CITRUS A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University Peter L. La Lincoln University 1994 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Ph.D. POPUlATION ECOWGY AND INTEGRATED MANAGEMENT OF SOFT WAX SCALE (CEROPLASTES DESTRUCTOR) AND CHINESE WAX SCALE (c. SINENSIS) (HEMIPTERA: COCCIDAE) ON CITRUS Peter L. La Soft wax scale (SWS) Ceroplastes destructor (Newstead) and Chinese wax scale (CWS) C. sinensis Del Guercio (Hemiptera: Coccidae) are indirect pests of citrus (Citrus spp.) in New Zealand. Honeydew they produce supports sooty mould fungi that disfigure fruit and reduce photosynthesis and fruit yield. Presently, control relies on calendar applications of insecticides. The main aim of this study was to provide the ecological basis for the integrated management of SWS and CWS. Specific objectives were to compare their population ecologies, determine major mortality factors and levels of natural control, quantify the impact of ladybirds on scale populations, and evaluate pesticides for compatibility with ladybirds. Among 57 surveyed orchards, SWS was more abundant than CWS in Kerikeri but was not found around Whangarei. Applications of organophosphates had not reduced the proportion of orchards with medium or high densities of SWS. Monthly destructive sampling of scale populations between November 1990 and February 1994 was supplemented by in situ counts of scale cohorts. Both species were univoltine, but SWS eggs hatched two months earlier than those of CWS, and development between successive instars remained two to three months ahead.
