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species as having been introduced to the Hawaiian Islands with forty-six (46) species considered established based on unpublished Hawaii State Department of Agriculture records and literature published in Hawaii.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.

  • The Coccinellids (Coleoptera:Coccinellidae) Fauna in Manduwala Region, Dehradun, India
    J. Exp. Zool. India Vol. 21, No. 1, pp. 177-183, 2018 www.connectjournals.com/jez ISSN 0972-0030 THE COCCINELLIDS (COLEOPTERA:COCCINELLIDAE) FAUNA IN MANDUWALA REGION, DEHRADUN, INDIA Dinesh Kumar Bhardwaj and Jyoti Falswal Department of Zoology, Dolphin (P.G.) Institute of Biomedical and Natural Sciences, Dehradun, India. (Accepted 17 October 2017) ABSTRACT : The latitude of Manduwala in Dehradun, Uttarakhand, India is 30.321915, and the longitude is 78.026619. Dehradun, Uttarakhand, India is located at India Country. These beetles are useful because of their predaceous Nature. The specimens of this research were collected by hand picking. These are of small size and easy to capture by hand. Killing Jar is a device used by entomologists to kill captured insects quickly and with minimum damage. The Jar, typically glass, must be hermetically sealable and one design has a thin layer of hardened plaster of paris on the bottom to absorb the killing agent. The killing agent will then slowly evaporate, allowing the jar to be used many times before needing to refresh the jar. A second method utilizes a wad of cotton placed in the bottom of jar. Liquid killing agent is then added until the absorbent material is nearly saturated. The most common killing agent is Chloroform and ethyl acetate. The species belong the family Coccinellidae; Sub family- Coccinellinae, the total of 9 species, Coccinella quinquepunctata, Coccinella hieroglyphica, Coccinella transversalis, Harmonia dimidiata, Coccinella leonine, Harmonia conformis, Coccinella septempunctata, Hippodamia veriegata, Halmus chalybeus was identified. Coccinellids are the most important and powerful predators of hemipteran pests including, aphids, mealybugs, scale insects and whiteflies.

    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.
