Methods for rearing Diabrotica speciosa (Germar) and D. viridula (F.) in the laboratory, and their vital statistics are described. These Luperini are pests of several crops in South and Central America, and there was no pre­ vious work describing suitable methods for obtaining the numbers required for the mass production of parusitoids, assessing pathogens, or conducting host specificity studies. Handling of immatures and adults was reduced to a minimum, and materials used were inexpensive, reducing costs, labor time, and mortality related to manipulation. Larvae were reared on maize seedlings in a soil mixture, and adults were fed a dry diet. Oviposition was obtained in cups with corn seedlings wrapped in black cloth; eggs were harvested by rinsing them off the cloths with water, and sown by squirting them into maize cultures with plastic pipettes. Percentage of hatch, survival from egg to adult, and number of eggs laid per female were the highest cited yet forD. speciosa %,25.9%, %, (D. speciosa: 92.6 and 1164 respectively;D. viridula: 91 %,25 and "1271 respectively), and sirnilar for both species. D. viridula proved to be a more vigorous species than D. speciosa, with a longer average Iife span, and a slightly higher egg production, at least in present laboratory conditions. KEY WORDS.

Cria enlaboratorio y estadisticas vitales de Diabrotica speciosa y Diabrotica viridula (Coleoptera: Chrysomelidae), dos especies de vaquitas sudamericanas plagas de cultivos, Se describen metodos para la cria en labora­ torio deDiabrotica speciosa (Germar) y Diabrotica viridula (F.)y sus estadisticas vitales. Estos Luperini son plagas de varios cultivos en America del Sur y Central, y no habia trabajos previos describiendo metodos adecuados para obtener las cantidades de adultos y larvas necesarias para crías rnasivas de enemigos naturales, estudios de patógenos,o pruebas de especificidad de enemigos naturales. EI manipuleo de inmaduros y adultos, y su mortalidad asociada, fueron reducidos alminimo. Los materiales util izados fueron de bajo costo, y se redujeron las horas hombre. Las larvas se alimentaron de plantulas de maiz y los adultos de una dieta seca. Se obtuvieron puestas en recipientes con plantulas de maíz envueltas con rectangulos de tela negra hu­ medecida: los huevos se cosecharon mediante chorros de agua de los trozos de tela y se sembraron en los cultivos de rnaiz mediante pipetas plasticas .. EI porcentaje de eclosión, supervivencia de huevo a adulto, y promedio de hue­ % vos por hembra fueron simi lares en ambas especies (D. speciosa: 92,6 , %, 25,9 Y 1164 respectivamente: D. viridula: 91%, 25% Y 1271 respectiva­ mente), y los mas altos obtenidos en laboratorio hasta ahora para D. speciosa. 239 Rev.

  • Diabrotica Speciosa Primary Pest of Soybean Arthropods Cucurbit Beetle Beetle
    Diabrotica speciosa Primary Pest of Soybean Arthropods Cucurbit beetle Beetle Diabrotica speciosa Scientific name Diabrotica speciosa Germar Synonyms: Diabrotica amabilis, Diabrotica hexaspilota, Diabrotica simoni, Diabrotica simulans, Diabrotica vigens, and Galeruca speciosa Common names Cucurbit beetle, chrysanthemum beetle, San Antonio beetle, and South American corn rootworm Type of pest Beetle Taxonomic position Class: Insecta, Order: Coleoptera, Family: Chrysomelidae Reason for Inclusion in Manual CAPS Target: AHP Prioritized Pest List - 2010 Pest Description Diabrotica speciosa was first described by Germar in 1824, as Galeruca speciosa. Two subspecies have been described, D. speciosa vigens (Bolivia, Peru and Ecuador), and D. speciosa amabilis (Bolivia, Colombia, Venezuela and Panama). These two subspecies differ mainly in the coloring of the head and elytra (Araujo Marques, 1941; Bechyne and Bechyne, 1962). Eggs: Eggs are ovoid, about 0.74 x 0.36 mm, clear white to pale yellow. They exhibit fine reticulation that under the microscope appears like a pattern of polygonal ridges that enclose a variable number of pits (12 to 30) (Krysan, 1986). Eggs are laid in the soil near the base of a host plant in clusters, lightly agglutinated by a colorless secretion. The mandibles and anal plate of the developing larvae can be seen in mature eggs. Larvae: Defago (1991) published a detailed description of the third instar of D. speciosa. First instars are about 1.2 mm long, and mature third instars are about 8.5 mm long. They are subcylindrical; chalky white; head capsule dirty yellow to light brown, epicraneal and frontal sutures lighter, with long light-brown setae; mandibles reddish dark brown; antennae and palpi pale yellow.

  • A Preliminary Annotated Checklist and Evaluation of the Diversity of the Chrysomelidae (Coleoptera) of the Baja California Peninsula, Mexico
    INSECTA MUNDI, Vol. 19, No. 1-2, March-June, 2005 89 A preliminary annotated checklist and evaluation of the diversity of the Chrysomelidae (Coleoptera) of the Baja California peninsula, Mexico Fred G. Andrews California Department of Food and Agriculture Plant Health & Pest Prevention, Analysis & Identification 3294 Meadowview Road Sacramento, California 95832 Arthur J. Gilbert California Department of Food and Agriculture Plant Health & Pest Prevention, Pest Detection/Emergency Projects 2889 N. Larkin #106 Fresno, California 93727 Abstract. A preliminary annotated checklist of the Chrysomelidae of the Baja California peninsula, Mexico is presented based on literature records and the examination of approximately 16,000 chrysomelid specimens. Seven subfamilies and 218 described species have been identified. Ninty-one species are recognized from the Baja California peninsula for the first time. Twenty-nine species are listed as endemic. An additional 128 morphospecies have been identified as undescribed or not yet associated with described species of mainland Mexico or the United States. Adult host plant associations have been identified for approximately 120 species or 35% of the leaf beetle fauna of the region. Each of the 218 described species is associated with the eight plant communities as outlined by Wiggins (1980). Two dominant subfamilies comprise 76% of the leaf beetle fauna: Galerucinae, 87 species (40%) and Cryptocephalinae, 78 species (36%). The following new combinations are proposed: Neolema californica (Heinze, 1927), transferred from Lema Fabricius, 1798; Pseudoluperus histrio (Horn, 1895), transferred from Keitheatus Wilcox, 1965, and Diachus peninsularis (Schaeffer, 1906), transferred from Triachus J.
