Notes On A New Mealybug (Hemiptera: Coccoidea: Pseudococcidae) Pest In Florida And The Caribbean: The Papaya Mealybug, Paracoccus Marginatus Williams And Granara De Willink, Douglass R. Miller, Douglas J. Williams, Avas B. Hamon
Insecta Mundi
Paracoccus marginatus Williams and Granara de Willink, here called the papaya mealybug, was first detected in the United States in Hollywood, Florida in 1998. By the end of 1998 it was found in four localities in the state and has since spread to nine localities in five counties. This mealybug appears to have moved through the Caribbean area since its 1994 detection in the Dominican Republic. The pest is reported to cause serious damage to tropical fruit, especially papaya, and has been detected most frequently, in Florida, on hibiscus. It is now known from Antigua, Belize, the British Virgin Islands, …

Termites Of The Genus Cryptotermes Banks (Isoptera: Kalotermitidae) From The West Indies, Rudolf H. Scheffrahn, Jan Krecek
Insecta Mundi
A taxonomic revision of the genus Cryptotermes occurring in the West Indies is given based on recent collections from the Greater Antilles, Lesser Antilles, and the Bahamas. Seventeen indigenous and four nonindigenous species are described from external morphology of the soldier. The imago caste is also described for all but one species. The indigenous Cryptotermes comprise twelve new species, including C. aequacornis, C. cryptognathus, C. cylindroceps, C. cymatofrons, C. darlingtonae, C. juliani, C. maizgoldi, C. nitens, C. parvifroizs, C. rotundiceps, C. spathifrons, and C. undulans. Five indigenous species are redescribed, including C. cavifrons Banks, C. chasei Scheffrahn, C. …
Distribution And Inhibition Of Esterases In Various Body Tissues Of Susceptible And Resistant German Cockroaches (Dictyoptera: Blattellidae), No-Joong Park, Shripat T. Kamble
Distribution And Inhibition Of Esterases In Various Body Tissues Of Susceptible And Resistant German Cockroaches (Dictyoptera: Blattellidae), No-Joong Park, Shripat T. Kamble
Department of Entomology: Faculty Publications
The distribution and inhibition of esterase activity among body of the resistant Crawford and susceptible CSMA strains of male German cockroach, Blattella germanica (L.), were evaluated with α- and β-naphthyl esters using a spectrophotometric assay and native polyacrylamide gel electrophoresis. The esterase activities in the Crawford strain were significantly higher than in the CSMA strain in most tissues except midgut and male genitalia, where the activities were similar. In both strains, isozyme a was dominant in the brain and fat body and isozymes c and d were more abundant in the midgut; but in addition to isozyme a, isozyme …
