Foreign Exploration For Scirtothrips Perseae Nakahara (Thysanoptera: Thripidae) And Associated Natural Enemies On Avocado (Persea Americana Miller), Mark S. Hoddle, Sueo Nakahara, Phil A. Phillips
Foreign Exploration For Scirtothrips Perseae Nakahara (Thysanoptera: Thripidae) And Associated Natural Enemies On Avocado (Persea Americana Miller), Mark S. Hoddle, Sueo Nakahara, Phil A. Phillips
USDA Systematic Entomology Laboratory
Scirtothrips perseae Nakahara was discovered attacking avocados in California,USA, in 1996. Host plant surveys in California indicated that S. perseae has a highly restricted host range with larvae being found only on avocados, while adults were collected from 11 different plant species. As part of a management program for this pest, a ‘‘classical’’ biological control program was initiated and foreign exploration was conducted to delineate the home range of S. perseae, to survey for associated natural enemies and inventory other species of phytophagous thrips on avocados grown in Mexico, Guatemala, Costa Rica, the Dominican Republic, Trinidad, and Brazil. Foreign …

A New Species Of Enaphalodes Haldeman From Florida (Coleoptera: Cerambycidae) With Review Of Genus, Synonymy, And Key To Species, Steven W. Lingafelter, John A. Chemsak
USDA Systematic Entomology Laboratory
A new species of Enaphalodes, E. archboldi Lingafelter and Chemsak, is described from Archbold Research Station, Highlands County, Florida. This localized species has been confused with A. rufulus (Haldeman), a widespread species, which it resembles. Romaleum decipiens Bates is designated as a new synonym of E. atomarius (Drury). Romaleum cylindricum Knull is designated as a new synonym of E. cortiphagus (Craighead). Diagnoses, habitus photographs and drawings, and a key to the nine recognized species of Enaphalodes are provided.

USDA Systematic Entomology Laboratory
Phylloxere notabilis Pergande, 1903, commonly known as the pecan leaf phylloxera, is a pest in the pecan-growing areas of the Southern and Eastern United States and Eastern Europe. Of the four species of Phylloxera known to occur on pecan, P. notebilis is the only species which has more than one generation of galls per year.
One New Species And One New Combination In Netechma Razowski (Lepidoptera: Tortricidae: Euliini), John W. Brown, David Adamski
One New Species And One New Combination In Netechma Razowski (Lepidoptera: Tortricidae: Euliini), John W. Brown, David Adamski
USDA Systematic Entomology Laboratory
Netechma similis, new species, from Costa Rica, is described and illustrated, and Netechma caesiata (Clarke), new combination, from Venezuela, is redescribed and illustrated. Netechma Razowski belongs to a group of genera in Euliini characterized by one or more sparganothine-like features of the male genitalia, including a spiny transtilla; a long, slender, hooklike uncus; and densely scaled socii. Adults of the two treated species are superficially most similar to species of Icteralaria Razowski, with a forewing that features a broad, dark, medial band on a pale yellow ground color.
The Potential For Spread Of Codling Moth (Lepidoptera: Tortricidae) Via Commercial Sweet Cherry Fruit: A Critical Review And Risk Assessment, C. H. Wearing, J. D. Hansen, C. Whyte, C. E. Miller, J. Brown
The Potential For Spread Of Codling Moth (Lepidoptera: Tortricidae) Via Commercial Sweet Cherry Fruit: A Critical Review And Risk Assessment, C. H. Wearing, J. D. Hansen, C. Whyte, C. E. Miller, J. Brown
USDA Systematic Entomology Laboratory
The identity, geographical distribution, and host range of codling moth is reviewed, and the evidence for sweet cherry being a host is critically analyzed. A model is described which assesses the risk of codling moth being spread through international trade in sweet cherries, as exemplified by exports from, respectively, New Zealand and USA to Japan in winter and summer. The model is based on the recorded incidence of codling moth in cherries and its estimated probability of survival during storage, transport to, and arrival in Japan, using data from specific studies and from wider knowledge of the phenology, life history, …

Diagnoses and descriptions are given for the two species, along with scanning electron micrographs of key characters. Modifications are made to a previous key to include these new additions to the eastern …

Rhyparochromus Saturnius (Rossi) (Heteroptera: Lygaeoidea: Rhyparochromidae), A Palearctic Seed Bug Newly Discovered In North America, Thomas J. Henry, David Adamski
Rhyparochromus Saturnius (Rossi) (Heteroptera: Lygaeoidea: Rhyparochromidae), A Palearctic Seed Bug Newly Discovered In North America, Thomas J. Henry, David Adamski
USDA Systematic Entomology Laboratory
The Palearctic rhyparochromid Rhyparochromus saturnius (Rossi) [Lygaeoidea] is reported for the first time in North America based on collections from 17 counties in California. Literature pertaining to this adventive species is reviewed, notes on its habits are given, and descriptions and photographs of the adult and fifth-instar nymph are provided to help distinguish it from other North American Rhyparochromidae. It is speculated that R. saturnius was introduced in international commerceoriginating from the Mediterranean Region, most likely Italy or nearby countries.

A New Species Of Gall Midge (Diptera: Cecidomyiidae) From Subterranean Stem Galls Of Licania Michauxii (Chrysobalanaceae) In Florida, Raymond Gagne, Kenneth Hibbard
A New Species Of Gall Midge (Diptera: Cecidomyiidae) From Subterranean Stem Galls Of Licania Michauxii (Chrysobalanaceae) In Florida, Raymond Gagne, Kenneth Hibbard
USDA Systematic Entomology Laboratory
A new species of gall midge is described from subterranean stem galls on Licania michauxii Prance from Florida. The gall former is a new species of Lopesia and the first record of this genus in North America. The limits of Lopesia, a genus previously recorded only from South America and Africa, are enlarged to accept the new species. The species is described and illustrated. The pupa of this species is unique in Cecidomyiidae for its large, robust, dorsal abdominal spines that may be used in pushing through sandy soil after leaving the gall.
Two New Species Of Lestodiplosini (Diptera: Cecidomyiidae) Preying On Homoptera And Thysanoptera In Southern Florida, Raymond Gagne, Fred Bennett
Two New Species Of Lestodiplosini (Diptera: Cecidomyiidae) Preying On Homoptera And Thysanoptera In Southern Florida, Raymond Gagne, Fred Bennett
USDA Systematic Entomology Laboratory
Two new species of predaceous Lestodiplosini from southern Florida are described and illustrated. Lestodiplosis laticaulis Gagne preys on Diaspis echinocacti (Bouche) (Homoptera: Coccoidea: Diaspididae), and Thripsobremia thripivora Gagne preys on Gynaikothrips ficorum (Marchal) (Thysanoptera: Phlaeothripidae) and Trioza magnoliae (Ashmead) (Homoptera: Psyllidae). The new species are compared to their congeners and the status of Thripsobremia is discussed.

Details of its biology on lime are given, the life stages illustrated, and the three larval instars described in detail.
Native American Plant Hosts Of Asphondylia Websteri (Diptera: Cecidomyiidae), Raymond J. Gagne, William M. Woods
Native American Plant Hosts Of Asphondylia Websteri (Diptera: Cecidomyiidae), Raymond J. Gagne, William M. Woods
USDA Systematic Entomology Laboratory
Asphondylia websteri Felt is reported for the first time from native American hosts, Parkinsonia and jojoba. Previously, this apparently native American gall midge was known only from alfalfa and guar, two species exotic to North America. Such a wide disparity of hosts is otherwise unknown for North American Asphondylia spp. This discovery excludes A. websteri from consideration as a biocontrol agent of Parkinsonia aculeata in Australia.
A Revision Of The Nearctic Species Of The Genus Phronia (Diptera: Mycetophilidae), Raymond Gagne
A Revision Of The Nearctic Species Of The Genus Phronia (Diptera: Mycetophilidae), Raymond Gagne
USDA Systematic Entomology Laboratory
Phronia contains 86 species of small, brown or black mycetophilids. Adults of these fungus gnats are most often caught flying above the forest floor, especially along damp ravines. The fungivorous larvae have been found grazing on slime molds growing on the surface of decaying logs. Most species occur in the Holarctic region, but 1 described and several undescribed species are known from the Ethiopian region. In North America, there are 49 species, 33 of which are known also from Europe.
