Potential of Detection and Identification of Nymphal Parasitoids (Hymenoptera: Braconidae) of Lygus Bugs (Heteroptera: Miridae) by Using Polymerase Chain Reaction and ITS2 Sequence Analysis Techniques
Ribosomal ITS2 DNA fragments were sequenced from four Peristenus species, two Leiophron species, and two Lygus species to determine whether LyGus hesperus Knight and LygUS lineolaris (Palisot de Beauvois) were parasitized by Peristinus and Leiophrons parasitoids.
Review of Gonatocerus (Hymenoptera: Mymaridae) in the Neotropical region, with description of eleven new species
The described Neotropical species of the common and speciose fairyfly genus Gonatocerus Nees ab Esenbeck are reviewed and re-diagnosed and seven new synonymies are proposed.
BIOLOGY OF ZAGELLA DELICATA (HYMENOPTERA: TRICHOGRAMMATIDAE), AN EGG PARASITOID OF THE SHARPSHOOTER TAPAJOSA RUBROMARGINATA (HEMIPTERA: CLYPEORRHYNCHA: CICADELLIDAE) IN ARGENTINA
Field and laboratory data suggest that Z. delicata could be a prospective biological control agent against other, exotic, proconiine sharpshooters including H. coagulata, which is restricted to habitats dominated by grasses.

Investigating field host availability and use across a wide latitudinal range, and performed laboratory studies on insect oviposition preference and larval performance and mitochondrial DNA variation in a phylogeographical framework, revealed three geographic races of A. versicolor with gene flow restriction and recent geographic expansion.
A new Gonatocerus (Hymenoptera: Mymaridae) from Argentina, with taxonomic notes and molecular data on the G. tuberculifemur species complex
A new member of the ater species group of Gonatocerus Nees (Mymaridae), is described from the state of Mendoza, Argentina, supported by molecular data, and by results of reciprocal cross-breeding experiments between most of them.
Two Separate Introductions of Asian Citrus Psyllid Populations Found in the American Continents
The data suggest that two separate introductions or founding events of D. citri occurred in the Americas, one in South America and one in North America, and North America and Hawaii appear to share a similar source of invasion.
BIOLOGY OF GONATOCERUS TUBERCULIFEMUR (HYMENOPTERA: MYMARIDAE), AN EGG PARASITOID OF THE SHARPSHOOTER, TAPAJOSA RUBROMARGINATA (HEMIPTERA: CICADELLIDAE)
Abstract Biological traits of a prospective candidate for biological control of the glassy-winged sharpshooter (GWSS), Homalodisca coagulata (Say) (Hemiptera: Cicadellidae), in the United States are…
DNA barcoding and morphological identification of Argentine species of Apanteles (Hymenoptera : Braconidae), parasitoids of cactus-feeding moths (Lepidoptera : Pyralidae : Phycitinae), with…
A recognition of the new species of Apanteles that attack cactus-feeding phycitine moths from Argentina reveals a narrower host range for the species involved in this system, making it necessary to re-evaluate their potential as biocontrol agents of the prickly pear moth.
Studies on the Biology of Hypogeococcus pungens (sensu stricto) (Hemiptera: Pseudococcidae) in Argentina to Aid the Identification of the Mealybug Pest of Cactaceae in Puerto Rico
It is proposed that the population introduced to Australia is neither Hypogeococcus festerianus Lizer y Trelles nor H. pungens, but an undescribed species with three circuli, and that the HypoGEococcus pest of cacti in Puerto Rico is not H.pungens.
New Records on the Geographical Distribution of South American Sharpshooters (Cicadellidae: Cicadellinae: Proconiini) and their Potential as Vectors of Xylella fastidiosa
Strains of X. fastidiosa cause diseases such as“Pierce’ s Disease” in grape,“Phony Peach Disease’ (PPD), “Coffee Leaf Scorch” (CLS,” “Oleander Leaf Scorched“ (OLS), and“Citrus Variegated Chlorosis”(CVC) among oth-ers.
