'Ataulfo' mango (Mangifera indica L.) is the most popular cultivar of mango to have originated in Mexico. Because of its relatively recent discovery, few studies have been carried out on the best agricultural practices for production of this cultivar, and there is wide variation in methods among growers. Among other ...

The corn leafhopper Dalbulus maidis (Delong & Wolcott) (Hemiptera: Cicadellidae) originated in Mexico, but is found from southeastern and southwestern USA to Argentina. Differences in reproductive and phenotypic traits between Mexican (native) and Argentinian (adventive) populations have been previously reported, but information on their genetic variation is currently unavailable. The ...

Blackbirds are important agricultural pests that can cause major economic losses in a variety of crops. Although birds in other agro-ecosystems may perform biological control services by controlling insect pests, the potential of blackbirds to provide these services in rice had not been evaluated. We used bird exclosures to evaluate ...

Since it was first formally recorded there in 2005, the Nearctic pine tortoise scale Toumeyella parvicornis (Cockerell) (Hemiptera: Coccidae) has caused severe decline of the Caribbean pine, Pinus caribaea var. bahamensis (Grisebach) W. H. Barrett & Golfari, in the pine forests on the Turks and Caicos Islands (TCI). The scale ...
Moya-Raygoza, Gustavo - - 2012
The corn leafhopper, Dalbulus maidis (DeLong & Wolcott), is one of the most important pests of maize in Latin America because of its efficiency as a vector of 3 species of plant pathogens. In spite of its significance, however, little is known about its egg parasitoids. In this study, we ...
Van Nieuwenhove, Guido - - 2012
Diachasmimorpha longicaudata (Ashmead) is a larval-prepupal endoparasitoid of tephritid fruit fly pests in tropical and subtropical countries. Because citrus-growing areas of northern Argentina are the most affected by Anastrepha fraterculus (Wiedemann), D. longicaudata presents as a potential candidate for augmentative releases against it. Within this context, parasitoid rearing must be ...
Mann, R.S. - - 2012
Biotype B of the sweetpotato whitefly, Bemisia tabaci (Gennadius), is a worldwide pest of many agronomic and horticultural crops, including tomato. Extensive pesticide use targeting this pest has led to the development of resistance to every major class of insecticides. The baseline toxicity of spiromesifen was established for laboratory susceptible ...
Aristizabal, Luis - - 2012
The pink hibiscus mealybug, Maconellicoccus hirsutus Green, is a widespread invasive pest of Hibiscus rosa-sinensis in Florida and elsewhere. We evaluated 3 cultivars of H. rosa-sinensis expected to have high ('President'), low ('Double Red'), and intermediate ('Joanne') levels of susceptibility to this pest. We found little evidence that M. hirsutus ...

The objective of this research was to describe the anal plates of the larval stages of the ephydrid fly, Hydrellia pakistanae Deonier, a biological control agent of hydrilla (Hydrilla verticillata (L.f.) Royle). This was accomplished using light microscopy coupled with a specialized staining technique; and scanning electron microscopy (SEM). All ...

The western drywood termite, Incisitermes minor (Hagen) and the light southern drywood termite I. snyderi (Light) are common drywood termites in southwestern and the southern United States, respectively. Despite the economic importance of these 2 species, no information exists on the mitochondrial genetic diversity of I. minor and I. snyderi. ...

Mole crickets (Orthoptera: Gryllotalpidae) are among the most economically important turfgrass insect pests in the southeastern United States. The tawny mole cricket Scapteriscus vicinus (Scudder) causes damage by feeding on the roots and shoots of turfgrass and by creating surface tunnels. Previous research on mole cricket control showed behavior modification, ...

The parasitoid fly Ormia ochracea acoustically stalks signaling male field crickets and lays live larvae on and around them. Ormia ochracea have been observed to acoustically stalk various cricket species. In Texas the natural host of this fly is Gryllus texensis (Orthoptera: Gryllidae). Two larger potential gryllid hosts, Gryllus assimilis ...

Efforts to monitor and detect tephritid fruit flies in the genus Anastrepha currently involve MultiLure traps baited with two food-based synthetic attractants, ammonia (typically formulated as ammonium acetate or ammonium bicarbonate) and putrescine (1,4-diaminobutane). These baits are used in Central America, Florida, Texas, and the Caribbean to target/ capture economically ...

This study tested the sensitivity of the tupelo leafminer, Antispila nysaefoliella, to vibrational cues and whether their unique behaviors, first reported by Low (2008), may be elicited by the frequencies matching those of parasitic wasps. In the tick behavior, a larva ticks its abdomen back and forth rhythmically, and in ...
