Concluding Remarks Acknowledgments Glossary Bibliography Biographical Sketch Summary In this chapter we describe the current state of tropical insect chemical ecology in Latin America with the aim of stimulating the use of this important tool for future generations of technicians and professionals workers in insect pest management. Sex pheromones of tropical insectsUNESCO that have been identified to– date EOLSS are mainly used for detection and population monitoring. Another strategy termed mating disruption, has been used in the control of the tomato pinworm, Keiferia lycopersicella, and the Guatemalan potato moth, Tecia solanivora. Research into other semiochemicals such as kairomones in tropical insects SAMPLErevealed evidence of their presence CHAPTERS in coleopterans. However, additional studies are necessary in order to confirm these laboratory results. In fruit flies, the isolation of potential attractants (kairomone) from Spondias mombin for Anastrepha obliqua was reported recently. The use of semiochemicals to control insect pests is advantageous in that it is safe for humans and the environment. The extensive use of these kinds of technologies could be very important in reducing the use of pesticides with the consequent reduction in the level of contamination caused by these products around the world. -
Leaf Scarring by the Weevils Neochetina Eichhorniae and N
BioControl (2005) 50: 511–524 Ó Springer 2005 Leaf scarring by the weevils Neochetina eichhorniae and N. bruchi enhances infection by the fungus Cercospora piaropi on waterhyacinth, Eichhornia crassipes Patrick J. MORAN USDA-ARS, Beneficial Insects Research Unit, Weslaco, Texas, USAw; e-mail: [email protected] Received 16 January 2004; accepted in revised form 5 October 2004 Abstract. Additive or synergistic effects among introduced and native insect and plant pathogen agents are necessary to achieve biological control of waterhyacinth (Eich- hornia crassipes), a globally damaging aquatic weed. In field plots, plants were infested with waterhyacinth weevils (Neoechetina bruchi and N. eichhorniae) and leaves were scarred by weevil feeding. Subsequent infection by the fungal pathogen Cercospora piaropi caused necrotic lesions to form on leaves. Necrosis development was 7.5- and 10.5-fold greater in plots augmented with both weevils and C. piaropi and weevils alone, respectively, than in plots receiving only C. piaropi. Twenty-four days after weevil infestation, the percentage of laminar area covered by lesions on third-youngest and oldest live leaves was elevated 2.3–2.5-fold in plots augmented with weevils. Scar density and necrosis coverage on young leaf laminae were positively correlated, even though antipathogenic soluble peroxidases were elevated 3-fold in plots augmented with weevils alone or weevils and C. piaropi. Combined weevil and fungal augmentation decreased shoot densities and leaves per plant. In a no-choice bioassay, weevil feeding on oldest but not young leaves was reduced 44% two weeks after C. piaropi inoculation. Protein content and peroxidase activities were elevated 2–6-fold in oldest leaves three weeks after inoculation. -

Este insecto Lepidóptero de la familia Gelechiidae fue encontrado causan- do daños graves a los cultivos de papa (Solanum tuberosum), lo que afectó negativamente la economía local. Aunque este insecto tiene movilidad re- ducida, ha invadido varios países en Centro y Sur América así como las Islas Canarias en España. El daño causado por T. solanivora ha sido detec- tado en tubérculos cosechados en campo y en almacenamiento. El Impacto económico de la plaga en países del área andina es mucho mas serio que en Centro América, principalmente debido a que la papa es un importante alimento básico de las familias y su producción es intensiva.

Feeding by Waterhyacinth Weevils (Neochetina Spp.) (Coleoptera: Curculionidae) in Relation to Site, Plant Biomass, and Biochemical Factors
BIOLOGICAL CONTROLÐWEEDS Feeding by Waterhyacinth Weevils (Neochetina spp.) (Coleoptera: Curculionidae) in Relation to Site, Plant Biomass, and Biochemical Factors PATRICK J. MORAN1 USDAÐARS, BeneÞcial Insects Research Unit, Weslaco, TX 78596 Environ. Entomol. 33(2): 346Ð355 (2004) ABSTRACT Biological control of waterhyacinth [Eichhornia crassipes (Mart.) Solms.] by water- hyacinth weevils [Neochetina bruchi (Hustache)] and [Neochetina eichhorniae (Warner)] varies according to Þeld environment, season, and plant stress levels. Plants at four Þeld sites were sampled to determine if leaf scarring caused by adult weevil feeding was associated with plant biomass, biochemical and population measures, and insect densities. Leaf scar densities were consistently higher on plants from two sites at which root and dead plant part biomass were high. Scarring was correlated to root and dead biomass across all sites. Scarring was not associated with weevil densities summed across all life stages or larval gallery density. Soluble protein contents were lower in plants from the two sites with high scarring than at two other sites in Spring 2002, and scarring was negatively correlated to protein content across all sites. Protein was usually highest in immature furled leaves. Activities of soluble peroxidase enzymes were highest in old leaves. Scar densities were not associated with canopy height and shoot density. At one site, high scar densities occurred on plants with small leaf areas, which were likely growing slowly under the inßuence of multiple abiotic and biotic stress factors. Mechanical and natural plant removal and regrowth may have facilitated plant compensation for weevil feeding at the other site with high scarring. Temporally and spatially dynamic physical and biochemical plant traits and growth environments could limit biological control of waterhyacinth. -

Revista Colombiana de Entomología 39 (1): 81-87 (2013) 81 Preferencia alimentaria de Neochetina eichhorniae (Coleoptera: Curculionidae) en plantas acuáticas de diferente valor nutritivo Food preference Neochetina eichhorniae (Coleoptera: Curculionidae) by aquatic plants of different nutritional value FEDRA SOLANGE MARTÍNEZ1,2, M. CELESTE FRANCESCHINI1,3 y ALICIA POI1,3 Resumen: Neochetina eichhorniae (Coleoptera: Curculionidae) es un herbívoro asociado a los camalotales de Ei- chhornia crassipes y E. azurea de áreas nativas. Los objetivos de este trabajo fueron: (1) evaluar la preferencia ali- mentaria de los adultos de N. eichhorniae bajo condiciones naturales, utilizando especies de macrófitas nativas que coexisten con las dos plantas huéspedes y (2) analizar la preferencia alimentaria en relación con el contenido de nitró- geno, fósforo y lignina, como indicadores del valor nutritivo de las hojas. Las especies de plantas estudiadas fueron: E. crassipes, E. azurea, Oxycaryum cubense, Thalia multiflora, Salvinia biloba, Pistia stratiotes, Ludwigia peploides y Nymphaea prolifera. Se realizaron pruebas de preferencia de opción doble y múltiple, utilizando raciones de las macrófitas, en presencia y ausencia de las plantas huéspedes. Se cuantificó, respectivamente, el área total dañada por macrófita y por curculiónido y se correlacionó con el valor nutritivo de las hojas. Las plantas huéspedes, cuya superficie dañada varió entre 115 y 284,76 mm2, fueron las especies preferidas. La superficie dañada tuvo correlación positiva con el contenido de nitrógeno de las hojas de las distintas especies de plantas. El contenido de fósforo, lignina y el cociente L: N no tuvieron relación con la preferencia. Neochetina eichhorniae tuvo especificidad por ambas plantas huéspedes, cuyas hojas tuvieron alto contenido de nitrógeno. -
Guatemalan Potato Moth
Rhode Island Department of Environmental Management/Division of Agriculture Guatemalan Potato Moth Tecia solanivora_________________________________________________________________ The Potato moth is most likely indigenous to Guatemala but it has extended its range through Central and South America and Mexico. It can potentially spread internationally through potato shipping which carries the eggs, larvae, and pupae. Spreading may also occur though shipping egg and pupae infested soil, potato plants, reused potato bags, and illegal potato shipping. This pest is able to adapt to different climate zones from subtropical to mildly colder zones where the plant hardiness zone is 7‐13. Adult T. solanivora, photo by Chemtica Description: Eggs are white and are usually found near the base of the plant, uncovered tubers, and occasionally on foliage. Larvae hatch with a transparent‐white color which then turns to a cream color with darker brown spots, then a yellow‐green with darker spots. They burrow into tubers where they feed and grow. When Tuber damage by Tecia solanivora larvae, photo by Cornell University they are ready to pupate, they exit the potato into the soil, close to the surface, where they Damage: form a cocoon of silk and other material. In This pest is considered to be one of the most serious storage facilities, they can make cocoons and destructive pests of potatoes. The larvae feed anywhere (e.g. walls, potato sack, etc.). Adults throughout the potato producing holes (galleries) that are nocturnal and fly short distances while collect residues of food, waste (frass), and shed skin staying close to the ground. They are small and which contaminates the potato. -
Biological Control of Water Hyacinth with Arthropods: a Review to 2000
Biological Control of Water Hyacinth with Arthropods: a Review to 2000 M.H. Julien* Abstract Water hyacinth, native to the Amazon River, invaded the tropical world over the last century and has become an extremely serious weed. The search for biological control agents began in the early 1960s and continues today. Six arthropod species have been released around the world. They are: two weevils, Neochetina bruchi and N. eichhorniae; two moths, Niphograpta albiguttalis and Xubida infusellus; a mite Orthogalumna terebrantis; and a bug Eccritotarsus catarinensis. The mite and X. infusellus have not contributed to control and the bug is under evaluation following recent releases in Africa. The two weevils and the moth N. albiguttalis have been released in numerous infestations since the 1970s and have contributed to successful control of the weed in many locations. It is timely to assess their impact on water hyacinth and, to help in planning future strategies, to identify the factors that contribute to or mitigate against successful biological control. Although the search for new agents continues, and as a result biological control will likely be improved, this technique alone is unlikely to be successful in all of the weed’s habitats. It is important that whole-of-catchment management strategies be developed that integrate biological control with other control techniques. The aims of such strategies should be to achieve the best possible control using methods that are affordable and sustainable; hence the need to develop strategies using biological control as the base component. WATER hyacinth apparently became a problem in the sation of the weed for commercial and subsistence USA following its distribution to participants in the purposes has also been widely considered.
