Both Volatiles and Cuticular Plant Compounds Determine Oviposition of the Willow Sawfly Nematus oligospilus on Leaves of Salix spp. (Salicaceae)
(Springer, 2015-11)Plant volatile organic compounds play a role in selection of host plants by herbivorous insects. Once the insect reaches the plant, contact cues determine host acceptance. Although the willow sawfly Nematus oligospilus ... -
Comportamiento de oviposición de la avispa sierra del sauce Nematus oligospilus (Hymenoptera: Tenthredinidae): el rol de los semioquímicos en la elección de plantas hospederas
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2017-11)Nematus oligospilus representa una amenaza para el cultivo de sauce debido a la intensa defoliación que generan sus larvas. La colonización de las plantas hospederas se inicia cuando las hembras colocan sus huevos en las ... -
Contribución al estudio de la ecología y biología de Epicauta atomaria (Coleoptera: Meloidae), insecto asociado a cultivos agrícolas en América del Sur
(Ediciones INTA, 2021-12)Epicauta atomaria (Meloinae: Epicautini) es un meloideo que pertenece al grupo de especies Epicauta maculata. Es nativo de América del Sur con un rango de distribución muy amplio que va desde los 15° N, en el centro de ... -
¿Cómo diferenciar una gallina que está poniendo de otra que no?
(EEA Santa Cruz, INTA, 2021-06-03)El objetivo de este díptico es facilitar la identificación a simple vista, a través del método de despigmentación y de Hogan, de gallinas que comenzaron la postura de aquellas que no están poniendo huevos o interrumpieron ... -
Cricket oviposition trace fossils in palaeosols and their stratigraphic significance : the South American Palaeosol Ichnofossil Ages (SAPIAs)
(2017-09)The first insect trace fossil in palaeosols attributed to the oviposition of crickets is represented by openings composed of two to four, but usually three, perforations with a tripartite pattern. This pattern is compatible ... -
Cryptic genetic structure in an Argentinian population of Anastrepha fraterculus (Diptera: Tephritidae) evidenced by SSR markers and quantitative traits
(Czech Academy of Sciences, 2019-04)In some regions of Argentina and Brazil, the South American fruit fly Anastrepha fraterculus (Wied.) (Diptera: Tephritidae) causes significant damage to crops. An efficient integrated management program requires knowledge ... -
Evaluación de la oviposición de Goniozus legneri Gordh (Hymenoptera: Bethylidae) sobre distintos lepidópteros de interés frutihortícola
(Fundación Miguel Lillo, 2018)Goniozus legneri (Hymenoptera: Bethylidae) es un parasitoide de lepidópteros. El objetivo de este trabajo fue evaluar su oviposición sobre Cydia molesta, Cydia pomonella, Plodia interpunnctella, Spodopterafrugiperda, Lobesia ... -
Host selection, oviposition behaviour and leaf traits in a specialist willow sawfly on species of Salix (Salicaceae)
(Wiley, 2013-12)Plant genotype influences plant–herbivore interactions by affecting insect attraction, acceptance and development. Here we linked oviposition behaviour of the specialist willow sawfly Nematus oligospilus Förster (Hymenoptera: ... -
Mating-induced changes in responses of female Queensland fruit fly to male pheromones and fruit : a mechanism for mating-induced sexual inhibition
(Elsevier, 2021-03)In order to reproduce, female tephritid fruit flies need both mates for fertilization and fruit for oviposition. Virgin females are prone to mating and approach males, attracted by their pheromones. Mated females, however, ... -
Oviposition and olfactometry response of codling moth (Cydia pomonella) to quince (Cydonia oblonga) cultivars
(Wiley, 2023-03)Quince (Cydonia oblonga Miller) is one of the common hosts of the codling moth, Cydia pomonella L. Knowledge of the chemical ecology of codling moth is based on its behaviour against apples and pears but not quince. Here, ... -
Oviposition substrate location by the invasive woodwasp Sirex noctilio: the combined effect of chemical cues emitted by its obligate symbiont Amylostereum areolatum and different host-tree species
(Wiley, 2023-06)BACKGROUND: Sirex noctilio is an invasive forest wasp that affects pines and can result in severe economic losses. The use of semiochemicals offers an opportunity to develop sensitive and specific capturing systems to ... -
Patterns of resource distribution among conspecific larvae in two fruit fly species : Anastrepha fraterculus and Ceratitis capitata (diptera: tephritidae)
(2016)1 Anastrepha fraterculus (Diptera: Tephritidae) and Ceratitis capitata (Diptera: Tephritidae) are fruit fly pests whose larvae are frequently found sharing the same fruit with conspecifics. Because larvae are incapable of ... -
The use of Leaf Surface Contact Cues During Oviposition Explains Field Preferences in the Willow Sawfly Nematus Oligospilus
(Nature Research, 2019-03-20)After an insect herbivore has reached its host plant, contact cues from the leaf surface often determine host acceptance. We studied contact cues during oviposition behavior of a willow pest, the sawfly Nematus oligospilus ...
