Sex, life history and morphology drive individual variation in flight performance of an insect parasitoid by Fischbein, Deborah, Villacide, Jose Maria, De La Vega, Gerardo, Corley, Juan Carlos

“…The aims of this study were to examine interindividual and sex differences in flight performance and flight characteristics, using a flight mill bioassay, in Megarhyssa nortoni (Hymenoptera; Ichneumonidae), a parasitoid of the invasive woodwasp Sirex noctilio (Hymenoptera: Siricidae), one of the most important pests of pine afforestation worldwide. We also assessed the influence of morphological traits in combination with sex on flight and explored the cost of flight on longevity and mass loss. 3. …”

Exposure of Nonbreeding Migratory Shorebirds to Cholinesterase Inhibiting Contaminants in the Western Hemisphere by Strum, Khara M., Hooper, Michael J., Johnson, Kevin A., Lanctot, Richard B., Zaccagnini, Maria Elena, Sandercock, Brett K.

“…We compared plasma Cholinesterase activities and body masses of individuals captured at sites with no known sources of organophosphorus or carbamates to those captured in agricultural areas where agrochemicals were recommended for control of crop pests. In South America, plasma acetylcholinesterase and butyrylcholinesterase activity in Buff-breasted Sandpipers was lower at agricultural sites than at reference sites, indicating exposure to organophosphorus and carbamates. …”

Energy reserves of parasitoids depend on honeydew from non-hosts by Tena, Alejandro, Pekas, Apostolos, Wackers, Felix L., Urbaneja, Alberto

“…Adult parasitoids depend on sugar-rich foods such as nectar and honeydew to meet their energy requirements and control insect pests. However, it is poorly known whether parasitoids can detect and feed on honeydew in agroecosystems, where it is the primary carbohydrate source, because this sugar source is less apparent in comparison to nectar and sometimes contains repellent compounds for parasitoids. …”

Effects of Pesticides Used on Citrus Grown in Spain on the Mortality of Ceratitis capitata (Diptera: Tephritidae) Vienna-8 Strain Sterile Males by Juan-Blasco, María, Sabater-Munoz, Beatriz, Argilés, Rafael, Jaques, Josep A., Ortego, Felix, Urbaneja, Alberto

“…Because pesticides are required to maintain populations of some citrus key pests below economic thresholds, there is a need to evaluate the effects of pesticides commonly used in citrus on Vienna-8 males. …”

Natal host and learning as factors in host preference by Spalangia cameroni Perkins (Hymenoptera: Pteromalidae) by Tormos, José, Beitia, Francisco J., Asís, Josep D., De-Pedro, Luis

“…These results indicate that rearing S. cameroni on medfly or house fly pupae seems to have little influence on the later performance of this parasitoid in its subsequent use against populations of both fly pests.…”

Climate change and forest genetic diversity: Implications for sustainable forest management in Europe by Koskela, Jaarko, Buck, A., Teissier du Cros, E., Bioversity International, European Forest Genetic Resources Programme

“…This will alter the environmental conditions to which forest trees in Europe are adapted and expose them to new pests and diseases. Climate change will thus create additional challenges for forest management, with consequent impacts on the economic and social benefits that societies and individuals derive from the forests, and on the biological diversity in forest ecosystems. …”
