Employing evolutionary theory to improve biological pest control: Causes of non-adaptive sex allocation behavior in parasitoid wasps and implications por Beltrá, Aleixandre, Pekas, Apostolos, Soto, Antonia, Tena, Alejandro

“…As predicted by Charnov's host quality model, mothers laid female eggs in hosts above a threshold size. This threshold was absolute, i.e. independent of the host size distribution, independently of the sampling site and date. …”

Efficacy of Bacillus thuringiensis (Berliner) in controlling the tomato borer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) por González-Cabrera, Joel, Mollá-Hernández, Óscar, Montón, Helga, Urbaneja, Alberto

“…Furthermore, the integration of this technology with other biological control methods focused on T. absoluta eggs, such as the use of mirid predators or parasitoids, could reduce the number of B. thuringiensis treatments and the use of chemicals, with the consequent reduction of residues on fruits.…”

Combate del gorgojo del camote (Rhyssomantus sp. Curculionidae) por Viale, Emilio, Thomas, N.F.

“…Experiments were conducted by the Inter-American Institute of Agricultural Sciences on control of a sweet-potato weevil of the genus Rbyssomatus. 1 be females of this insect usually deposit the eggs at the base of the stem of the sweet-potato plant the larvae may destroy this part of the stem as well as the roots If edible toots are formed they frequently are made unmarketable by the weevil damage in the field and in storage. …”

Novel defenses of Protopulvinaria pyriformis (Hemiptera: Coccidea) against its major parasitoid Metaphycus helvolus (Hymenoptera: Encyrtidae): Implications for biological control o... por Tena, Alejandro, Beltrá, Aleixandre, Soto, Antonia

“…Three factors limited its efficacy: (i) the scale frequently thwart parasitoid attack by removing its stylet and wiggling, a unique defense in soft scales, (ii) scale honeydew extended M. helvolus lifespan little more than water, and (iii) P. pyriformis did not encapsulate Metaphycus spp. eggs but immature parasitoids died during their prepupal stage, which may have been caused by laurel plant secondary compounds from laurel. …”

Host quality does not dictate the outcome of intrinsic competition between sympatric parasitoids: effect on their coexistence. por Cebolla, Ruth, Urbaneja, Alberto, Tena, Alejandro, Bru, Pablo

“…Aphytis melinus DeBach laid more eggs (clutch size) and accepted significantly more hosts than A. chrysomphali (Mercet) when they encountered heterospecific parasitized hosts of the third instar (higher quality), whereas there were not significant differences in the second instar. …”

Huéspedes y enemigos naturales de Heliothis spp., en la región algodonera del Departamento del Tolima, Colombia por Hallman, G

“…Six paratites and several predators were found attacking Helicthis Cardiochiles nigriceps Vierick (Hymenoptera: Braconidae) parasitized up to 90 percent of the larvae of H virescens collected from D. tostuosum. Eggs of Heliothis escaped parasitism by Trichogramma pretiosum Riley (Hymenoptera Trichogammatidae) on several hosts because of the presence of sticky trichomes on the plants which trapped the adult parasites.…”

Lethal and sublethal effects of spirotetramat on the mealybug destroyer, Cryptolaemus montrouzieri por Planes, Laura, Catalán, José, Tena, Alejandro, Porcuna Coto, José L., Jaques, Josep A., Izquierdo, J., Urbaneja, Alberto

“…Spirotetramat resulted harmless: (1) when directly applied on larvae and adults of C. montrouzieri, since it did not affect survival, longevity, fecundity, egg hatching, and offspring survival. In contrast, chlorpyriphos was classified as moderately toxic for adults due to its effects on fecundity, egg hatching and offspring survival. …”

Larval morphology of Metaphycus flavus and its role in host attachment and larval cannibalism por Tena, Alejandro, Kapranas, Apostolos, Walker, G. P., García-Marí, Ferran, Luck, Robert F.

“…Under our laboratory conditions (25 +/- 1 degrees C and 14 hours of light followed by 18 +/- 1 degrees C and ten hours of darkness in 50-70% R. H.), M. flavus eggs hatched three days after oviposition. Measurements of the mandibles and tentorium indicate there are four larval instars, and M. flavus reaches the fourth instar by day six post oviposition, and pupates on day eight. …”

Ecobiology of Anaphothrips obscurus, a new dweller of citrus orchards brought in by more sustainable pest management practices por Gómez-Martínez, María A., Aguilar-Fenollosa, Ernestina, Jaques, Josep A., Pina, Tatiana

“…However, A. obscurus zoophagy on T. urticae eggs and the host status of citrus can be discarded. 6 Anaphothrips obscurus can be a prey for Euseius stipulatus, Neoseiulus barkeri and Neoseiulus californicus (three phytoseiids preying on T. urticae), suggesting that apparent competition between A. obscurus and T. urticae could occur in citrus orchards.…”
