Non-parasitic life cycle of the cattle tick Rhipicephalus (Boophilus) microplus in Panicum maximum pastures in northern Argentina por Mastropaolo, Mariano, Mangold, Atilio Jose, Guglielmone, Alberto, Nava, Santiago

“…The biological parameters measured were proportion of females ovipositing, the pre-oviposition period, the proportion of egg clusters hatching, the incubation period of eggs, larval longevity, and the total non-parasitic period (time from the exposure of the female to the date of death of the last larva) (TNPP)). …”

The soil mite Gaeolaelaps (Hypoaspis) aculeifer (Canestrini) (Acari: Laelapidae) as a predator of the invasive citrus mealybug Delottococcus aberiae (De Lotto) (Hemiptera: Pseudoco... por Pérez-Rodríguez, Jésica, Calvo, Javier, Urbaneja, Alberto, Tena, Alejandro

“…The predation, and fecundity of mites over a 14-day period were analyzed when fed on three different diets under laboratory conditions: D. aberiae eggs, first instar nymphs, and without food. Gaeolaelaps aculeifer preyed on D. aberiae and both predation rates and the proportion of females that laid eggs were significantly higher when females preyed on mealybug nymphs than on eggs. …”

Effect of temperature on the life history of Cirrospilus sp. near lyncus (Hymenoptera: Eulophidae), a parasitoid of Phyllocnistis citrella (Lepidoptera: Gracillariidae) por Urbaneja, Alberto, Llácer, Elena, Garrido, Antonio, Jaques, Josep A.

“…Both gross fecundity and host-feeding were highest at 20°C (170.48 eggs and 32.33 hosts). Oviposition rates were optimal at higher temperatures (5.22 eggs per day at 25°C and 4.79 eggs per day at 30°C) and were dependent on female age. …”

Suitability of the tomato borer Tuta absoluta as prey for Macrolophus pygmaeus and Nesidiocoris tenuis por Urbaneja, Alberto, Montón, Helga, Mollá-Hernández, Óscar

“…Both predators preyed actively on T. absoluta eggs and all larval stages, although they preferred first-instar larvae. …”

Inherited sterility in Tuta absoluta (Lepidoptera: Gelechiidae): Pest population suppression and potential for combined use with a generalist predator por Cagnotti, Cynthia Lorena, Andorno, Andrea Veronica, Hernández, Carmen Marcela, Carabajal Paladino, Leonale Suzel, Botto, Eduardo Norberto, López, Silvia Noemi

“…However, the mirid females preyed on significantly more eggs—roughly 20% more—from irradiated females than on eggs from untreated females. …”

Assessment of habitat suitability for the cattle tick Rhipicephalus (Boophilus) microplus in temperate areas por Nava, Santiago, Gamietea, Ignacio José, Morel, Nicolas, Guglielmone, Alberto, Estrada-Peña, Agustín

“…The establishment of permanent populations of R. microplus south of this latitudinal threshold is currently restricted because the low temperatures in autumn and winter inhibit the development of its eggs, but the introduction of cattle infested with R. microplus from early spring to late summer in temperate areas could produce engorged females laying eggs that would originate viable larvae from late spring to winter. …”

Nematode populations affect grapevine seedlings: Understanding the host-parasite interaction is critical for preventing negative effects por Ndifon, E.M.

“…However, above 520 nematode eggs per pot, the performance of the crop (i.e. plant height, number of leaves, number of tendrils) started to decline gradually, culminating in the lowest performance at 4160 nematode eggs/pot. …”

Postteneral Protein Feeding may Improve Biological Control Efficiency of Aphytis lingnanensis and Aphytis melinus por Vanaclocha, Pilar, Papacek, Dan, Verdú, María J., Urbaneja, Alberto

“…For these reasons, this work focuses on the study of providing a protein feed to Aphytis lingnanensis (Compere) and A. melinus DeBach to improve the egg load before their release. The addition of protein to a honey diet during the first 2 d after the adult parasitoid emergence increased the initial egg load in both species of parasitoids by more than five eggs. …”

Studies on the shootborer Hypsipyla grandella (Zeller) (Lepidoptera Pyralidae). V. Observations on a rearing technique and on host selection behavior of adults in captivity por Grijpma, P.

“…A technique for the laboratory rearing of Hypsipyla grandella Zeller and a method for the mass production of the insect's eggs are described. Based on the data observed with two types of diets, one synthetic and one natural, an equation was estimated that governs the pupal stage and emergence as a function of time. …”

Offspring production and self-superparasitism in the solitary ectoparasitoid Spalangia cameroni (Hymenoptera: Pteromalidae) in relation to host abundance por Böckmann, Elias A., Tormos, José, Beitia, Francisco J., Fischer, K.

“…Under high host abundance, lifetime fecundity (number of eggs laid), offspring number, number of pupae parasitized and hosts killed were greater than under low host abundance, whereas the number of eggs per host was lower; and the proportion of hosts that did not produce offspring tended to be lower. …”

The combined use of Bacillus thuringiensis and Nesidiocoris tenuis against the tomato borer Tuta absoluta por Mollá-Hernández, Óscar, González-Cabrera, Joel, Urbaneja, Alberto

“…The predator Nesidiocoris tenuis Reuter (Hemiptera: Miridae) can regulate T. absoluta populations, because it is able to prey efficiently on T. absoluta eggs. Furthermore, previous studies have demonstrated that first-instar larvae of T. absoluta are highly susceptible to Bacillus thuringiensis (Bt) treatments. …”

Morfología y biología de los crisomélidos Diabrotica balteata LeConte y Cerotoma facialis Erickson como plagas del frijol común por González, R, Cardona, C, Schoonhoven, A. van.

“…When fed bean foliage, females lived an average of 37 days (Diabrotica) and 52 days (Cerotoma) In both species the preoviposition period varied from 5 to 12 days. 77he maximum egg production by adult D. balteata that fed on bean leaves was 144 per female; C. facialis females laid up to 532 eggs. …”
