Heliothis zea (Boddie) larvae reared on artificial diet were treated with permethrin using a topical or dip bioassay at 3, 5, and 7 days post-hatch. Forty-eight-hour survival and weight gain in survivors, percent pupation, and percent adult eclosion were measured in one experiment. Generally, larval weight gain after 48 hours among survivors decreased with increasing dose. A high proportion of individuals surviving after 48 hours went on to pupate and emerge as adults regardless of dose, age, and reduction in growth at 48 hours post-treatment. In a second experiment, pupal and adult weights and development times of larve and pupae were measured after topical treatment of larvae with permethrin. Pupal weights of survivors decreased with increasing dose in all age classes. Adult weights decreased with increasing dose only in the 7-day-old treatment. Development times were protracted with increasing dose in the 5-day-old and 7-day-old treatments, but not the 3-day-old treatment. In both experiments, smaller larvae were more tolerant of permethrin than larger larvae per unit body weight.

  Los insectos plaga, son una de las principales limitantes en la producción del cultivo de maíz. Por lo cual, provocan daño en el desarrollo de la planta y por ende reducen el rendimiento. El gusano cogollero Spodoptera fugiperda J. E. Smith y Heliothis zea (Boddie), (Lepidoptera: Noctuidae) son las de mayor presencia en el cultivo de maíz. Para el control de estas y otras plagas, el control más usado son los insecticidas químicos; las principales desventajas de su uso han sido la contaminación al ambiente y la resistencia de los insectos plaga, esto ha ocasionado daño en el ambiente y resistencia. Una alternativa es la utilización de microorganismos entomopatógenos, depredadores o parasitoides. Dentro de estos se encuentran hongos entomopatógenos como Metarhizum anisopliae (Metchnikoff) Sorokin, y depredadores de la familia Coccinellidae como Cycloneda sangunea (Linnaeus), siendo estas más utilizadas en el control biológico. Asimismo, algunos parasitoides como Telenomus remus (Nixon) (Hymenoptera: Platygastridae). Por lo cual, las ventajas del control biológico es reducir niveles de infestación de plagas a una proporción que no causen daño económico, disminuir el espectro de acción y además no generan contaminación al ambiente. El control biológico depende en gran medida de las condiciones climáticas, etapa fenológica del cultivo y de la interacción entre las plagas y el hospedero.

Colonial Hydroid

The colonial hydroid Cordylophora is a carnivore whose feeding is induced by substances released from captured prey. An active molecule, probably the only one, has been isolated from a fraction of the laboratory food of Cordylophora, brine shrimp larvae, and identified on paper chromatograms as the imino acid proline. Reagent proline induces the feeding reaction at 10-5 M. The reaction is specific in that only two α-imino acids very closely related to proline were found to possess significant activity: azetidine-2-carboxylic acid and pipecolic acid. The response to proline is inhibited by magnesium ions and enhanced by phosphate. Since previous studies have shown that the feeding reactions of Hydra, Physalia, and Campanularia are controlled by reduced glutathione, the phylogenetic implications of the proline control of feeding in Cordylophora are discussed. The feeding reactions of both Cordylophora and Hydra are also induced by proteases, suggesting similar mechanisms of induction in the two hydroids.
