El  picudo del agave Scyphophorus acupunctatus produce una feromona de agregación que atrae ambos sexos. Sin embargo, la respuesta es baja debido a diferentes factores que interfieren, por lo que es necesario un mejor conocimiento de los factores participantes, así mismo, buscar nuevas alternativas de control. En la presente investigación se plantearon los siguientes objetivos: 1) Determinar la participación del sexo, edad y de la estructura genética en la respuesta electrofisiológica y de comportamiento de búsqueda de S. acupunctatus al compuesto principal de su feromona de agregación. 2) Evaluar la eficiencia de la planta de agave tequilero en estado fermentado en el trampeo del picudo e identificar los compuestos volátiles atractivos para este insecto....

Abstract  Background:  Plant-derived compounds are alternatives of synthetic insecticides in sustainable agriculture.  Objective:  This study investigated the phytotoxic effect of higher concentrations (2, 4, 8 and 16%) of four plants extracts (Azadirachta indica, Mentha arvensis, D. stramonium and Citrus limonium) on cotton plants.  Methods:  Each concentration was replicated four times to check the phytotoxic effect (CO2-in, CO2-out, H2O-in, H2O-out and photosynthesis absorption rate (PAR) in randomized complete block design. Data was recorded after 12, 24, 48 and 72 hours of spray with the help of Photosynthetic CL 340 meter.  Results:  The results showed that CO2-in was more affected by the D. stramonium (131.65±0.38) at 8% concentration. The overall...

ABSTRACT The house fly, Musca domestica L. (Diptera: Muscidae), is a major pest of all aspects of life, like the domestic, medical and veterinary and causal agent of several pathogenic diseases. The present study was conducted to evaluate the potential of different insecticide-free baits against house fly by incorporating flower methanol extract of Helianthus annuus (sunflower) and Tegetes erecta (marigold) at 10%, 20% and 30% bait formulation of corn syrup, dried milk and water. However, imidacloprid and thiacloprid (each at 5% concentration) were also included in the study for comparison. Results showed that insecticide baits were superior in causing mortality of adult house fly but dependent upon syrup. Overall, 20% baits of both extracts caused more...
