“…The eggs laid were set in glass vials in the chamber described above and hatching occurred at ~5 d. The emerging larvae were immediately fed with fresh alfalfa sprouts until they grew to the 2 nd stadium, when they were fed with fresh corn grains until they were used in the tests. When they reached the 3 rd larval stage, ~15 cm long and 7 d after hatching (Zúñiga et al, 2011), they were fasted 6 h before submitting them to the corresponding treatments to homogenize feeding.…”

La alta presión de infestación de Helicoverpa zea (Boddie) en maíz (Zea mays L.) en Ecuador llevó a evaluar el efecto antialimentario y la mortalidad en laboratorio de larvas de tercer estadío expuestas a extractos en agua de hojas de Schinus molle (L.) y Artemisia absinthium (L.), al 100 y 50% de las concentraciones máximas obtenidas, puros y en mezcla con Bacillus thuringiensis (Berliner) var. kurstaki (Btk). Estos tratamientos se aplicaron también en un ensayo de campo. En el laboratorio, el extracto de S. molle tuvo efecto antialimentario medio (45 a 49%), mientras que el de A. absinthium no tuvo efecto. A 15 días después de la aplicación (DDA), los extractos puros o en mezcla con Btk causaron mortalidad baja (S. molle: 20 a 28%; A. absinthium: 24 a 40%; y en mezcla con Btk 33 y 28%, respectivamente). En esa evaluación, la mezcla de los extractos de S. molle y A. absinthium con Btk no aumentaron el efecto de la bacteria en las larvas. El extracto en agua de S. molle puro o en mezcla con Btk disminuyeron significativamente (P ≤ 0,05) el número de larvas a la cosecha, pero el daño causado por las larvas supervivientes no difirió de aquel en el control no tratado. Los efectos insecticidas obtenidos aumentan las alternativas de control de esta importante plaga en maíz. Palabras clave: Efecto antialimentario, efecto insecticida, extractos de plantas, gusano del choclo, Helicoverpa zea, Zea mays.

Allele frequency of the resistance of the gene Onb3GalT5 to Cry proteins was analyzed in insect populations (Helicoverpa zea and Heliothis virescens), collected from maize transgenic and non-transgenic plants. The genetic parameters estimated in these populations were allele and genotype frequency, genetic balance and Wright statistics (Fis, Fit and Fst). Statistical analyses were performed using the package Genepop (4.0.10). Results showed that from the DNA of H. virescens, collected on non-transgenic maize, a higher number of bands were amplified in a range from 250 bp to 600 bp. In contrast, the bands amplified from insects collected on transgenic maize were in the range of 250 bp-500 bp, being the 400 bp band in both cases the most frequent, while in the DNA of Helicoverpa zea, collected on transgenic maize, three bands (350 bp, 400 bp and 450 bp) were amplified, and in H. zea, collected on non-transgenic maize, only two bands (350 bp and 400 bp) were observed. Genetic diversity in insect populations was higher than within these same populations.
