“…Bemisia brassicae population tended to decrease while that of B. tabaci and T. tabaci populations tended to increase as the median temperature increased. Increases in temperature favor B. tabaci and T. tabaci populations while heavy rain and high humidity are deleterious to these insects (Horowitz, 1986;Lorini & Dezordi, 1990;Horowitz et al, 1994;Gonçalves, 1997;Leite et al, 2002a). On the other hand, high temperatures and rainfall are important mortality factors of aphids in field (Nakata, 1995;Cividanes, 2002;Cividanes & Santos, 2003).…”

“…Several factors such as climatic conditions, crop fertility status, natural enemies, and leaf organic compounds can influence insect population on plants (Horowitz, 1986;Leite et al, 1996;Gonçalves, 1997;Eigenbrode & Pillai, 1998;Hooks et al, 1998). However, these factors have been little studied in kale.…”

“…Considerando a população de tripes como um todo (ninfas + adultos) e o ciclo completo da cultura, os materiais mais atacados foram "CNPH 6244", "BRS Cascata", "Valencianita" x "Aurora", "Primavera" x "Pera Norte", "Pera Norte" x "Primavera", "Belém IPA 9", "CNPH 6400 Chata", "CNPH 6400 Redonda", "Crioula Alto Vale" e "1015 Y" (3,54 insetos/folha). Gonçalves et al (1997) Tabela 1. Número de ninfas, de adultos e total de tripes/folha, queima-das-pontas, mal-das-sete-voltas e mancha-de-alternária em oito populações e oito variedades de cebola (Number of nymphs, of adults and total number of trips/leaf, tip-burn, seven curls and purple blotch of eight populations and eight varieties of onion).…”

“…Provavelmente esse fato se deva ao aumento de temperatura média do ar e redução da umidade relativa do ar, já que as mesmas correlacionaram significativamente com a população de tripes (r = 0,92 e r = -0,90 respectivamente). Lall & Singh (1968), Gonçalves et al (1997) e Leite et al (2004) relataram que o aumento da temperatura e a queda da umidade relativa do ar favoreceram T. tabaci em cebola. Por sua vez, irrigações constantes, como do presente trabalho, apresentam efeito adverso a esta praga (Kannan & Mohamed, 2001).…”

“…High temperatures and rainfall usualy are important mortality causes of aphids in the field (Walker et al, 1984;Nakata, 1995;Picanço et al, 1997) and this factor can also regulate populations of thrips, because the rain washes nymphs and adults of this pest from eggplant leaves (Etienne et al, 1990;Kajita et al, 1996). On the other hand, temperature increase favours populations of thrips, reducing developmental period (Lorini and Dezordi, 1990;Gonçalves, 1997). A possible explanation for the higher number of aphids in eggplant plantations of Viçosa was the presence of higher number of aphid parasitoids as Adialytus, ladybugs and Neuroptera species than in Guidoval.…”
