Life history of the agromyzid fly Liriomyza trifolii on tomato at different temperatures

Abstract

The effects of three constant (15 °C, 20°C and 25 °C) and one alternating (16–22 °C, mean 19.5 °C) temperatures on development, mortality, feeding, fecundity and longevity of Liriomyza trifolii (Burgess) on tomato plants cv. ‘Moneydor’ were examined in the laboratory. Development rates and thresholds for each instar were estimated by means of linear regression. No correlation was found between life history variables and pupal length. Further, data on the biology of L. trifolii are given and discussed. The intrinsic rate of increase, rm, varied from −0.0023 viable female eggs/♀/day at 15 °C to 0.1254 eggs/♀/day at 25 °C and net reproduction from one viable female egg/ ♀ at 15 °C to 26 eggs/ ♀ at 20 °C. Generation time varied from 48 days at 15 °C to 24 days at 25 °C. Ninety % oviposition occurred within the first 115 degree‐days of adult life at both 20 °C and 25 °C. Fecundity and longevity were highly correlated with the number of feeding punctures. The data indicate that tomato is a suitable host plant allowing populations of L. trifolii to increase if temperatures are above 16 °C. RÉSUMÉ Influence de la température sur la biologie de Liriomyza trifolii élevé sur tomates La vitesse de développement, la mortalité, l'alimentation, la fécondité et la longévité de L. trifolii (Burgess) élevés sur plants de tomates du cultivar ‘Moneydor’ ont été examinées au laboratoire sous 3 températures constantes (15 °C, 20 °C et 25 °C) et une thermopériode (16/22 °C, moyenne 19,5 °C). Les taux de développement et les seuils de chaque stade ont été déterminés à partir des droites de régressions. Aucune corrélation n'a été mise en évidence entre ces variables biologiques et la taille des pupes. De plus, certaines données sur la biologie de L. trifolii sont fournies et discutées. Le taux intrinsèque d'accroissement, rm a varié de −0,0023 oeuf viable/femelle/jour à 15 °C à 0,1254 oeuf viable/femelle/jour à 25 °C et la reproduction nette de 1 oeuf femelle viable/femelle à 15 °C à 26 oeufs femelles viables/femelle à 25 °C. La durée d'une génération a varié de 48 jours à 15 °C à 24 j à 25 °C. 90% de la ponte a eu lieu dans les 115 premiers degrés jours de la vie imaginale à 20 et 25 °C. La fécondité et la longévité étaient fortement liées au nombre de piqûres nutritionnelles. Ces résultats montrent que la tomate est un hôte convenable permettant aux populations de L. trifolii de se développer lorsque la température est supérieure à 16 °C.

Life history studies of the leafminer Liriomyza trifolii on susceptible and resistant cultivars of Dendranthema grandiflora

“…Young flies may still be in the preoviposition phase that last for 1 to 2 days, as Minkenberg (1988) showed for L. trifolii on tomato, a non preferred host. This indicates that host plant effect on oviposition was not expressed in the first days after infection with young flies.…”

The influence of food supply on the parasitoid against Plutella xylostella L. (Lepidoptera: Yponomeutidae) on the longevity and fecundity of the pea leafminer, Chromatomyia horticola (Goureau) (Diptera: Agromyzidae)

“…This fact suggests that nutrients in the Komatsuna leaf sap extremely elongate female longevity. Females of C. horticola may need nitrogen-rich leaf sap for survival, as in the case of females of the serpentine leafminer, Liriomyza trifolii (Burgess) (Diptera: Agromyzidae), which require nitrogen-rich leaf sap for survival and reproduction (Minkenberg, 1988;Minkenberg and Ot- tenheim, 1990). The results of long-term experiments showed the total number of feeding punctures to be the same under all feeding conditions (Figs.…”

Thermal requirements and development of the Korean population of the potato leafminer, Liriomyza huidobrensis (Diptera: Agromyzidae)

“…However, the thermal relationships of insects may vary among species, population, developmental stage, and with other ecological factors such as food sources (Aguilera, 1972;Prando and da Cruz, 1986;Van der Linden, 1990;Vercambre and De Crozals, 1993;Macdonald and Walters, 1993;Gilbert and Raworth, 1996;Lanzoni et al, 2002;Bybee et al, 2004). The host plants can affect the relationship between temperature and the development of Liriomyza trifolii (Charlton and Allen, 1981;Parrella et al, 1983;Leibee, 1984;Miller and Isger, 1985;Parrella, 1987;Minkenberg, 1988;Zoebisch et al, 1992;Nadagouda et al, 1997;Lanzoni et al, 2002). However, few studies have examined this type of relationship for L. huidobrensis (Neder de Roman and Arce de Hamity, 1984;Parrella and Bethke, 1984;Prando and da Cruz, 1986;Lanzoni et al, 2002).…”
