“…The age of the H. armigera host egg did not affect survival rate (emergence rate) of T. euproctidis offspring. Similar results were also reported for Trichogramma chilonis Ishii emerging from Plutella xylostella (L.) [42], Trichogramma cacoeciae Marchal, Trichogramma principium Sugonjaev & Sorokina, and Trichogramma evanescens Westwood from Phythorimaea operculella (Zeller) [43], T. cacoeciae from Lobesia botrana Denis and Schiffermuller [15], T. pretiosum from Mocis latipes (Guenee) [44], and Trichogramma galloi Zucchi from Diatraea saccharalis (F.) [45]. However, T. evanescens offspring survival rate declined as E. kuehniella egg age increased.…”

The noctuid Helicoverpa armigera is an economically important pest of agricultural crops in Iran and other countries. Research is evaluating the capacity of Trichogramma parasitoids to control H. armigera populations on field crops. The objective of this research was to determine if young rather than old H. armigera eggs were optimal for Trichogramma euproctidis development, reproduction, and life table parameters. Bioassays involved exposing T. euproctidis mated females to H. armigera 14, 38, or 62 h old eggs within 24 h in laboratory arenas. Results indicated that the number of host eggs parasitized successfully by T. euproctidis decreased as host egg age increased. Host egg age had no significant effect on T. euproctidis adult emergence. Adults that developed in 14 h old eggs had greater longevity and fecundity than those that developed in 38 h or 62 h old eggs. The intrinsic rate of increase (r) was greatest, and the mean generation time (T) was lowest for T. euproctidis reared in 14 h old eggs. This study indicates that young H. armigera eggs are more suitable than old ones for T. euproctidis development and reproduction. This study is important because it provides evidence, for the first time, that T. euproctidis can utilize H. armigera as a rearing host. Using young rather than old host eggs could ensure the persistence of a T. euproctidis mass production system to support augmentative releases.

“…Segundo Jacob et al (2006), em algumas espécies ovos mais velhos não apresentam efeito deletério no sucesso de parasitismo. Stinguel et al (2013) também constataram sucesso de parasitismo de 100% em ovos de Mocis latipes Guenée, 1852 (Lepidoptera: Noctuidae) de 24, 48 e 72 horas, parasitados por T. pretiosum. Oliveira et al (2003) registraram 95,5% de sucesso por Trichogramma maxacalii Voegelé & Pointel, 1980 em ovos de um dia de idade de Oxydia vesulia Cramer, 1779 (Lepidoptera: Geometridae), em comparação com os de três e cinco dias.…”

ABSTRACT. Infl uence of host age and learning on chemotactic behavior and parasitism of Trichogramma pretiosum. Trichogramma pretiosum Riley, 1879 reared on Ephestia kuehniella Zeller, 1879 eggs, have been used in biological control of Spodoptera frugiperda (J. E. Smith, 1797). However, host age and experience just after emergence might have some infl uence on parasitism and parasitoid behavior. This study evaluated the infl uence of S. frugiperda host age and egg odor experience, on chemotactic behavior and parasitism of T. pretiosum. Spodoptera frugiperda eggs with 24, 48 and 72 hours were exposed to T. pretiosum females. Parasitoid time experience, in the same host, was evaluated within 1, 3, 4, 5, 6 and 24 hours, as well as, its host exposed time (1, 2, 3 and 24 hours). Chemotactic responses of T. pretiosum (experienced and inexperienced females) to S. frugiperda egg extracts were recorded in Y-tube olfactometer. We also observe parasitism rates (choice tests) in insects with and without experience. The parasitism average was higher in S. frugiperda eggs with 24 hours. Inexperienced females and those experienced for 1, 3 and 4 hours, parasitized less S. frugiperda eggs compared to those for 5, 6 and 24 hours. There was no diff erence in parasitism from females exposed for 2, 3 and 24 hours when compared to those exposed for one hour. Experienced females were more attracted to S. frugiperda eggs odor than to control (hexano). Parasitism percentage, by inexperienced parasitoids, was greater in E. kuehniella eggs (original host) than in S. frugiperda, however it was not observed in experienced females.KEYWORDS: Biological control, egg parasitoid, eggs extract.RESUMO. Trichogramma pretiosum Riley, 1879 mantido em ovos de Ephestia kuehniella Zeller, 1879, tem sido utilizado no controle biológico de Spodoptera frugiperda (J. E. Smith, 1797). No entanto, fatores como idade do hospedeiro e experiência prévia, podem infl uenciar o parasitismo e o comportamento do parasitoide. Esse estudo avaliou a infl uência da idade dos ovos e da experiência em ovos e extrato de ovos de S. frugiperda no comportamento quimiotáxico e no parasitismo de T. pretiosum. Ovos de S. frugiperda com 24, 48 e 72 horas, foram expostos a fêmeas de T. pretiosum. Também foi avaliado o tempo de experiência do parasitoide, no mesmo hospedeiro, por 1, 3, 4, 5, 6 e 24 horas, assim como, seu tempo de exposição (1, 2, 3 e 24 horas). As respostas quimiotáxicas de T. pretiosum (experiente e não experiente) em extrato de ovos de S. frugiperda foram observadas em olfatômetro tipo Y. As taxas de parasitismo foram registradas em teste de escolha, com insetos experientes e inexperientes com ovos e extrato de ovos de S. frugiperda. O parasitismo em S. frugiperda foi signifi cativamente maior em ovos com 24 horas de idade. Fêmeas inexperientes e experientes por 1, 3 e 4 horas, apresentaram uma menor taxa de parasitismo, quando comparadas a fêmeas expostas por 5, 6 e 24 horas. Não houve diferença de parasitismo em fêmeas expostas por 2, 3 e 24 horas, comparadas à...

“…However, it is not consistent, because alterations in physical-chemical characteristics that occur during the embryonic development of the egg, for each host, may or not interfere in the viability of parasitoids in the Trichogramma genus. This fact can be diagnosed in studies by Zuim et al (2013) and Stinguel et al (2013) when working with M. latipes as a host, in which the egg age did not influence on viability of parasitoids T. exiguum and T. pretiosum.…”

“…The non-acceptance of the parasitoid to a particular host is sometimes not exclusive to a single species, or strain, as in the case of T. pretiosum and T. exiguum in eggs of Mocis latipes (Lepidoptera: Noctuidae), in which both species presented reduced rates of parasitism (STINGUEL et al, 2013;ZUIM et al, 2013) and Milanez et al (2009) for several Trichogramma species and strains on T. ni. According to age of the host egg, change in its physical and chemical characteristics is the factor that has been more influential in the development of the parasitoid, as it was demonstrated in this study.…”

Objetivamos avaliar a influência da idade dos ovos de Trichoplusia ni (Lepidoptera: Noctuidae) em fêmeas de Trichogramma pretiosum (Hymenoptera: Trichogrammatidae), em diferentes temperaturas. Assim, ovos de T. ni com idade ≤ 12, ≤ 24, ≤ 36, ≤ 48, ≤ 60 e ≤ 72 horas de desenvolvimento embrionário, separados a temperaturas de 20, 25 e 30 ºC, foram oferecidos para fêmeas de T. pretiosum com até 24 horas de idade. O parasitismo foi inversamente proporcional ao desenvolvimento embrionário do ovo, com maiores taxas de parasitismo observadas para ovos com até 24 horas de desenvolvimento embrionário nas três temperaturas. A viabilidade do parasitismo foi influenciada pela idade dos ovos. Os ovos, com até 36 horas de idade, apresentaram viabilidade superior a 85% nas três temperaturas. A proporção sexual a 25ºC apresentou a melhor taxa dentro da faixa de desenvolvimento embrionário. O número de descendentes do parasitoide por ovo foi influenciado pela temperatura e pela idade dos ovos, sendo a combinação ovos com 60-72 horas à temperatura de 30ºC, a que apresentou o maior quantitativo de descendentes parasitoides por ovo. Esses resultados indicaram que a idade do hospedeiro e a temperatura ambiente podem alterar as características biológicas dos parasitoides.
