“…Specialized insect herbivores that commit large parts of their life cycles on a given plant species are more likely to evolve sequestration than a generalist that feeds on an array of plant species. Specialist herbivores are known to adapt to secondary compounds and even to use these compounds as stimulants in their diet (Renwick & Lopez, 1999;Roessingh et al, 2000;Stadler, 2000). Additional studies are needed to demonstrate sequestration of eucalyptus compounds by T. arnobia larvae, to confirm that these compounds indeed provide self-defense against predation, and to investigate whether these plant compounds are also used as phagostimulants by T. arnobia.…”

Many herbivorous insects can overcome chemical plant defenses, using the plant's defensive products for their own good, as a defense against predators. Eucalyptus spp. (Myrtaceae), recently introduced in Brazil, are rich in secondary compounds; however, there are reports that these plants have been suffering from population outbreaks of defoliating Lepidoptera in Brazil. The predator Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae) has been used against herbivorous insects in eucalyptus plantations, but little is known about its establishment in the field. This study aims to investigate whether the effectiveness of this predator may be affected indirectly by compounds of eucalyptus plants, when compared to guava, Psidium guajava L., a Brazilian native species of Myrtaceae. Thus, we evaluated the performance of P. nigrispinus on larvae of Thyrinteina arnobia (Stoll) (Lepidoptera: Geometridae) reared on eucalyptus (exotic species) or guava plants (native species). Podisus nigrispinus performance (reproduction and survival) was better on larvae fed on guava than on larvae fed on eucalyptus. It is possible that the negative effect on the predator's development occurred because of the plants’ secondary compounds appropriated by caterpillars, due to the short coevolutionary history between eucalyptus and the predator. The data suggest that the chemical compounds that could help the plant's defenses against herbivores may also affect their natural enemies, especially when the interaction between plant and natural enemy involves an exotic plant recently introduced into the insect's habitat.

“…De acordo com Dobler (2001), uma óbvia pré-condição para o seqüestro de compostos secundários de plantas está na freqüência com que determinado herbívoro se alimenta da planta, pois insetos herbívoros especializados em uma determinada espécie de planta são mais passíveis de seqüestrarem compostos que insetos herbívoros generalistas. Segundo Renwick;Lopez (1999), Roessingh et al (2000) e Stadler (2000), os insetos herbívoros especialistas são conhecidos por exibirem adaptações aos compostos secundários e até mesmo por utilizarem esses compostos como estimulantes na sua alimentação.…”

ResumoO gênero Eucalyptus abrange as espécies arbóreas mais utilizadas para reflorestamento no Brasil. Devido ao seu elevado conteúdo de substâncias secundárias, esperava-se que os insetos não causassem sérios danos ao eucalipto. Contudo, muitos insetos, principalmente os da ordem Lepidoptera, tornaram-se sérias pragas na eucaliptocultura. O predador Podisus nigrispinus Dallas (Heteroptera: Pentatomidae) vem sendo utilizado contra insetos herbívoros tais como Thyrinteina arnobia Stoll (Lepidoptera: Geometridae), principal praga do eucalipto, mas não se têm dados sobre seu estabelecimento em áreas de eucalipto. Dessa forma, o objetivo deste trabalho foi avaliar o potencial reprodutivo e sobrevivência de P. nigrispinus sobre T. arnobia proveniente de eucalipto e larvas de Tenebrio molitor L. (Coleoptera: Tenebrionidae) provenientes de criação massal em laboratório. Os aspectos biológicos de P. nigrispinus foram melhores sobre pupas de T. molitor em comparação aos indivíduos criados sobre lagartas de T. arnobia. Provavelmente, as lagartas de T. arnobia estão seqüestrando as substâncias secundárias das plantas de eucalipto e utilizando em sua defesa contra predadores como P. Nigrispinus, e se estes inimigos naturais não estiverem adaptados a tais compostos, a sua performance no controle da praga e no seu próprio desenvolvimento podem ser afetados negativamente. Palavras-chave: Predador; controle biológico; Eucalyptus; herbívoro. Abstract Biological aspects of Podisus nigrispinus Dallas (Heteroptera: pentatomidae) on Thyrinteina arnobia stoll (Lepidoptera: geometridae) and Tenebrio molitor L. (Coleoptera: tenebrionidae). The genusEucalyptus contains the arboreal species most used to reforestation in the Brazil. Like the plants of this genus presents elevated content of secundarity substances, was waited that they might not cause serious damages to the eucalyptus. However, many insects, principally those of the order Lepidoptera, becomes serious pests in the culture of eucalyptus. The predator Podisus nigrispinus Dallas (Heteroptera: Pentatomidae) has been used against herbivorous insects like Thyrinteina arnobia Stoll (Lepidoptera: Geometridae), but there is not data about your establishment in eucalyptus areas. The objective of this work was evaluate the reproductive potential and to perform a analyses of survival of P. nigrispinus on T. arnobia proceeding of eucalyptus and grub Tenebrio molitor L. (Coleoptera: Tenebrionidae) proceeding of mass rearing in laboratory. The biologics aspects of P. nigrispinus were better on pupa of T. molitor when compared the individuals create on caterpillar of T. arnobia. Probably, the caterpillar of T. arnobia are kidnapped the secundarity substances from the Eucalyptus plants and using for your defense against predators like P. nigrispinus and, if these naturals enemies are not adapted to these substances, their performance in the pest control and on their own development may be negatively affected.

“…These metabolites could allow C. pomonella to discriminate between host plant species by the presence of sorbitol, which characterises ligneous Rosaceae, and the difference in metabolite ratio could explain the different stimulatory effect of leaves and apples. Surface metabo- lites have already been shown to be egg-laying stimulants in other insects: myo-inositol in a citrus-feeding species, Papilio protenor (Honda, 1990), dulcitol (stereo-isomer of sorbitol) in Y. cagnagellus feeding on Euonymus europaeus (Roessingh et al, 2000), and fructose in Ostrinia nubilalis Hbn. This type of resistance would be rather interesting to investigate owing to some advantages compared to antibiosis like less selective pressure, better yield, and few modifications of gustatory quality of the product.…”

Water soluble metabolites identified from surfaces of apple tree fruit and leaf stimulate oviposition in Cydia pomonella L. The effects of two artificial blends of primary metabolites representing fruit and leaf surfaces, respectively, and of components within the blends were examined on egg-laying after two time periods: 3 min and 25 min of darkness. An artificial mixture of six metabolites, viz., three sugar alcohols (sorbitol, quebrachitol, and myo-inositol) and three sugars (glucose, fructose, and sucrose) did stimulate egg-laying. Fructose, sorbitol, and myo-inositol are important components of the stimulatory blend. Contact durations may induce variations in egg-laying responses. After 3 min of darkness, there were no differences in numbers of females laying eggs nor in the numbers of eggs laid on cloths treated with the complete blends and the controls. There were, however, clear effects of groups of compounds and of individual compounds. Reduced blends without sugars and sugar alcohols were in many cases significantly less stimulatory than the complete blends and the controls. After 25 min of darkness, the proportions of females laying eggs as well as the numbers of eggs were higher after treatment with the complete blends than on the controls. The proportions of females laying eggs on cloths treated with the reduced blends were rather similar to the controls, whereas there were still significant effects on the numbers of eggs laid after treatment with reduced blends derived from fruits but not from leaves.
