“…In Tucumán province the parasitism of D. saccharalis eggs is due to Trichogramma spp. (Hymenoptera: Trichogrammatidae) (Isas et al ., 2016) and its presence period in sugarcane crop does not overlap with burnings.…”

“…The natural enemies of D. saccharalis in Tucumán are several species of Trichogramma genera (eggs parasitoids) (Hymenoptera: Trichogrammatidae), Paratheresia claripalpis (Diptera: Tachinidae), Jayneleskia jaynesi (Diptera: Tachinidae), Agathis sp. (Hymenoptera: Braconidae) and Iphiaulax tucumanus (Hymenoptera: Braconidae) (larval parasitoids) (Box, 1927; Hayward, 1943; Willink et al ., 1991; Pérez et al ., 2010; Isas et al ., 2016).…”

In the American continent, the sugarcane borer Diatraea saccharalis (F.) is the main pest in sugarcane producing areas. The objective of this study was to assess the effect of crop residue management on damage by D. saccharalis, its egg parasitoids and the ants associated with sugarcane. The study was carried out during 2011–2012, 2012–2013 and 2013–2014 crop cycles, in three commercial fields located in different regions of Tucumán state, Argentina. Two types of crop residue management (= treatments) were compared: conservation of trash at the soil surface (CT) and trash burning (TB). In ‘trash conservation’ treatment, crop residue was allowed to remain over the soil surface during the whole sugarcane growing season, while the second treatment consisted of complete burning of trash blanket approximately 2 weeks after harvest. The injury level was measured by recording the number of stalks bored and internodes bored. Parasitism was estimated by counting the total number of eggs and number of black eggs (which indicates the occurrence of egg parasitoids). Ants (Formicidae) richness was calculated by two estimators; abundance-based coverage estimator and incidence-based coverage estimator, using the non-parametric richness estimators: Chao 2 and Jackknife. Finally, the indicator value was estimated through the measurement of specificity and fidelity. In all the parameters studied no significant difference was found between TB and CT treatments.

“…In the present study, after the first three days of parasitism, differences were apparent between the isolines selected in D. saccharalis eggs (ATP-I) and the non-selected strain. This finding suggested that the results could be different if the T. atopovirilia strain assessed was the same collected in Brazil (states of Tocantins and Piauí) or Argentina, where it naturally parasitized D. saccharalis (Silva et al, 2018 unpublished data;Isas et al, 2016) rather than the strain kept at labotratory condition, which was originally collected in the state of Paraná (Brazil) parasitizing H. zea eggs. Alternatively, if the initial population of T. atopovirilia had higher genetic variability, although kept in laboratory for a few generations, the possibility of finding a more aggressive haplotype toward D. saccharalis is greater.…”

“…Trichogramma atopovirilia has been reported parasitizing eggs of D. saccharalis in rice fields in the states of Tocantins and Piauí, northern and northeastern Brazil (Silva, 2018, unpublished data), and in the Tucumán province in Argentina (Isas et al, 2016). According to Browning and Melton (1987), parasitism of T. atopovirilia in D. saccharalis eggs is low compared to T. fuentesi Torre.…”

Studies on aggressiveness of parasitoids, as assessed by their parasitism against pests, used in biological-control programs are highly important to select the most suitable species and/or strain to control insect pests. The present study investigated whether the egg parasitoid Trichogramma galloi Zucchi, an efficient control agent for sugarcane borer Diatraea saccharalis (Fabricius) in Brazil, could be replaced by Trichogramma atopovirilia Oatman & Platner, a parasitoid easier to mass-produce, since it has been found parasitizing D. saccharalis eggs in the warmest region of Brazil and Argentina. Three strains of the genus Trichogramma were compared: T. atopovirilia (ATP strain) reared on a factitious host Anagasta kuehniella (Zeller); T. atopovirilia isoline ATP-I, reared on D. saccharalis eggs for six generations; and T. galloi, reared on A. kuehniella eggs. We measured parasitism of each strain for 72 h and for the entire life span, parasitism rate per cluster of D. saccharalis eggs, number of parasitoids emerged (parasitism viability), and parasitoid life span. The results confirmed that T. galloi is the best species for D. saccharalis control, showing higher control potential, since parasitism and emergence rate were higher for this species. Although T. atopovirilia ATP-I performed reliably in all parameters, T. galloi exceeded and was the most indicated for mass-rearing in control programs for sugarcane borer.

Essential oils cause detrimental effects on biological parameters of Trichogramma galloi immatures

Essential oils from botanical extracts used for insect pest control should be both effective and have low impact on natural enemies. The objective was to evaluate the effects of ten essential oils on the biological and reproductive parameters in two Trichogramma galloi Zucchi (Hymenoptera: Trichogrammatidae) generations. The emergence F 1 generation of T. galloi was reduced by more than 30% with Allium sativum, Carapa guianensis, Citrus sinensis, Neem and Syzygium aromaticum. Zingiber officinale reduced the T. galloi emergence of the F 1 and F 2 generations by between 30 and 99%. The longevity of the F 1 generation was reduced by more than 50% with Z. officinale at the pre-pupae and pupae stages. All oils reduced the parasitism rate of the F 1 generation in the egg-larva and pre-pupa stages. Allium sativum, C. guianensis and C. sinensis, Neem and Origanum vulgare reduced parasitism by between 30 and 79%. Zingiber officinale was slightly and moderately harmful to the F 1 and F 2 generations, respectively, for the T. galloi parasitism. The sex ratio of the two T. galloi generations was not affected by the essential oils. The low side effects of the oils on the F 2 generation, except for Z. officinale (the most harmful oil), suggest that T. galloi developed some post-transgenerational tolerance/resistance mechanisms to these oils and/or their components. The A. sativum, C. guianensis, C. sinensis, Neem, O. vulgare, S. aromaticum and Z. officinale oils were not selective for T. galloi. Mentha piperita, Piper nigrum and Thymus vulgaris essential oils can be included in integrated pest management programs for this parasitoid.
