ABSTRACT The population of the caterpillar Diatraea saccharalis (Lepidoptera: Crambidae) has increased in the crop of sugarcane in recent years. Although the control of this insect is traditionally carried out through biological control, the use of phytosanitary products has still been necessary. Therefore, the goal of this work was to evaluate the performance of different insecticides in sugarcane borer control, as well as the effect on productivity and total recoverable sugar (TRS). The experiment was conducted in a randomized experimental delineation of blocks, with six treatments and four blocks. Treatments consisted of five insecticides and one control group (without application of insecticide). For calculating the D. saccharalis infestation index, monthly samplings were performed every 30 days, for 12 months. After this period, the final D. saccharalis infestation index was evaluated and calculated for each treatment. In order to compare productivity among procedures, four central lines were collected from each plot. Thus, the samples were weighed for the productivity calculation (TCH) and sent to the laboratory for the total recoverable sugar (TRS) analysis. The chloranthraniliprole (350) insecticide provided a lower index of sugarcane borer infestation, in addition to greater productivity when compared to the other insecticides. There was no significant difference in the parameter of total recoverable sugar (TRS) among treatments.

A capacidade do parasitoide de localizar e parasitar o hospedeiro estão diretamente relacionados ao sucesso do controle biológico de pragas. Diante disso, o presente trabalho avaliou o efeito da idade de Cotesia flavipes Cameron na capacidade busca e no parasitismo em lagartas de Diatraea saccharalis (Fabricius) em condições de laboratório. Realizou-se uma liberação de 2000 parasitoides com 24 horas de idade. Foram colocados 40 internódios infestados artificialmente com a broca, na distância de cinco e dez metros, num total de 80 colmos por avaliação, durante seis dias. Constatou-se que no primeiro dia de liberação houve a maior porcentagem de parasitismo, diferindo apenas do quinto e sexto dia. Conclui-se que C. flavipes pode parasitar até 120 horas de vida em condições de laboratório e recomenda-se a liberação de indivíduos com 24 horas de vida por apresentarem maior percentual de parasitismo nessa idade. Ability to Quest and Parasitism of Cotesia flavipes Cameron (Hymenoptera: Braconidae) on Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) Larvae Abstract. The ability of the parasitoid to locate and parasitize the host is directly related to the success of biological control of pests. The effect of Cotesia flavipes Cameron’s age on the ability to quest and parasitism larvae of Diatraea saccharalis (Fabricius) in laboratory conditions was evaluated. An amount of 2,000 adults (24 hours aged) was released. Fourteen sugarcane borer artificially infested internodes were 5 and 10 m placed apart each other, comprising eighteen stalks in each evaluation, during six days. The higher parasitism rate was observed in the first day after parasitoid release, with significant differences from the fifth day on. Therefore, C. flavipes is able to efficiently parasitize until its first 120 hours of life in laboratory conditions. It makes possible a recommendation of 24-hours aged parasitoid releases, that possibly will be more efficient in the sugarcane borer biological control.

Resumo. Durante o manejo da cultura da cana-de-açúcar são utilizados diversos produtos fitossanitários que podem afetar o desempenho de parasitoides, inimigos naturais da broca-da-cana, Diatraea saccharalis (Fabricius) e consequentemente, o controle biológico da mesma. Assim, objetivou-se avaliar em laboratório o efeito de herbicidas e reguladores de crescimento de plantas utilizados na cultura da cana-de-açúcar, sobre a sobrevivência, e parasitismo de adultos do parasitoide de ovos Trichogramma galloi Zucchi, assim como sobre a emergência do parasitoide (F1). Os produtos testados foram: Clomazone, Diuron + Hexazinone (herbicidas); Sulfometuron-methyl e Trinexapac-ethyl (reguladores de crescimento de plantas) nas maiores doses recomendadas à cultura. Ovos de D. saccharalis foram imersos durante 5 segundos em uma das caldas químicas e, após secos por 1 hora, oferecidos às fêmeas de T. galloi, totalizando 20 repetições. Avaliou-se a mortalidade e o número de ovos parasitados pela geração F0, assim como, a emergência da geração F1 de T. galloi, sendo os produtos classificados quanto à toxicidade, conforme percentual de redução da sobrevivência, parasitismo e emergência do parasitoide. Em relação à sobrevivência de T. galloi, número de ovos parasitados pela F0 e a emergência da F1, Clomazone e Trinexapac-ethyl foram classificados como levemente prejudicais. Diuron + Hexazinone e Sulfometuron-methyl foram inócuos em todos os parâmetros avaliados, com exceção do parasitismo, onde Diuron + Hexazinone foi classificado como levemente prejudicial. Conclui-se que, Clomazone, Diuron + Hexazinone, Trinexapac-ethyl e Sulfometuron-methyl são inócuos ou levemente prejudiciais a sobrevivência e parasitismo (F0) de adultos de T. galloi, e a emergência (F1) desse parasitoide, em laboratório.Herbicides and Plant Growth Regulators Used in SUGARCANE and their Action on Adult Trichogramma galloi Zucchi (Hymenoptera: Trichogrammatidae) Abstract. During crop sugarcane management, several used pesticides can affect the performance of parasitoids, natural enemies of sugarcane borer, Diatraea saccharallis (Fabricius) and consequently the biological control ofit. Thus, the objective was to evaluate in laboratory the effect of herbicides and plant growth regulators used in the sugarcane crops on survival and parasitism in adults of the eggs parasitoids, Trichogramma galloi Zucchi. The products tested were the herbicides Clomazone and Diuron + Hexazinone, and the plant regulators Sulfometuron-methyl and Trinexapac-ethyl, all in the higher recommended dosages for sugarcane. The eggs of D. saccharalis were immersed during 5 seconds in chemical solutions and, after dry for 1 hour, offered to T. galloi females with 20 repetitions. We evaluated the mortality and number of eggs parasitized by the F0 generation of T. galloi, as well as the emergence of the F1. The products were classified by their toxicity, according to the percentage of reduction in the survival, parasitism and emergence of the parasitoid. In relation to the survival of adult T. galloi, the number of eggs parasitized by F0 as well as the percentage of F1 emergence, clomazone and trinexapac-ethyl were classified as slightly harmful. Diuron+hexazinone and sulfometuron-methyl were harmless in all parameters, except for parasitism, where diuron+hexazinone was classified as slightly harmful. We conclude that clomazone, diuron+hexazinone, trinexapac-ethyl and sulfometuron-methyl, are harmless or slightly harmful the survival and parasitism (F0) of T. galloi adults and emergence (F1) of this parasitoid in the laboratory.

Abstract The sugarcane borer Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) is considered the main sugarcane pest in many countries. The use of plant genotypes less preferred by insects are among the alternative methods to control this species which can be used alone or associated with other control methods such as biological control in Integrated Pest Management (IPM) programs. We assessed if the nonpreference for oviposition of D. saccharalis in sugarcane genotypes established by seedlings is different according to ripening group and plant age. For that purpose, four experiments were performed: 1) seedlings of early-ripening genotypes, 2) seedlings of late-ripening genotypes, 3) and mix of early- and late-ripening genotypes, seedlings, and 4) plants. There were least preferred genotypes for oviposition by D. saccharalis among seedlings of early-ripening (RB965902 and RB966928) and late-ripening (RB987935) genotypes. It was also observed when the groups were mixed as seedlings (RB965902) or plants (RB925345). The nonpreference for egg deposition in different ripening groups and plant age might be useful to integrate with other strategies for the management of D. saccharalis. Moreover, results of egg distribution might indicate the likely position of resistance factors on leaves, whether morphological or chemical.
