“…The experiment was conducted in the "Laboratório de Entomologia Aplicada -LEA" of the "Universidade Federal do Ceará (UFC)", Fortaleza, Ceará State, Brazil. The "guaraciaba" line of T. pretiosum used was collected when naturally parasitizing eggs of Neoleucinodes elegantalis (Guenée) (Lepidoptera: Crambidae) on tomato (Solanum lycopersicum L.) fruit (Oliveira et al, 2020). The population of S. frugiperda with frequency of resistant individuals was collected in commercial areas in the municipality of Quixeré, Ceará (Latitude 5°4′40′′S, Longitude 7°59′7″W, and mean Altitude of 25.0 m AMSL), with mean maximum temperature of 35.0°C and mean minimum of 22.0°C.…”

The possible interference of resistant pest’s populations to insecticides in natural enemies in the action thas not been clarified yet. Thus, this study aimed to evaluate Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) performance on Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) eggs with resistance frequency to the Metaflumizone over six generations of product exposure. Egg cards (2.0 x 7.0 cm) containing eggs from two populations of S. frugiperda, (resistant to Metaflumizone and the other susceptible), were exposed to T. pretiosum females for 24 hours in free-choice and no-choice testing in three generations (G1, G4, and G6). A completely randomized experimental design was used with 25 replications, each consisting of an egg card (experimental unit) containing 20 eggs. The parameters evaluated were: parasitism (%), emergence (%), sex ratio, number of emerged parasitoids per egg and males/females longevity. ANOVA and Tukey test (P≤ 0.05) were applied on the results. Results showed a reduction in parasitism [41.0% (G1) and 28.4% (G4)], egg emergence (17.5%) and parasitoids/egg [16.2 (G4) and 17.2 (G6)] in eggs originating from the population with resistance frequency. Females emerging from G6 populations eggs without exposure to Metaflumizone had greater longevity (3.5 days more) than the resistant population. The sex ratio and male longevity were not affected. The results indicate a reduction in T. pretiosum activity if S. frugiperda populations have some frequency of resistance to Metaflumizone.

“…The experiment was performed in the 'Laboratorio de Entomologia Aplicada (LEA)' of the 'Universidade Federal do Ceará (UFC)', Fortaleza, Ceará State, Brazil. Two lines of T. pretiosum ("Ubajara" and "Guaraciaba") were used, which were collected naturally parasitizing N. elegantalis eggs in tomato fruit in commercial areas in the region of 'Serra da Ibiapaba', Ceará State, Brazil (Oliveira et al 2020). The first line was collected in the rural area in the municipality of Ubajara under a conventional tomato growing system, and the second line was collected in the municipality of Guaraciaba do Norte under an organic tomato growing system.…”

“…In accordance with the habit of the insect pest, a control alternative is the use of parasitoid wasps Trichogramma (Hymenoptera: Trichogrammatidae), because they parasitize the eggs of N. elegantalis, impeding the larval emergence and, consequently, the injuries they cause (Berti and Marcano 1991;Oliveira et al 2020).…”

This study aimed to evaluate the impact of temperature on the development of two lines of Trichogramma pretiosum (Hymenoptera: Trichogrammatidae), to determine the thermal requirements of this parasitoid wasp on Neoleucinodes elegantalis (Lepidoptera: Crambidae) eggs. The experiment was carried out with two lines (“Ubajara” and “Guaraciaba”, Ceará State) of T. pretiosum collected naturally parasitizing eggs of N. elegantalis in tomato (Solanum lycopersicum) fruits. In this experiment, 40 eggs of the host N. elegantalis and 4 females of the parasitoids were used, with exposure to parasitism for 24 hours at 25 ± 1 °C, relative humidity of 70 ± 10 %, and 12-h photophase. At the end of this period, females were removed and the tubes were transferred to incubators (RH = 70 ± 10 %; 12-h photophase), exposed to 15, 20, 25, 30, or 35 °C, until emergence of the following generation of the parasitoids. The percentage of emergence, sex ratio, the number of parasitoids that emerged per egg, and cycle duration were assessed. The experiments were set up in a completely randomized experimental design with 5 treatments (temperatures) and 12 replicates. ANOVA was conducted and the means were compared by Tukey test (P < 0.05). The base temperatures were 10.77 °C and 10.86 °C and the number of generations per year were 33.29 and 35.63 for “Ubajara” and “Guaraciaba”, respectively. The study showed that temperature changed the biological parameters, and cycle duration of the “Ubajara” and “Guaraciaba” lines decreased as temperature increased.

“…Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) Parasitic wasps of the Trichogramma genus are widely used in crops against Lepidoptera caterpillars (Oliveira et al, 2020a). Wasps are released repeatedly into the crop during the cultivation period (Oliveira et al, 2020b).…”

“…The eggs of most species of moths, especially those of the Noctuidae family, can be parasitized, as they are generally ideally suited to the development of Trichogramma species. Problems only arise if moths of a specific species cover their eggs with hairs or wing scales or deposit the eggs in multiple layers (Oliveira et al, 2020a). The parasitic wasp searches through the plant from the bottom up and narrows its search area whenever a suitable egg is found (Malais and Ravensberg, 2003).…”

Biological control is a worldwide trend and has been prominent as an effective and compatible strategy for use in Integrated Pest Management programs. In Brazil, the control of these organisms using biological agents has been used in several agricultural systems, including floriculture. This paper approaches biological control from the perspective of the interaction between organisms in nature, applied as a pest management strategy. Knowledge about the dependence and reciprocity among populations in a natural environment is fundamental to understanding that this control method is nothing more than an exploiting of a natural ecological service. Considering that, for the biological control of a pest we must increase the population density of natural enemies, we report on the two main ways to achieve this increase: conservative biological control and augmentative biological control. The first is done by modifying the environment’s vegetation structure to favor natural enemies’ maintenance or their attraction to the crops. The second is done by mass rearing entomophagous and entomopathogen species with attributes that can ensure their function as control agents when released in crops. Among such agents, we emphasize those produced and marketed in Brazil for application in ornamental plants. Finally, we report on the technologies most recently employed to increase the appropriate use and the efficiency of these biological control agents.
