“…It was observed by the rarefaction technique and the wealth estimators Bootstrap (10.75), Jackknife 1 (10.07) and Chao 2 (9.44) a proximity between the wealth of observed and estimated families, only for the Jackknife 2 (13.95) estimator there was a distance, in which this one apparently indicated a greater number of families to be observed (Figure 3). The determination of sample adequacy is important for decision-making and correct use of sampling methods to estimate an insect population within the cultivated area (Resende et al, 2014). During the months of March, April, the end of August and the beginning of September, there was an increase in the population of individuals of the Curculionidae families, Scarabaeidae, Syrphidae and Noctuidae.…”

The objective of this work was to evaluate the fluctuation and population density of different families of insects by means of attractive food based on oleoresins and sugars in an area under soybean-oat succession. The experiment was carried out in the municipality of Cruz Alta, RS, according to Koppen type Cfa. During the months of March to September, 9 traps were installed with the alimentary attraction around an area of 10.5 hectares, the samplings in the traps were realized every two weeks, being the number of insects belonging to each family accounted for and used for data analysis. The families identified were Curculionidae, Scarabaeidae, Coccinellidae, Noctuidae, Apidae, Chrysomelidae, Syrphidae, Tenebrionidae, Chrysopidae and Pentatomidae. Among the most populous are: Curculionidae, Scarabaeidae and Noctuidae. The Bootstrap estimators (10.75), Jackknife 1 (10.07) and Chao 2 (9.44) indicated proximity between the number of families observed (10) and estimated only for the Jackknife 2 estimator (13.95), there were more families. The soybean-oat succession provides a population increase of herbivores to the detriment of natural enemies. Food-attractive traps based on oleoresins and sugars serve to monitor local entomofauna in areas of soybeans and oats in succession. RESUMO:O trabalho teve por objetivo avaliar a flutuação e densidade populacional de diferentes famílias de insetos por meio de atrativo alimentar à base de oleoresinas e açúcares em área cultivada na sucessão soja-aveia. O experimento foi realizado no município de Cruz Alta, RS, de acordo com Koppen do tipo Cfa. Durante os meses de março a setembro foram instaladas 9 armadilhas com o atrativo alimentar no entorno de uma área de 10,5 hectares, as amostragens nas armadilhas foram realizadas a cada duas semanas, sendo o número de insetos pertencentes a cada família contabilizados e utilizados para análise de dados. As famílias identificadas foram Curculionidae, Scarabaeidae, Coccinellidae, Noctuidae, Apidae, Chrysomelidae, Syrphidae, Tenebrionidae, Chrysopidae e Pentatomidae. Sendo das mais populosas: Curculionidae, Scarabaeidae e Noctuidae. Os estimadores de riqueza Bootstrap (10,75), Jackknife 1 (10,07) e Chao 2 (9,44) indicaram proximidade entre o número de famílias observadas (10) e estimadas; apenas para o estimador Jackknife 2 (13,95) verificou-se maior número de famílias. A sucessão soja-aveia propicia aumento populacional de herbívoros em detrimento dos inimigos naturais. Armadilhas com atrativo alimentar à base de oleoresinas e açúcares servem para o monitoramento da entomofauna local em áreas de soja e aveia em sucessão.

“…In Brazil, Chrysoperla and Ceraeochrysa genus stands out. Ceraeochrysa cubana species (Hagen, 1861) (Neuroptera: Chrysopidae), known commonly as trash-carrying chrysopids, is found in different crops, as maize and tomato (RESENDE et al, 2014;MOURA et al 2015), and is an important predator of many pests in its larval stage (ALCANTRA et al, 2008;OLIVEIRA et al, 2014;NUNES et al, 2017). In addition, its ease rearing outside natural environment is a factor considered as essential.…”

Green lacewings can be mass reared to market their eggs. The ideal temperature is a main factor for egg storage or scheduling of insect production. This study aimed to evaluate the influence of Ceraeochrysa cubana adult feeding on incubation period and feasibility off eggs storage under different temperatures. Adults were submitted to four artificial diets: honey + brewer's yeast (standard diet), molasses + brewer's yeast, honey + bee pollen and molasses + bee pollen. Incubation period was recorded keeping eggs at six different temperatures: 21, 23, 25, 27, 29 and 31 °C. requirements. We determined the duration of the incubation period and egg feasibility of C. cubana. In addition, we estimated the base temperature (Tb) and thermal threshold (K) for the green lacewing incubation. Regardless of diet, incubation period decreases according to increased temperature, which is indicated between 21 and 29 °C for better development and egg feasibility. Adult feeding influences thermal constant, however, does not influence base temperature of the eggs, which varies from 15 to 18 °C. Our results can serve as a basis for the choice of adults' diet and temperature for the storage of eggs during the mass rearing of C. cubana.

“…The species Ceraeochrysa cubana (Hagen) (Neuroptera: Chrysopidae) has been found in different crops of economic importance, such as corn (Resende et al, 2014) and recommended for the control of insect pests (Alcantra et al Oliveira et al, 2014). Therefore, this work aimed to determine the development of C. cubana when fed with S. frugiperda, as well as the consumption, attack and handling of prey.…”

Mortality of neonate larvae and eggs of Spodoptera frugiperda has an important contribution to the management of this pest. This work aimed to determine the development, quantify the consumption, the time of search and handling of eggs of S. frugiperda by Cereaochrysa cubana. The duration of development and the survival of C. cubana were determined using eggs of the alternative prey Anagasta kuehniella; eggs, newborn caterpillars and combined feeding of egg + newborn caterpillars of S. frugiperda. The daily and total consumption, the search and handling time were also evaluated, comparing eggs and caterpillars of S. frugiperda as prey. The duration of the larvae to adult phase of C. cubana was prolonged when the food was newborn caterpillars or eggs + newborn caterpillars of S. frugiperda (35.7 and 34.6 days) when compared to eggs of A. kuehniella and S. frugiperda (25.5 and 25.9 days). The predator's larvae showed a shorter larval and adult period when fed with eggs in relation to caterpillars. Larval viability of C. cubana was lower when fed with eggs + newborn caterpillars. Higher consumption and shorter search and handling time on newborn caterpillars of S. frugiperda, compared to prey eggs, are carried out by larvae of C. cubana during the third instar.

Este trabalho objetivou determinar o desenvolvimento, quantificar o consumo, o tempo de busca e de manipulação de ovos de S. frugiperda por Cereaochrysa cubana. A duração do desenvolvimento e a sobrevivência de C. cubana foram determinadas empregando-se ovos da presa alternativa Anagasta kuehniella; ovos, lagartas neonatas e alimentação combinada de ovos + lagartas neonatas de S. frugiperda. Também foram avaliados os consumos diário e total, o tempo de busca e de manipulação, comparando-se ovos e lagartas de S. frugiperda como presa. A duração da fase de larva a adulto de C. cubana foi prolongada quando o alimento foi lagartas neonatas ou ovos + lagartas neonatas de S. frugiperda (35,7 e 34,6 dias) comparado a ovos de A. kuehniella e S. frugiperda (25,5 e 25,9 dias). Larvas do predador apresentam menor período de larva-adulto quando alimentados com ovos em relação a lagartas. A viabilidade larval de C. cubana foi menor quando alimentadas com ovos + lagartas neonatas. O maior consumo e menor tempo de busca e de manipulação sobre lagartas neonatas de S. frugiperda, em comparação aos ovos da presa, são realizados por larvas de C. cubana durante o terceiro instar.
