Performance of Anastrepha obliqua (Diptera, Tephritidae) larvae fed on artificial diets
Provedor de dados: 76
Autores: Fontellas-Brandalha,Tânia M. L.; Cresoni-Pereira,Carla; Leal,Thamara A. B. S.; Medeiros,Luanda; Zucoloto,Fernando S.
Moscas das frutas do gênero Anastrepha Schiner, 1868 são conhecidas por sua importância econômica devido aos danos que elas causam nos frutos comerciais. As exigências nutricionais dos estágios imaturo e adulto são diferentes e as larvas não se desenvolvem bem utilizando a mesma dieta do adulto. Embora as necessidades nutricionais básicas dos insetos sejam bem conhecidas, existe ainda o problema de elaborar dietas de criação adequadas para espécies com necessidades específicas. O objetivo deste trabalho foi verificar o efeito de diferentes tipos e quantidades de carboidratos na dieta sobre a performance larval de Anastrepha obliqua (Macquart, 1835). Larvas foram criadas individualmente em tubos de ensaio contendo uma das dietas artificiais a serem testadas...

Associative learning in wild Anastrepha obliqua females (Diptera, Tephritidae) related to a protein source
Provedor de dados: 76
Autores: Cresoni-Pereira,Carla; Zucoloto,Fernando S.
The aim of the present study was to determine whether wild adult Anastrepha obliqua (Macquart, 1835) females are able to associate a compound (quinine sulphate - QS) not related to their habitual diet with a protein-enriched food. Females were first fed on diets based on brewer yeast and sucrose containing or not QS. The groups were then allowed to choose between their original diets and a diet with or without QS, depending on the previous treatment, and between a diet based on agar and a diet containing agar and QS. When the nutritional value of the diets was adequate, the females did not show any preference for the diet with or without QS. With respect to the agar diet and the agar + QS diet, females previously fed on a nutritive diet containing QS...

Oviposition preference hierarchy in Ceratitis capitata (Diptera, Tephritidae): influence of female age and experience
Provedor de dados: 76
Autores: Joachim-Bravo,Iara S.; Fernandes,Odair A.; Bortoli,Sérgio A.; Zucoloto,Fernando S.
The influence of two factors, age and previous experience, on the oviposition hierarchy preference of Ceratitis capitata (Wiedemann, 1824) females was studied. Two populations were analyzed: one reared in laboratory during 17 years and the other captured in nature. In the first experiment the oviposition preference for four fruits, papaya, orange, banana and apple was tested at the beginning of oviposition period and 20 days past. The results showed that the wild females as much the laboratory ones had an oviposition preference hierarchy at the beginning of peak period of oviposition. However this hierarchic preference disappeared in a later phase of life. In the second experiment the females were previously exposed to fruits of different hierarchic...

Influence of protein on feeding behavior of Ceratitis capitata Wiedemann (Diptera: Tephritidae): comparison between immature males and females
Provedor de dados: 82
Autores: Plácido-Silva,Maria do C.; Zucoloto,Fernando S.; Joachim-Bravo,Iara S.
The objective of this work was to compare the influence of dietary protein on performance and feeding behavior of immature males and females of Ceratitis capitata (Wiedemann). The protein source was beer yeast at 6.5 and 1.5 g.100 ml-1. The following parameters were evaluated: percentage of emergence, total life cycle, adult size, diet consumption, feeding preference and discrimination threshold for yeast. Immature adults showed similar protein requirements regardless of sex. Both males and females showed similar feeding behavior, preferring to feed on the diet with higher protein content. The discrimination threshold for levedure in both sexes was 0.4 g.100 ml-1. We concluded that immature males of C. capitata show similar protein requirements as the...

Importance of larval migration (dispersal) for the survival of Ascia monuste (Godart) (Lepidoptera: Pieridae)
Provedor de dados: 82
Autores: Barros-Bellanda,Helen C.H.; Zucoloto,Fernando S.
Insect species whose larvae have high mobility, such as Ascia monuste (Godart), show a poor discriminatory oviposition behavior with respect to the quantity of food. Such behavior in A. monuste is influenced positively by the spatial and temporal abundance of kale (Brassica oleracea Var. acephala), its main host, in nature. A. monuste caterpillars frequently migrate in search of food to complete their development and even smaller larval clusters at about 20 individuals are not supported by the resources provided by a medium-size kale plant. Migration (dispersal) of 5th-instar larvae was necessary both in groups feeding on plants confined in cages and on plants growing in nature, and migration was successful when the plants were close to one another. The...

The presence of the sexual partner and nutritional condition alter the Anastrepha obliqua MacQuart (Diptera: Tephritidae) protein discrimination threshold
Provedor de dados: 82
Autores: Cresoni-Pereira,Carla; Zucoloto,Fernando S.
The minimum protein amount that Anastrepha obliqua MacQuart can detect in its alimentary source is variable, though the causes of such variation are not very well known. In this study, the authors tested whether the sexual partners nutritional condition and presence devoid of direct contact alter the A. obliqua protein discrimination threshold. Male and female insects were assigned to groups as follows: (i) newly emerged, (ii) deprived of protein source (yeast) during 18 days, (iii) non-yeast-deprived during 18 days, (iv) yeast-deprived in the presence of equally yeast-deprived sexual partners, (v) yeast-deprived in the presence of non-yeast-deprived partners, (vi) non-yeast-deprived with yeast-deprived partners and (vii) non-yeast-deprived with...

Effects of different protein concentrations on longevity and feeding behavior of two adult populations of Ceratitis capitata Wiedemann (Diptera: Tephritidae)
Provedor de dados: 82
Autores: Plácido-Silva,Maria do Carmo; Silva Neto,Alberto M. da; Zucoloto,Fernando S.; Joachim-Bravo,Iara S.
The effects of protein intake on two adult male and female populations of Ceratitis capitata Wiedemann were assessed. One population consisted of flies reared for twenty years in the laboratory (Lab-pop); the other population consisted both of flies reared in the laboratory for approximately fifteen years and of the periodically introduced wild flies (Hybrid-pop). Three diets were tested: a no-yeast diet and two diets containing yeast (protein source) at the concentrations 6.5 g or 1.5 g per 100 ml diet. The parameters analyzed were: adult longevity, diet intake with and without yeast, and discrimination threshold for yeast. Protein intake increased Lab-pop adult longevity and did not affect longevity of the Hybrid-pop. Longevity in each population was...

Effect of sucrose ingestion on the performance of wild Anastrepha obliqua (Macquart) females (Diptera: Tephritidae)
Provedor de dados: 82
Autores: Fontellas,Tânia M.L.; Zucoloto,Fernando S.
Carbohydrates are the main source of energy for insects and the lack of these nutrients in the diet can cause serious damage to the biology of these arthropods. In order to better understand the effect of sucrose on the performance and dietary selection of adult Anastrepha obliqua (Macquart), the following experiments were carried out: 1) effect of different amount of sucrose on diet ingestion, longevity and egg production; 2) dietary selection that contains different amounts of sucrose, and 3) discrimination threshold for sucrose in adult individuals deprived or not of carbohydrates. The control diet showed the best results in relation to ingestion, longevity and egg production for these species, probably due to the fact that it presents an optimal...

Selection of oviposition sites by wild Anastrepha obliqua (Macquart) (Diptera: Tephritidae) based on the nutritional composition
Provedor de dados: 82
Autores: Fontellas-Brandalha,Tânia M.L.; Zucoloto,Fernando S.
Few works have studied in detail the types of nutrients associated to hosts which are attractive to females of Anastrepha obliqua (Macquart) and influence the choice of the oviposition site. The relationship of the males in the physiology and in the behavior of those females has also been scarcely studied and some ecological relationships seem to be quite important for the knowledge of this species' biology. Our objective in this study was to evaluate the discriminatory behavior of A. obliqua between oviposition sites containing different nutrients. The presence of the male and the nutritional status of the female were also considered in this work. Two experiments were developed: in the first, the preference of A. obliqua females between artificial...

Effect of host age on the oviposition and performance of Ascia monuste Godart (Lepidoptera: Pieridae)
Provedor de dados: 82
Autores: Bittencourt-Rodrigues,Rebecca de S.; Zucoloto,Fernando S.
Ascia monuste Godart, known as the kale caterpillar, has a specialized diet on Brassicaceae and represents one of the main herbivores of this family in the Neotropical region. The objective of the present study was to determine the performance and oviposition preference of A. monuste for common kale Brassica oleracea (Brassicaceae, var. acephala) of different ages. The parameters used to assess performance were time to pupation and emergence, emergence rate, digestive indices, relative consumption and growth rates, number of eggs per female, hatching rate, and weight of the imagoes. Chemical and physical properties of young and old kale leaves were determined. In general, caterpillars feeding on new leaves showed better performance than those feeding on...

Selection of artificial hosts for oviposition by wild Anastrepha obliqua (Macquart) (Diptera, Tephritidae): influence of adult food and effect of experience
Provedor de dados: 92
Autores: Leal,Thamara A. B. S.; Zucoloto,Fernando S.
Several factors influence the selection of oviposition substrates by insects. The aim of the present work was to find answers to the following questions related to the oviposition behavior of Anastrepha obliqua. Can carbohydrates (glucose or sucrose) present in the adult diet have influence on the female preference for an oviposition substrate with similar composition? Can the previous experience with a host containing one of mentioned carbohydrates interfere in further selection of oviposition substrates? The results showed that the kind of carbohydrate present in the adult diet did not affect the female preference for an artificial oviposition substrate, neither when it was presented by itself nor in combination with brewer's yeast. The effect of...

Cannibalism studies on eggs and newly hatched caterpillars in a wild population of Ascia monuste (Godart) (Lepidoptera, Pieridae)
Provedor de dados: 92
Autores: Zago-Braga,Rosana C.; Zucoloto,Fernando S.
Ascia monuste (Godart), also known as cabbage caterpillar, is considered herbivorous and specialist in Brassicaceae; however, it performs cannibalism. Experiments carried out in this work aimed to quantify the cannibalism occurrence in A. monuste, to verify whether cannibalism interferes in the species performance and to check whether cannibalism is influenced by the population size. The parameters used in order to evaluate the performance were time of development, adults weight and size, fecundity, oviposition and survival rate. Cannibalism occurred in all larval instars. There was a tendency to increase the cannibalism practice as the number of co-specific increased (potential preys). Cannibalism was more intense in larvae at the end of larval...

Effects of sex, host-plant deprivation and presence of conspecific immatures on the cannibalistic behavior of wild Ascia monuste orseis (Godart) (Lepidoptera, Pieridae)
Provedor de dados: 92
Autores: Santana,Alessandra F. K.; Zago,Rosana C.; Zucoloto,Fernando S.
Effects of sex, host-plant deprivation and presence of conspecific immatures on the cannibalistic behavior of wild Ascia monuste orseis (Godart) (Lepidoptera, Pieridae). The specialist cabbage caterpillar Ascia monuste orseis (Lepidoptera, Pieridae) feeds on plants of the Brassicaceae family, but may eventually ingest conspecific eggs and larvae during the larval stage. The present study examines feeding behavior of 4th and 5th instar cabbage caterpillars in relation to sex, host-plant deprivation and presence of conspecifics. We recorded number of egg ingested per larvae, developmental indices and duration of feeding, exploratory and resting behavior. Kale deprived caterpillars presented high rates of cannibalism, development delay and decreased...

Nutritive value of beer yeast for Eratiris capitata (Diptera, Tephritidae)
Provedor de dados: 104
Autores: Cocareli,Neuza Maria; Ferro,Maria Inês T.; Zucoloto,Fernando S.
Investigations of food requirements were carried out to determine the minimum amount of beer yeast needed to produce the best development of Ceratitis capitata. Variations in pupation time, emergence time, pupation percentage, emergence percentage, and ovarian development were directly related to increased amounts of beer yeast in the diet. Results indicate that the appropriate range of beer yeast is about 4.0 to 4.5 g/150 ml of diet.
