“…Amongst the main natural enemies of C. anonella are species of Cotesia (Hymenoptera: Braconidae, Microgastrinae), but this parasitoid is not effective. In a field survey of the biological forms of C. anonella and its natural enemies carried out by Broglio‐Micheletti (1999), the presence of a total of 2019 specimens of the pest were reported together with 991 parasitic species (pupae, parasitic larvae and adults) of Cotesia , Rhysipolis and Xiphosomella . However, the incidence of parasitism of the pest by these three species was low (ca 33%), although Cotesia species were regularly encountered, being present in nearly all of the affected fruit harvested.…”

“…Currently, therefore, in order to control the damage caused by C. anonella , farmers are forced to rely heavily on the use of insecticides and on specific culture practices such as the destruction of infested fruits and the protection of young fruits by covering them individually with perforated plastic bags (Arango 1975; Melo et al. 1983; Broglio‐Micheletti 1999).…”

The Annona fruit borer, Cerconota anonella, causes significant damage to the fruits of Annona squamosa (custard apple) and A. muricata (soursop). The methods currently available for the control of this pest are costly and new techniques, possibly involving the use of pheromones for trapping or disrupting the mating cycle of the insect are required. In order to provide the basic information required for the development of new control systems, the reproductive behaviour of the moth was observed under laboratory conditions. The calling and courtship behaviours exhibited by virgin females and males of C. anonella commenced at the eighth hour of the scotophase and continued for a 3.5-h period. Males were attracted by conspecific females as young as 1 d old, and showed a courtship behaviour composed of three steps: antennation, wing fanning and short flights. Mating mainly occurred when both males and females were between 2 and 5 d old, but maximum activity was observed on the third day after emergence. Receptive females elevated their wings, showing their abdomens where the abdominal hairpencils were already exposed. As part of the courtship repertoire and immediately prior to copula, males performed pronounced sideways movements of their abdomens, a behaviour that appears to be exclusive to C. anonella.

“…Apanteles sp. is the main natural enemy of C. anonella larvae (Broglio‐Micheletti and Berti‐Filho ). Due to parasitic activity, the mortality of C. anonella is highest after eclosion and before entering the fruits and lower when the larva is inside the fruit (Fennah ).…”

The Annona fruit borer, Cerconota anonella Sepp., is a serious agricultural pest in many tropical areas of the world. The identification of an attractant for male C. anonella could offer new methods for pest detection and control. A mixture of compounds extracted from female C. anonella elicited antennal depolarization in the male borer. These compounds were identified as octadecanal, 1-octadecanol, octadecyl acetate, (Z)-octadec-9-enal (Z9-18:Ald), (Z)-octadec-9-en-1-ol (Z9-18:OH) and [(Z)-octadec-9-enyl] acetate (Z9-18:Ac) by one-and two-dimensional gas chromatographymass spectrometry. In laboratory bioassays, synthetic individual compounds as well as synthetic mixtures were found to be attractive to males. In addition, field tests using Delta traps with 1 mg of the ternary mixture composed of Z9-18:Ac, Z9-18:Ald and Z9-18:OH in the ratio of 1 : 3 : 5 caught as many males as traps containing virgin females. The ternary mixture of Z9-18:Ac, Z9-18:Ald and Z9-18:OH was identified as attractant to C. anonella males and can be used to detect and control populations of this insect in Annonaceae plantations.

“…Silva (1991) utilizou um delineamento inteiramente casualizado para testar se há diferença entre os tempos de vida de um crisopídeo submetidos a diferentes temperaturas. Micheletti (1999), utilizando dados de longevidade retirados de levantamentos realizados em campo, estimou a sobrevivência de fêmeas e machos de Cerconota anonella ajustando a distribuição Weibull aos dados. Esses estudos anteriormente mencionados foram realizados utilizando-se a informação completa.…”

RESUMO Apesar da grande quantidade de pesquisas e trabalhos publicados sobre o tempo de vida na área da entomologia, não é comum encontrar algum que tenha utilizado as técnicas de Análise de Sobrevivência. Com este trabalho, objetivou-se avaliar a possibilidade de aplicar mecanismos de censura em dados entomológicos e estudar a viabilidade da aplicação do teste log-rank. Foram utilizados dados reais entomológicos sem censura de machos e fêmeas da Ceraeochrysa cubana e, a partir deles, montou-se uma sub-rotina em SAS ® , na qual, por meio de simulação, introduziram-se as censuras aleatória e do tipo I, aplicando, assim, o teste log-rank para comparação das curvas resultantes e para diferentes porcentagens de censura. Utilizando os dados reais e os gerados por simulação, foi detectado que, com um aumento da presença de censura, a precisão do teste log-rank foi diminuindo. TERMOS PARA INDEXAÇÃO:Análise de sobrevivência, censura, tempo de vida. VIABILITY OF THE APPLICATION OF TYPE I CENSORING MECHANISMS AND RANDOM IN ENTOMOLOGICAL DATAABSTRACT In spite of the great amount of research and works published about the lifetime in the area of entomology, it is not common to find some which had utilized techniques of Survival Analysis. This work has the objectives to evaluate the possibility of applying censoring mechanisms in the entomological data and to study the viability of the application of log-rank test. Real entomological data without censoring of males and females of Ceraeochrysa cubana were utilized. By means of simulation a sub-routine was set up in SAS ® in which, the random and type I censoring were introduced. Applying the log-rank test for comparing the resulting curves, this for different percentage of censure. Utilizing the real and simulation the data, it was detected with an increase of censoring presence, the accuracy of the log-rank test has been decreasing. INDEX TERMS:Censoring, lifetime, survival analysis. INTRODUÇÃOEm um experimento que analisa o tempo de vida de insetos, o descarte da informação de interesse pela perda de indivíduos é uma forma incorreta de analisar os dados. Isso ocorre porque a presença das observações incompletas no estudo justifica-se pelo fato de elas fornecerem, ainda, informações sobre o tempo de vida. Sem a presença desses dados, não seria possível realizar uma boa estimação de parâmetros e, assim, fazer uma análise adequada.Para realizar uma análise correta e confiável de um experimento como o citado acima, é fundamental a utilização das técnicas de Análise de Sobrevivência. Essa é a área da estatística que tem como principal interesse analisar dados de tempos de vida que envolvem algumas observações cujas informações são incompletas (dados censurados). Entre as diversas áreas de aplicação desses métodos, pode-se citar a medicina, a engenharia e as ciências sociais.Áreas menos exploradas estão relacionadas com estudos entomológicos nos quais avaliam-se, entre outras, variáveis relacionadas com o tempo de sobrevivên-cia de insetos-pragas quando o ambiente natural desses é...
