“…and other inflorescence feeding Lepidoptera, including detritus feeders. Some of these other Lepidoptera will damage female flowers, as Bondar ( 1940a , b ), Santana ( 2008 ), and Santana et al ( 2009 ) reported for Atheloca bondari and A. subrufella and Bondar ( 1940a , b ) reported for Cadra cautella . In this situation, the presence of B. nuciferae could lead to damage to female flowers, although the extent and frequency to which this happens would need to be investigated.…”

In 2006, Batrachedra nuciferae Hodges (Lepidoptera: Batrachedridae) was the first phytophagous insect to be reported from inflorescences of coconut, Cocos nucifera L. (Arecales: Arecaceae), in Trinidad, West Indies. At that time, it was suggested to be an introduced species contributing to decreasing coconut yields on the island and potentially a threat to other palms. In this preliminary study, inflorescences of coconut, seven indigenous palms, and six exotic ornamental palms were surveyed in several areas of Trinidad. Caterpillars of more than 10 species of Lepidoptera were found and reared through to the adult stage. Batrachedra nuciferae was positively identified. It was concluded that the caterpillars of B. nuciferae feed on pollen in the male flowers of coconut and palmiste or royal palm, Roystonea oleracea (Jacquin) O.F. Cook. There was no evidence that B. nuciferae bred on any of the other palms surveyed, but it is not conclusive that they do not do so. A parasitoid, Apanteles (sensu lato) sp. (Hymenoptera: Braconidae), of B. nuciferae was reared. On available information, B. nuciferae is more likely to be an indigenous species that has hitherto been overlooked than an introduced species. In view of what is known about damage-yield relationships and biological control agents, B. nuciferae is unlikely to cause yield losses to coconut, so control measures are not justified.

“…Os insetos foram mantidos a 25 ± 1,5 o C, 70 ± 5% de umidade relativa e fotofase de 13h. O método de criação de A. subrufella empregado neste estudo foi o de Santana (2008). Para a criação foram utilizados frutos do terceiro cacho de coqueiro anão-verde, após a abertura total da infl orescência, com aproximadamente 10 a 12 cm de comprimento e 8 a 10 cm de diâmetro, isentos de injúrias por pragas ou sintomas de fi topatógenos.…”

-Among the important pests of coconut, the coconut moth Atheloca subrufella (Hulst) is a signifi cant pest of fl owers and fruits, and is found across all coconut-producing regions in Brazil. We investigated the thermal requirements of A. subrufella and estimated the number of generations for two different growing coconut regions in Pernambuco State. The developmental time of all immature stages reduced as the temperature increased. The egg to adult period ranged from 19.3 to 59.8 days from 32ºC to 18 o C, respectively. The survival of the period from egg to adult was 25% at extreme temperatures (18 o C and 32 o C), while at the intermediate temperatures it was over 72%. Based on the thermal requirements determined for A. subrufella and the average temperatures determined for "Zona da Mata" and "Sertão" of Pernambuco State, it was estimated that A. subrufella is able to complete up to 13 generations per year in both areas. These results indicate that A. subrufella exhibited development and reproduction limited by temperatures higher than 32 o C and lower than 18 o C. However, based on the thermal requirements of A. subrufella and the mean temperatures of the "Zona da Mata" and "Sertão" of Pernambuco State, this pest can develop throughout the entire year.

“…Larvae of different species of moths feed on the male and female flowers of coconuts (Bondar, 1940; Moore, 2001; Cock and Burris, 2013). The moths can complete their life cycle in developing nuts (Bento et al ., 2006; Santana et al ., 2010), but their occurrence in nuts is very low. This suggests that the larvae of moths are not able to bore the exocarp of the nuts.…”

Because plant phenotypes can change in response to attacks by herbivores in highly variable ways, the distribution of herbivores depends on the occurrence of other herbivore species on the same plant. We carried out a field study to evaluate the co-occurrence of three coconut pests, the mites Aceria guerreronis (Acari: Eriophyidae), Steneotarsonemus concavuscutum (Acari: Tarsonemidae) and the moth Atheloca bondari (Lepidoptera: Pyralidae). The eriophyid mite Ac. guerreronis is the most important coconut pest around the world, whereas S. concavuscutum and At. bondari are economically important only in some areas along the Brazilian coast. A previous study suggested that the necrosis caused by Ac. guerreronis facilitates the infestation of At. bondari larvae. Because all three species infest the area under the perianths on coconuts and S. concavuscutum also causes necrosis that could facilitate At. bondari, we evaluated the co-occurrence of all three species. We found that the occurrence of At. bondari was positively associated with Ac. guerreronis, but negatively associated with S. concavuscutum. In addition, the two mite species showed negative co-occurrence. Atheloca bondari was found on nuts of all ages, but more on nuts that had fallen than on those on the trees, suggesting that nuts infested by At. bondari tend to fall more frequently. We discuss the status of At. bondari as a pest and discuss experiments to test the causes of these co-occurrence patterns.
