AbstractThe simultaneous infestation of a plant by several species of herbivores may affect the attractiveness of plants to the natural enemies of one of the herbivores. We studied the effect of coconut fruits infested by the pestsAceria guerreronisandSteneotarsonemus concavuscutum, which are generally found together under the coconut perianth. The predatory miteNeoseiulus barakiproduced lower numbers of offspring on fruits infested withS. concavuscutumand on fruits infested with both prey than on fruits withA. guerreronisonly. The predators were attracted by odours emanating from coconuts withA. guerreronis, but not by odours from coconuts withS. concavuscutum, even whenA. guerreroniswere present on the same fruit. FewerN. barakiwere recaptured on fruits with both prey or withS. concavuscutumthan on fruits with onlyA. guerreronis. Furthermore, the quality ofA. guerreronisfrom singly and multiply infested coconuts as food forN. barakidid not differ. Concluding, our results suggest thatN. barakidoes not perform well whenS. concavuscutumis present on the coconuts, and the control ofA. guerreronisbyN. barakimay be negatively affected by the presence ofS. concavuscutum.

AbstractCoconut is an important crop in tropical and subtropical regions. Among the mites that infest coconut palms, Aceria guerreronis Keifer is economically the most important. We conducted surveys throughout the coconut growing areas of Brazil. Samples were taken from attached coconuts, leaflets, fallen coconuts and inflorescences of coconut palms in 112 localities aiming to determine the occurrence and the distribution of phytophagous mites, particularly A. guerreronis, and associated natural enemies. Aceria guerreronis was the most abundant phytophagous mite followed by Steneotarsonemus concavuscutum Lofego & Gondim Jr. and Steneotarsonemus furcatus De Leon (Tarsonemidae). Infestation by A. guerreronis was recorded in 87% of the visited localities. About 81% of all predatory mites belonged to the family Phytoseiidae, mainly represented by Neoseiulus paspalivorus De Leon, Neoseiulus baraki Athias-Henriot and Amblyseius largoensis Muma; 12% were Ascidae, mainly Proctolaelaps bickleyi Bram, Proctolaelaps sp nov and Lasioseius subterraneus Chant. Neoseiulus paspalivorus and N. baraki were the most abundant predators on attached coconuts. Ascidae were predominant on fallen coconuts, while A. largoensis was predominant on leaflets; no mites were found on branches of inflorescences. Leaflets harboured higher mite diversity than the attached coconuts. Mite diversity was the highest in the state Pará and on palms surrounded by seasonal forests and Amazonian rain-forests. Neoseiulus paspalivorus, N. baraki and P. bickleyi were identified as the most promising predators of A. guerreronis. Analyses of the influence of climatic factors revealed that dry ambient conditions favour the establishment of A. guerreronis. Neoseiulus paspalivorus and N. baraki have differing climatic requirements; the former being more abundant in warm and dry areas, the latter prevailing in moderately tempered and humid areas. We discuss the significance of our findings for natural and biological control of A. guerreronis.

Citrus Red Mite

Citrus red mite (CRM) Panonychus citri is only a significant pest of citrus in New Zealand when the broadspectrum activity of insecticides targeting other key pests disrupts the activity of its natural enemies The longterm solution to CRM control is to eliminate the use of disruptive agrichemicals but until this happens effective miticides are needed to control CRM Two smallplot field trials were conducted in 2004 and 2005 in a lemon orchard in Kerikeri In the first trial two applications of milbemectin abamectin fenpyroximate or propargite were effective against eggs and motile life stages Oil at 1 was not as effective as milbemectin at suppressing the incidence of eggs on leaves 6 weeks after application but was more effective than a 05 rate In the second trial the Stethorus sp ladybird and Agistemus longisetus predatory mite reduced CRM populations in both unsprayed trees and trees treated with miticides

The coconut mite, Aceria guerreronis Keifer, is one of the main pests of the coconut tree (Cocos nucifera L.) worldwide. Its control is mainly based on the use of acaricides. However, due to the habitat of this pest mite, which is protected by fruit bracts that act as a physical barrier, chemical control is often inefficient. Thus, natural enemies have been studied as an alternative to acaricides. We evaluated the functional and numerical responses of Amblyseius aerialis (Muma) to increasing densities of A. guerreronis (40, 80, 160, 240 and 360) and additionally the oviposition rates of the phytoseiid A. aerialis over 11 days on different food sources: coconut pollen, A. guerreronis and a mix of pollen and A. guerreronis. Our results showed that Amblyseius aerialis showed a type III functional response, where prey consumption increasing as the density of A. guerreronis increased, with a maximum consumption of up to 175 prey per predator. All the prey densities allowed female oviposition. The number of eggs laid by A. aerialis increased with increasing prey density and stabilized between 240 and 360 A. guerreronis individuals, with an average oviposition of 1.7 eggs/female. Furthermore, our results showed that all the food sources (coconut pollen, A. guerreronis and a mix of pollen and A. guerreronis) supported oviposition. The mean oviposition was approximately 1.5 eggs/female on all the food sources. Our study suggests that A. aerialis can be effective in the biological control of A. guerreronis. However, further studies are needed to investigate whether A. aerialis can explore the habitat of A. guerreronis and if that prey can support the development of immature stages and the reproduction of A. aerialis.
