Ciclo de vida de Proprioseiopsis cannaensis (Muma) (Acari: Phytoseiidae) com diferentes tipos de alimentos

Abstract

-Several annual and perennial crops are severely attacked by mites from the family Eriophyidae, Tenuipalpidae and Tetranychidae. A suitable alternative commonly used in several countries for the control of these pest mites involve the use of predatory mites in the family Phytoseiidae. The phytoseiid fauna in the Brazilian natural vegetation is very rich, but nothing is known about the biology of most of these species, as it is the case with Proprioseiopsis cannaensis (Muma). The objective of this study was to determine biological parameters of P. cannaensis fed on pest mite species such as Phyllocoptruta oleivora (Ashmead) (Eriophyidae), Brevipalpus phoenicis (Geijskes) (Tenuipalpidae) and Tetranychus urticae Koch (Tetranychidae). To enable a comparison for different food sources, one of the treatments consisted of pollen from Typha angustifolia L. The study was conducted in the laboratory at 25 ± 1 o C, 80 ± 10% RH and Photophase of 12h. Proprioseiopsis cannaensis did not complete the development when it was fed on P. oleivora. Its fecundity was very low with all other food sources (maximum of 3.3 eggs/female with pollen of T. angustifolia). The values of r m for P. cannaensis were -0.05, -0.09 and 0.002 when fed on B. phoenicis, T. urticae and pollen respectively. The unsatisfactory results from the four types of food sources do not permit us to conclude that P. cannaensis utilizes mites from the family Eriophyidae, Tenuipalpidae, Tetranychidae or pollen from different plant species as principal sources of food in nature.KEY WORDS: Biology, life table, biological control, oviposition Um grande número de culturas anuais e perenes é severamente atacado por ácaros das famílias Eriophyidae, Tenuipalpidae e Tetranychidae. A maioria das espécies de ácaros-praga em todo mundo pertence a essas famílias, que têm ácaros exclusivamente fi tófagos (Jeppson et al 1975). No Brasil, a utilização de agrotóxicos é praticamente a única estratégia adotada para o controle dessas pragas. Dada a crescente preocupação mundial com os impactos ambientais que o acúmulo excessivo de agrotóxicos pode causar no ambiente e à saúde humana, o controle biológico tende a crescer cada vez mais no meio agrícola. Uma alternativa muito utilizada em alguns países para o controle daqueles ácaros-praga é a utilização de ácaros predadores.Phytoseiidae é a principal família de ácaros predadores. Ácaros dessa família têm sido empregados em diferentes cultivos, especialmente para o controle de ácaros Tetranychidae (Helle & Sabelis 1985, Gerson et al 2003, Zhang 2003. A fauna de fi toseídeos no Brasil parece bastante diversa, mais de 100 espécies desta família já foram relatadas no país (Moraes et al 2004) e, provavelmente, centenas de outras ainda serão relatadas. Proprioseiopsis cannaensis (Muma) é um dos fi toseídeos encontrados em diferentes partes do Brasil. A espécie é comumente encontrada na vegetação natural, tendo sido relatada nas regiões Norte, Nordeste e Sudeste do Brasil, e também em vários outros países americanos (Moraes et al 200...

“…. Bee pollen, which usually is a mixture of pollen from different plant species, has often been utilized in laboratory cultures . In Brazil, castor bean, cattail and bee pollen are widely available in nature, and bee pollen is commercially available worldwide.…”

Effect of pollen of different plant species on the oviposition of two phytoseiid mites (Acari: Phytoseiidae) commonly found in citrus orchards in the Brazilian Amazonia

“…The highest level of daily oviposition of A. aerialis in the present study was similar or slightly higher than that obtained by Castillo and Noronha (2008), when the predator was fed pollen of Typha angustifolia (1.3 eggs/female). This was expected, considering the numerous reports on the suitability of pollen of plants of this genus to phytoseiid species (McMurtry and Croft 1997;Furtado and Moraes 1998;Van Rijn and Tanigoshi 1999;Ferla and Moraes 2003;Lofego and Moraes 2005;Bellini et al 2010). For I. zuluagai the highest level of daily oviposition was also slightly higher than that obtained by Reis et al (1998) and Marques et al (2014) when fed with castor bean pollen (Ricinus communis L.) (0.7 and 0.6 egg/female respectively).…”

“…Diet: This species has been observed feeding on pollen and Tetranychidae, Tenuipalpidae and Eriophyidae mites. However, the data obtained didn't allow asserting that P. cannaensis utilizes these items as principal sources of food in nature (Bellini et al 2010).…”
