Species Being

Phytoseiidae (Acari: Mesostigmata) is an important family of predatory mites, with some species being commercialized as biological control agents for the control of phytophagous mites and small insects. In Peru, 65 species of this family have been recorded so far, with Amblyseius being the most diverse genus, with 11 species. The aim of this study is to report for the first time the presence of Amblyseius tamatavensis Blommers, 1974 in Peru. In South America, this species has so far been reported only in Brazil and Venezuela. In Peru, A. tamatavensis was found on orange plants [Citrus sinensis (L.) Osbeck] in the district of Pangoa, department of Júnin. In the laboratory, collected specimens were observed to feed on Phyllocoptruta oleivora (Ashmed, 1879) (Acari: Eriophyidae) and Frankliniella occidentalis (Pergande, 1895) (Thysanoptera: Thripidae). Studies to verify the potential of this species as a biological control agent for pests occurring in Peru should be conducted. A key to the Amblyseius species recorded in Peru is presented.

Abstract Neosieulus (Cydnodromus) collegae (De Leon) (Acari:Phytoseiidae) is a heretofore relatively unknown species of predatory mite. In an olfactometer, female predators were attracted to kairomones produced by Tetranychus urticae Koch, Oligonychus ilicis (McGregor), O. ununguis (Jacobi), Eotetranychus hicoriae (McGregor), and E. sexmaculatus (Riley). Predators were repelled by odors emanating from lima bean leaves treated with Mavrik (fluvalinate) and Ammo (cypermethrin), but unresponsive to those treated with Tame (fenpropathrin) and Talstar (bifenthrin). This predator species was tolerant of residues of Vendex (hexakis), Omite (propargite), Pentac (dienochlor) and Avid (abamectin) but not to residues of Tame (fenpropathrin) and Kelthane (dicofol). Eggs of T. urticae treated with Tame (fenpropathrin) were toxic to the predator when consumed. Female N. collegae would not consume eggs treated with Avid (abamectin); starvation reduced fecundity. Prey eggs treated with Vendex (hexakis) and Omite CR (propargite) were consumed without affecting predator fecundity or mortality. Eggs treated with Pentac (dienochlor) or Kethane (dicofol) were consumed, but significantly reduced predator fecundity. Predators released into plots in a commercial nursery during winter in north Florida reduced field populations of T. urticae within 20–30 days, if released in high numbers. Neosieulus collegae may have significant potential as a biological control agent in nursery crops for control of mite pests.

Direct Toxicity

Slide dip bioassays were conducted to determine the direct toxicity of insecticides, acaricides, fungicides, and herbicides commonly used in vineyards in Virginia to Neoseiulus fallacis (Garman) (Acari: Phytoseiidae), a predatory mite under consideration as a biological control agent for spider mites (Acari: Tetranychidae). Among the insecticides and acaricides tested in the laboratory, carbaryl, azinphos-methyl, phosmet, cyhexatin, and pyridaben caused significantly (P ≤ 0.05) higher mortality than the control treatment. None of the fungicides tested were toxic to the predator, but three herbicides caused high mortality. Glufosinate caused 100% mortality after 24 h, and both oxyfluorfen and paraquat had adverse effects on N. fallacis. The use of materials that were found to be toxic to the predator may not be compatible with releases of N. fallacis into Virginia vineyards. However, incorporating materials that appear to have no direct toxicity to the predator into an integrated pet management program could improve the survival rate of released N. fallacis while still protecting this high value crop from other pests.

Two Spotted Spider Mite

The two-spotted spider mite Tetranychus urticae is a dangerous polyphagous pest of agricultural and ornamental plants. In a commercial greenhouse treated with acaricides or biological control using predatory mite Phytoseiulus persimilis individual varieties of roses differed significantly in terms of the average annual infestation by the pest mite. On the poorly populated rose varieties, the biological control agent application was more effective as compared to the acaricides. To effectively control the pest, the required predatory mite rates were 4.6–8.7 times higher on varieties with a minimal spider mite infestation (Aqua and Deep Water) as compared to the maximal pest infestation (Heaven and Brazil).
