Life cycle, fecundity, and longevity of this mite were studied on fruits of four date palms, Phoenix dactylifera L. (Arecales: Arecaceae)(varieties: Deglet Noor, Alig, Kentichi, and Besser), under laboratory conditions at 27 ± 1 °C, 60 ± 10% RH. Total development time of immature female was shorter on Deglet Noor fruits than on the other cultivars. O. afrasiaticus on Deglet Noor had the highest total fecundity per female, while low fecundity values occurred on Besser. The comparison of intrinsic rates of natural increase (rm), net reproductive rates (Ro), and the survival rates of immature stage of O. afrasiaticus on the host plants suggests that O. afrasiaticus performs better on Deglet Noor fruits. The mite feeding on −1 Alig showed the lowest intrinsic rate of natural population increase (rm = 0.103 day ). The by guest on March 7, 2016 estimation of difference in susceptibility of cultivars to O. afrasiaticus is crucial for developing efficient pest control programs. Indeed, less susceptible cultivars can either be left unsprayed or sprayed at low threshold.

(1975) did not regard it as part of the "ununguis complex". Bayer computer code: OLIGPD EPPO A1 list: No. 217 EU Annex designation: II/A1 HOSTS All known host plants are conifers, mainly of the family Cupressaceae: Chamaecyparis pisifera, Juniperus chinensis, J. formosana, Thuja orientalis. Taxus cuspidata and Cryptomeria japonica have also been recorded as hosts. In a glasshouse environment, the mite was successfully reared on J. communis, J. x media, J. sabina, J. virginiana and Thuja orientalis. GEOGRAPHICAL DISTRIBUTION EPPO region: Netherlands (intercepted only). Asia: China (Ma & Yuan, 1976), Hong Kong, Japan (Hokkaido, Honshu), Korea Republic (Lee et al., 1989), Taiwan (Lo & Ho, 1989).

BIOLOGY No research has been done on biological or ecological features of O. perditus such as reproduction rate, predators or overwintering capacity. These are most likely to be comparable with those of O. ununguis. On intercepted bonsai material of J. chinensis in the Netherlands, O. perditus overwintered in the egg stage, as O. ununguis does also. In Japan, diapause was induced in O. ununguis by the influence of two factors: day length and food supply.

In Europe, it is an indige- nous species, commonly found on various plants, including conifers. The present study examined whether A. andersoni can develop and reproduce while feeding on two key pests of ornamental coniferous plants, i.e., Oligonychus ununguis (Jacobi) and Pentamerismus taxi (Haller). Pinus sylvestris L. pollen was also tested as an alternative food source for the predator. Both prey species and pine pollen were suitable food sources for A. andersoni. Although higher values of population parameters Citation: Puchalska, E.; were observed when the predator fed on mites compared to the pollen alternative, we conclude that Zagrodzki, S.K.; Kozak, M.; pine pollen may provide adequate sustenance for A.

  • Spruce Spider Mite
    2/16/2021 Spruce Spider Mite HOME | SPRUCE SPIDER MITE Spruce Spider Mite The spruce spider mite attacks spruce, arborvitae, juniper, hemlock, pine, Douglas-fir, and occasionally other conifers. ARTICLES | UPDATED: MARCH 23, 2017 Oligonychus ununguis (Jacobi) Introduction The spruce spider mite is considered one of the most destructive spider mites in the United States. It injures the foliage of spruce, arborvitae, juniper, hemlock, pine, Douglas-fir, and occasionally other USDA Forest Service - Region 4 - Intermountain, USDA conifers. Dwarf Alberta Forest Service, Bugwood.org spruce, Picea glauca 'Conica', is one of this pest's preferred host plants. Description After hatching, the young, pale green mites called larvae resemble adults except they are smaller and have only three pairs of legs. As the mites mature, they shed their skins three times before becoming adults. Adults and nymphs have four pairs of legs and are dark green to nearly black with the body surface clothed with salmon pink-colored spines (Fig. 1). The adult's legs are also salmon pink. https://extension.psu.edu/spruce-spider-mite 1/3 2/16/2021 Spruce Spider Mite Life History This key pest overwinters as brown eggs tucked in and around bud scales and at the base of needles. These hatch in the spring, usually before new growth starts. A generation from egg to adult may require 15-20 days and generations frequently overlap so that all stages may be found on host plants during late spring and early summer. There are 7-10 generations produced each year. Damage This species damages host plants by sucking plant fluid from needles as they feed.

  • Development Durations, Colonization and Insecticide Efficacy of Leaf Mite, Oligonychus Oryzae Hirst on Rice
    Tropical Agricultural Research Vol. 21(1): 30 - 38 (2009) Development Durations, Colonization and Insecticide Efficacy of Leaf Mite, Oligonychus oryzae Hirst on Rice V. Radhakrishnan and K. Ramaraju Department of Agricultural Entomology Tamil Nadu Agricultural University Coimbatore 641 003, Tamil Nadu India ABSTRACT. Oligonychus oryzae is an economic mite pest infesting rice crops in India and other Asian countries. This study examined the duration of development instars at 20 °C – 35 °C , level of colonization of mites in eight commercial rice varieties viz., ADT 36, ADT 43, ADT 45, IR 50, CO 47, ASD 16, ADTRH 1 and TN 1 and assessment of efficacy of five insecticides against O. oryzae during 2005 and 2006. The duration of development from egg to adult lasted 8.33±0.20 days at 35 °C. ASD 16, ADTRH 1 and CO 47 were moderately resistant to leaf mite; ADT 45, TN 1, IR 50 and ADT 36 were moderately susceptible; ADT 43 was the most susceptible variety. Among the chemicals tested, Abamectin 1.8 EC was found to be the most effective. INTRODUCTION Rice, Oryza sativa L., supplies food for nearly half of the world’s population. The crop is extensively cultivated in South and South East Asian countries. Rice crop is the foundation of national stability and economic growth in many developing countries including India. In India, the average productivity of rice is 2.11 tonnes per hectare (Viraktamath and Shobha 2008). Among the arthropod pests, insects are considered as the major pest group threatening rice production. In recent years, mites have become a greater concern to the successful cultivation of rice in India, particularly South India.

  • Spruce Spider Mites
    Spruce Spider Mites TREE DOCTOR TIPS Spruce Spider Mites (Oligonychus unuguis) description: Ranging in color from green to orange-red, spruce spider mites are conifer-loving pests that overwinter as orange eggs at the base of needles and twigs. After hatching and molting several times, the adults mate and lay eggs. There can be six to eight generations each season, depending on temperature. The spruce spider mite is most active during the cooler temperatures of spring and fall, and may discontinue its feeding and reproductive activity when temperatures rise during the summer months. hosts: a Spruce spider mites feed on more than 40 different types of conifers, especially Alberta spruce, as well as arborvitae, fir, hemlock, juniper and other spruce species. biology and symptoms: These sap-sucking pests deprive trees of nutrients, causing their needles to fleck and turn yellow. Signs of a worsening infestation include remnants of silk webbing and shed skins, as well as brown needles, premature needle drop, and branch or tree death. management: b Unless treating sensitive dwarf Alberta spruce or Colorado figure a. spruce spider mites, webbing on spruce spruce, apply an appropriate miticide before bud break to figure b. eggs of the spruce spider mite, close-up reduce overall populations and again in late fall if necessary.

  • On Lychee Valter Arthur1,2,*, and André R
    Development of phytosanitary irradiation against Aceria litchii (Trombidiformes: Eriophyidae) on lychee Valter Arthur1,2,*, and André R. Machi1,2 Abstract The lychee erinose mite, Aceria litchii (Keifer) (Trombidiformes: Eriophyidae), is the most important pest of lychee (Litchi chinensis Sonn. (Sapindales: Sapindaceae) in parts of China, India, Southeast Asia, South Africa and Brazil. This study sought to develop the basis for phytosanitary irradiation of lychee to provide quarantine security against this pest. New methodology had to be devised for this purpose because the adult, the largest life stage—about 200 µ long—cannot be seen without magnification, and because this species does not survive more than a few d even on detached young lychee leaves, or under other artificial conditions. Initially we adapted a method devised by Azevedo et al. (2013) for keeping the adults alive long enough to evaluate the lethal effects of candidate acaricides for at 48 h post treatment. We collected infested leaves from a lychee orchard and irradiated then with doses increasing by increments of 200 Gy in the range 0–2,000 Gy. Each infested leaf had 30 to 40 adult mites. Each of 3 replicates involved ~816 adult mites and ~2,450 adult mites per treatment. Because of the presence of predators hidden within the erinea, we col- lected 30 adult mites per replicate immediately after irradiation, and placed them in a 14-cm-diam petri dish with a new young lychee leaf and moist cotton. We covered each petri dish with parafilm® to prevent escape of mites and loss humidity. At 24, 36, and 48 h post irradiation, we counted the numbers of live and dead mites.

Title: Distribution of OliRonvchus (OliRonvchus) ununzuis (Jacobi) (Acari: Tetranvchidae) and Predator Mite Snecies (Acari: Phvtoseiidae) on Field-Grown Douelas-Fir (Pseudotsura menziesii [Mirb.l Franco) Christmas Trees Redactedfor Privacy Abstract approved. Jack DeAngelis Redacted for Privacy Abstract approved_ I/Glenn Fisher The shake and wash technique (samples placed in a jar with alcohol added and shaken to remove the mites) was effective in removing 100% of the predator mites, and adult spruce spider mites from Douglas-fir foliage and 98% of the spruce spider mite nymphs. Eighty-eight percent of the spruce spider mite eggs was removed. This technique was considered efficient for removal of spruce spider mite and its predators from Douglas-fir foliage. Sodium hypochlorite (0.84%) added to the alcohol did not increase the number of spruce spider mites or phytoseiid mites removed from the foliage. The intracanopy distribution of spruce spider mite and its predator mites was studied on Douglas-fir Christmas trees in the Willamette Valley, Oregon. When overwintering spruce spider mite egg densities populations were low (<5 eggs/19 cm of stem), significantly more eggs were found on the current season's growth. No significant differences were found between top and bottom halves of the tree or between compass directions. Differences between current and previous season's growth were not found when egg densities were high (>40 eggs/19 cm of stem), but significant differences were found between levels for current season's growth with more eggs found in the upper portion of the canopy.Quadri-directional differences did not exist with either low or high mite populations.
