Read More Phytonemus pallidus (Banks) reported for first time from New York in 1898. At present, cyclamen mite has a worldwide distribution on cultivated strawberry plant in different states of USA, South American countries, Japan, Taiwan, Korean republic, South Africa and European countries like The Netherland and Turkey (Denmark, 2016). Host ranges of cyclamen mite has been reported on African violet, begonia, gerbera, ivy, chrysanthemums, geranium, fuchsia, larkspur, petunia, snapdragon (Denmark, 2016).This mite is exotic pest to strawberry plants in Iran. For the first time this mite found on Parvous, Queen Eliza, Kurdistan, Aromas, Camarosa, and Selva strawberry varieties in Kurdistan province of Iran (Kamangar et al., 2016). After that, the mite also collected on different weed species such as Senecio sp., Lamium amplexicaule, Polygonum lapathifolium, Amaranthus sp., Plantago sp. Sencio vulgaris, Veronica persica and Malva sylvestris in Kurdistan province (Mansour Ghazi, 2018). The first invasive cyclamen mite damages on greenhouse strawberry observed on sabrina and camarosa varieties in range of 16-22 degree Celsius and above70% relative humidity during autumn season in several greenhouses of strawberry in Hashtgerd vicinity of Alborz province. Developmental stages of this mite consist of egg, larvae, pharate female, adult male and female. Male and female of cyclamen mite easily distinguished through fourth pair of legs which tarsus of male terminated with strong claw, used for holding and carry pharate female stage for mating while tibia and tarsus segments of fourth pair of legs in female, combined together ending with two long and short setae. Color of larvae and pharate female are whitish whereas female and male changed into yellowish color. The main damages of cyclamen mite caused by injecting toxin to newly emerged leaves, petioles of leaf, sepal of flower, changing color of infested plant parts into brown, reduce growth, protect fruit formation and death of infested plants finally. Sometimes, these symptom of injuries initially may confused with phytoplasma diseases on strawberry plants. Results of biological control studies of cyclamen mite by two phytoseiid predatory mites (Neoseiulus californicus (McGroger), N. cucumeris (Oudemans) revealed that, 76% control achieved on active P. pallidus stages only (Easterbrook et al., 2001). Most of sign of cyclamen mite injuries observed around heating system and hot air blowing direction on Camarosa and Sabrina strawberry varieties in the greenhouses in Hashtgerd vicinity of Alborz province. Free strawberry seedling from cyclamen mite infestation protect cultivated plants from further severity mite damages during growing and harvesting periods.

Read More Fruit russeting is one of the important symptoms affecting marketing of apple (Malus × domestica Borkh.) fruits. The study had been conducted in Semirom region, Iran, in 2019 showed that one of casuals of fruit russeting is stem-end russeting caused by yeast-like fungi Aureobasidium sp. (Heidarian et al., 2020). Easterbrook and Fuller (1986) reported apple rust mite, Aculus schelchtendali Nalepa (Acari: Eriophyidae) as a causative of russeting on apple fruits. In some orchards of Semirom region, in addition to two common cultivars (Red Delicious and Golden Delicious), several other cultivars (including Golab-e-Isfahan, Golab-e-Kohanz, Miracle, Granny Smith and Fuji) were also cultivated. Miracle is one of the apple cultivars was recently introduced to the country and its cultivation area has been increased. This cultivar has export value and a high marketability due to its desirable color. During the study on the causative agents of fruit russeting in 2017 and 2018, some rusted fruits of Miracle cultivar were found, with similar symptoms to apple rust mite. Infested leaf and fruit samples were collected, and their microscopic slides were prepared in the laboratory after clearing the mites. To check possible infestation of different apple cultivars to the mite, their leaf and fruit samples were collected and compared with the typical symptoms of its damage. Specimens of the mite were identified by the third author as Aculus schlechtendali Nalepa (Acari: Eriophyidae). In Iran, apple rust mite was reported firstly by Sadeghi Nameghi (1995) from Mashhad on apple leaves. However, this is the first report of the mite as the causing agent of fruit russeting in Iran. Examination of the infested fruits showed that the damage appears as russeting around the calyx which gradually covers the entire surface of the fruit to varying degrees. Moreover, feeding of the mite on underside of the leaves causes browning of the leaves in summer (Figure 1). Generally, damage intensity and fruit russeting from apple rust mite is related to population density of the mite, cultivar and plant age (Easterbrook and Fuller, 1986). In the present study, damage of apple rust mite was found only on Miracle cultivar. Regarding increasing of cultivation area of this cultivar in some apple orchards around the country, it is necessary to be careful for possible increase of population density of apple rust mite, because the mite, in addition to direct damage, could reduce marketability of the cultivar, due to the occurrence of fruit russeting.

Read More Strawberry, Fragaria ananassa Duch. which belongs to the Rosaceae family is one of the most important micro-fruits of temperate regions that has been considered as one of the most important and commercial products in the recent decades. Golestan province is the third largest strawberry producer in Iran after Kurdistan and Mazandaran Provinces (Ahmadi et al., 2018). Spodoptera littoralis (Boisduval, 1833) is a highly polyphagous pest that attacks to a wide range of crops (Lanzoni et al., 2012). The eggs are whitish-yellow in color, spherical, somewhat flattened, with 0.6 mm diameter, surrounded by hair scales. The newly hatched larvae are 2 to 3 mm long with white bodies and black heads and are very difficult to detect visually. The larvae are hairless, cylindrical, and variable in color from blackish-gray to dark green, becoming reddish-brown or whitish-yellow. They have dark and light longitudinal bands on lateral sides; and with two dark semilunar spots on each segment (except for the prothorax) dorso-laterally. This pest has 5-6 larval instars, and length of full grown larvae is 40-45 mm. The pupae are cylindrical, 14-20 5 mm, and the last segment ends in two strong straight hooks. Firstly in green with reddish color on the abdomen, turning dark reddish-brown within few hours. The adult moth with length of 15-20 mm, and wingspan of 30-38 mm. It has a gray-brown body, with gray to reddish brown forewing that has paler lines along the veins, and grayish white hind wing, iridescent with gray margins (Pinhey, 1975).Based on the available literature, the larvae ofS. littoralis are newly observed in Golestan Province on strawberry (Fig. 1). In the early stages of damage, the young larvae feed on small areas on the underside of the leaf. Older larvae make large holes in the leaves or eat them completely, or damage young branches, young buds and bare parts of the stems, severely. In the Khan Bebin fields where strawberry bushes left in the ground to produce stolons for reproduction, the larvae started to feed on the leaves from the early September, and with increasing the larval age, their feeding intensified and eventually caused destroying the central meristem of the plant. Egyptian cotton leaf worm with its high ability of reproduction, and feeding, can be considered as a serious and very important pest in Golestan province, due to the climatic conditions of the region.
