Sublethal effects of spirodiclofen on the demographic parameters of Tetranychus urticae Koch (Acari: Tetranychidae)

Archives of Phytopathology and Plant Protection, 2019
The two-spotted spider mite, Tetranychus urticae Koch is one of the most common pests of agricultural crops. The use of sublethal doses can reduce the need of pesticides and prevent pests’ resistance, which is an important step in integrated pest ...

Ontogenetic development and redescription of Tribolonychus collyerae (Acari: Tetranychidae) 

Zootaxa, 2013
Tribolonychus collyerae Zhang & Martin is redescribed based on the larva, protonymph, deutonymph and adult male and female specimens from New Zealand. The ontogenetic development of chaetotaxy in Tribolonychus and the number and position of solenidia on tibia I are discussed.

Population Dynamics of Tetranychus Kanzawai (Acari: Tetranychidae) on Hydrangea

Experimental & Applied Acarology, 2000
The seasonal occurrence of Tetranychus kanzawai Kishida populations on hydrangea (Hydrangea macrophylla) was studied at two different localities in Ibaraki, Japan, during a three-year period. There were two types of seasonal population trends: one with a population peak from May to June, and the other with the spring peak in June and the autumn peak in

Ontogenetic development and redescription of Eotetranychus kankitus (Acariformes: Tetranychidae)

Zootaxa, 2018
Eotetranychus kankitus Ehara, 1955 is redescribed from females, males, deutonymphs, protonymphs and larvae collected on Citrus reticulata Blanco (Rutaceae) from China. The ontogenetic changes in leg chaetotaxy are provided and compared with the similar species Eotetranychus tiliarium (Hermann, 1804) and the considerably hypotrichous species ...

Die Carbohydrasen der SpinnmilbeTetranychus urticae Koch (Acari, Tromb{ie307-1}diformes, Tetranychidae)diformes, Tetranychidae)

Experientia, 1961
In preparations of crushed whole spider mites (Tetranychus urticae Koch), the enzymes capable of hydrolyzing carbohydrates were identified. The products of the enzymic hydrolysis were detected by paper chromatography. The following substrates were hydrolyzed: Starch, maltose, sucrose, trehalose, melibiose, lactose, melezitose and raffinose.
