  author={Roopa S. Patil},
Investigations on mite pests of solanaceous vegetables were carried out during 2003-2005 at the University of Agricultural Sciences, Dharwad. Among the three phytophagous mites recorded on brinjal, Tetranychus macfarlanei Baker and Pritchard was most predominant. The natural enemies comprised of three predatory mites and four insect predators. Polyphagotarsonemus latus Banks was recorded on chilli and potato as major pest. In brinjal, spider mite population reached peak twice i.e. in middle of… 
Seasonal incidence and management of tetranychid mites in brinjal
Results of survey on tetranychid mites in three districts covering four taluks carried out during 2006-07 revealed the highest pest incidence in Dharwad taluk and the lowest in Mundagod taluk of Uttara Kannada district, with analysis of yield and net return indicated that neem oil and NSKE recorded higher yield and maximum net returns.
Incidence of Tetranychus urticae Koch on brinjal under field and screen house conditions
The results clearly showed that 5.19 and 5.85 mites/sq cm leaf T. urticae population peak in the last week of September 2014 on brinjal plant under field and screen house conditions, respectively.
Seasonal incidence and management of red spider mite , Tetranychus urticae Koch on Okra , Abelmoschus esculentus ( L . )
The pooled data on bio-efficacy of certain acaricides and botanicals against okra mite was recorded after two spray and revealed that Abamectin was found to be the best treatment in reducing the mites population.
Novel acaricide molecules for the management of rice leaf mite, Oligonychus oryzae (Hirst) (Acari: Tetranychidae), an emerging pest of rice in Kerala
Efficacy of wettable sulphur (89-95%), was also found to be on par with the novel molecules, however, the efficacy of botanicals was inferior to dicofol.
Damage potential of Tetranychus urticae Koch to cucumber fruit and foliage: Effect of initial infestation density
Highly significant negative correlation was recorded between mite population and photosynthetic pigments and the cumulative effect led to the ultimate reduction in average fruit weight in the range of 10.16 to 17.19 per cent in the infested plants.
Status of acaricide resistance in field collected two-spotted spider mite, Tetranychus urticae Koch from vegetable growing areas of Punjab, India
Fenpyroximate was found to be the most toxic against all the tested populations except Malerkotla population, and low to moderate levels of resistance (3.19-24.65 fold) was reported in T. urticae to tested acaricides in Punjab.
Evaluation of selected acaropathogenic fungi, botanicals and new acaricide molecules against Tetranychus urticae Koch (Prostigmata: Tetranychidae) on okra
The study identified three novel acaricide molecules for the effective management of T. urticae though the bio-agents and botanicals did not give consistent results during the two seasons of study.
Bio-Efficacy, Yield Loss and Economics of Two Spotted Spider Mite Tetranychus urticae Koch (Acarina: Tetranychidae) Management through Synthetic Acaricides and Biorationals in Grape Vineyards
A study on the bioefficacy of synthetic acaricides and selected biorationals was conducted in Karnataka (India) for management of Tetranychus urticae infesting grapes and hexythiazox appeared to be highly effective in containing the incidence of grape mites.
Efficacy of Insecticides on Mites in Grape
Grape (Vitis vinifera L.) is one of the most important fruit crops of temperate zone which has acclimatized to tropical and sub-tropical agro climatic conditions. Grape is fairly good source of
Ovicidal and adulticidal effect of acaropathogenic fungi, neem oil and new acaricide molecules on Tetranycus urticae Koch
The relative toxicity of two acaropathogenic fungi, neem oil and three new acaricide molecules to two-spotted spider mites (egg and adults) were evaluated against a standard check and untreated control under laboratory conditions and fenazaquin 10 EC excelled in ovicidal activity with a mean egg mortality of 40.81 per cent.


Occurrence and succession of pests of brinjal, Solanum melongena Linn. at Gwalior (Madhya Pradesh), India.
The pest complex of brinjal monitored during summer and kharif 1993 seasons at Gwalior, (Madhya Pradesh) included 6 hemipterous, 3 lepidopterous, 2 coleopterous and 1 acarina pests. The jassid,
Experimental trials were undertaken to study the impact of fertilizers on the population build- up of thrips and mites on chilli crop, an important spice crop in India.
Chemical control of red spider mite (Tetranychus cucurbitae Rahman and Sapra) on Brinjal.
Following a severe outbreak of Tetranychus neocaledonicus Andre on brinjal [Solanum melongena] near Hissar in the Indian State of Haryana in February 1972, 19 chemicals were tested for the control of this mite and the effectiveness of dimethoate and phosphamidon, which had previously given good results against T. neocalingonicus, was confirmed.
Contribution to the Study of some Phytophagous Acarina and their Predators in Mauritius
During investigations on the phytophagous mite fauna of Mauritius, 21 species were collected, of which ten species belong to the TETRANYCHIDAE, only two predatory mites of great economic importance are recorded, and results are given of a survey of the predatory insects associated with the phyllocoptruta oleivora and Tegonotus.
Pest complex of egg plant (Solanum melongena) and their succession at medium high altitude hills
The studies on pest complex and their succession conducted during 1994-95 at Barapani, Meghalaya revealed that twenty seven insect pests and four non - insect pests were recorded to infest the
Mites Injurious to Economic Plants
In this timely volume the authors provide an authoritative digest of all the available information on the mites (Acarina) known to produce injury to plants of economic importance. They review our
Effect of Different Host Plants and of Season on Tolerance of the Carmine Spider Mite to Malathion
Mites reared for three weeks on castor beans were consistently more susceptible to malathion than mites rearing on control plants, and mortality in May was at least twofold higher than in September.
Acaricidal Tests of Nine Pesticides Against the Two-Spotted Spider Mite, a Serious Pest of Brinjal (Eggplant) in West Bengal
Though wettable sulfur is the cheapest material for the control of mites alone, carbophenothion appears to be most economical, as it is effective against a wide range of pests associated with the mite.

In order to make experimental studies comparable and statistically meaningful, the article recommends the following formula: per cent control = 100(X - Y)/X, which eliminates errors due to deaths in the control sample which were not due to the insecticide.
