Helopeltis theivora Waterhouse (Heteroptera: Miridae) or the tea mosquito bug (TMB) is a major sucking pest of tea (Camellia sinensis L.) in most tea-producing countries. The nymphs and adults of the TMB suck the sap from tender leaves, buds and young shoots, which results in heavy crop losses. The damage to tea plants caused by the TMB is not limited to the sucking of plant materials and extra-oral digestion by salivation. Damage is also caused by the insertion of eggs into plant tissues… 
New hosts of tea mosquito bug, Helopeltis theivora Waterhouse on eggplant (Solanum melongena L.) and amaranth (Amaranthus sp. L.) from India
TLDR
The current observations on TMB highlight the first report of the pest on cultivated eggplant and amaranth, and warrants extensive and exhaustive pest surveillance and intensive scouting and monitoring mechanism for designing effective pest management solutions.
Role of host switching in the development of pesticide tolerance in Helopeltis theivora (Hemiptera: Miridae), the major pest of tea in India
TLDR
While comparing the biology of this pest on the primary host (tea) and the alternative host (D. repens) it was found that total developmental period was higher in the Duranta-reared population, along with significantly higher nymphal mortality and significantly less fecundity, possibly signifying that host switching can play a role in the development of tolerance of H. theivora against insecticides.
Beauveria bassiana: as a potential microbial biocontrol agent for tea mosquito bug, Helopeltis theivora Waterhouse (Hemiptera: Miridae) in Dooars and Darjeeling, India
TLDR
The BKN20 isolate could be commercialized as an alternative microbial insecticide to reduce the load of chemical insecticides in the tea ecosystem.
Comparative bioefficacy of Bacillus and Pseudomonas chitinase against Helopeltis theivora in tea (Camellia sinensis (L.) O.Kuntze.
TLDR
Bacterial chitinase can be utilized in eco-friendly pest management strategies and may contribute to reduce or eliminate the chemical pesticide use.
First Report on Heat Shock Protein Expression in Helopeltis theivora Waterhouse (Hemiptera: Miridae) in Response to Different Hosts
TLDR
It may be opined that the expression of HSP has a protective role in H. theivora during host switching when reared on in the primary host tea and its alternative host, Duranta.
Change in activity of detoxifying enzymes in directionally selected population of tea mosquito bug (Helopeltis theivora) (Heteroptera: Miridae) by an organophosphate insecticide
TLDR
Isozyme profiles of defence enzymes can be used as indices for identifying tolerance level in the field population of H. theivora, enabling tea planters to carry out rapid monitoring of the tolerance status of the pest populations, thereby providing a ready clue to choose an effective insecticide for pest management.
Pests of Indian Tea Plantations
TLDR
Insect and mite pests (arthropods) are the most destructive, resulting in 5%–55% crop loss in India, and information on diagnostic characters and spatial and temporal distribution of these pests with nature of injury caused by them to tea crop have been documented.
The Population Structure and Presence of Helopeltis bradyi on the Tea Plant Parts at Various Times During the Day
TLDR
Results showed that nymphs dominated the H. bradyi population structure, mostly present on tea shoots at upper leaf surface, and 88.14% in the afternoon, while the eggs were only found on tender internodes of shoots.
Efficacy of Beauveria bassiana (Bals.) Vuill. against Helopeltis theivora Waterhouse in tea
TLDR
Out of different treatments, results showed that IIHR strain of B. bassiana was recorded minimum adults as compared to untreated control but was at par with Azadirachtin 1000 ppm and commercial formulation B. Bassiana.

Relative susceptibility of tea mosquito bug, Helopeltis theivora Waterhouse and red spider mite, Oligonychus coffeae Nietner eggs to commonly used pesticides
TLDR
The data obtained in the present study may be used as a tool of IRM (integrated resistance management) strategies that can effectively control the pests in the initial stage itself (egg stage).
Development of Tolerant Traits in Tea Mosquito Bug (Helopeltis Theivora Waterhouse) (Hemiptera: Miridae) under Insecticide Stress
TLDR
A reduced efficacy of insecticides is revealed against conventional field populations of H. theivora, possibly due to the changed traits in the insecticide- stressed but tolerant populations of this major sucking pest of tea.
Neem-based integrated approaches for the management of tea mosquito bug, Helopeltis theivora Waterhouse (Miridae: Heteroptera) in tea
TLDR
Effective combinations and dose of the insecticides along with their formulations in controlling H. theivora have been presented and discussed and azadirachtin concentration and its dilutions are the major criteria for getting desired bioactivity.
Development of resistance to endosulphan in populations of the tea mosquito bug Helopeltis theivora (Heteroptera: Miridae) from organic and conventional tea plantations in India
TLDR
By the F5 generation, nymphal duration was higher and fecundity was lower in the endosulphan- selected strain than in the non-selected strain from a conventional plantation and the susceptible strain from an organic plantation, which has practical implications for insecticide resistance management of this important sucking pest of tea.
COMPARISON OF LIFE CYCLE TRAITS OF A HELOPELTIS THEIVORA WATERHOUSE (HETEROPTERA: MIRIDAE) POPULATION INFESTING ORGANIC AND CONVENTIONAL TEA PLANTATIONS, WITH EMPHASIS ON DELTAMETHRIN RESISTANCE
TLDR
The tea mosquito bug, Helopeltis theivora (Waterhouse), is an important economic pest of tea in India and selection using sublethal concentrations of deltamethrin resulted in a 5.19-fold increase in insecticide resistance ratio.
Hypersensitive reaction and anatomical changes of young tea leaf (Camellia sinensis, clone TV1) during feeding by tea mosquito bug (Helopeltis theivora Waterhouse: Hemiptera: Miridae)
TLDR
The maximal activity of tea mosquito bug is from May-September, coinciding with high temperature and ISSN: 2319-7706 Volume 2 Number 8 (2013) pp. 187-195.
Biology of the tea mosquito bug (Helopeltis theivora Waterhouse) on Chromolaena odorata (L.) R.M. King & H. Rob.
TLDR
H. theivora Waterhouse, pest of tea, is emerging as a commonly occurring major pest of cashew ( Anacardium occidentale L.) in recent times and its life cycle on their alternate hosts is studied for the first time to help management decisions.
Impact of environmental factors on infestation of tea leaves byHelopeltis theivora, and associated changes in flavonoid flavor components and enzyme activities
TLDR
Activity of phenyl alanine ammonia lyase generally decreased as a result of insect attack, which was significant in the United Planters Association of South India (UPASI) varieties, and a significant decrease in polyphenols was also obtained in UPASI varieties.
Variation of resistance to endosulfan in tea mosquito bug, Helopeltis theivora waterhouse (heteroptera: miridae) in the tea plantation of the Sub-Himalayan Dooars, northern west Bengal, India
TLDR
The results indicate that endosulfan should be avoided for managing endOSulfan resistance in H. theivora.
Fitness traits of insecticide resistant and susceptible strains of tea mosquito bug Helopeltis theivora Waterhouse (Heteroptera: Miridae)
TLDR
It is demonstrated that only certain fitness components in the resistant strains appear to be adaptively changed and lowered and all other parameters were not significantly different.
