“…The primer sequences for around 10 SSR markers are publicly available for studying the genome of the spiralling whitefl y (Ma et al, 2011). SSR markers are used in the analysis of genetic divergence and geographical distribution of A. dispersus (Boopathi et al, 2014(Boopathi et al, , 2017b. Earlier, the SSR markers were utilized for studying the genetic diversity of B. tabaci and differentiating the variants of B. tabaci and determining the genetic relationships of closely related populations (Gawel & Jarrett, 1991;De Barro et al, 2003;De Barro, 2005;Delatte et al, 2006;Tsagkarakou et al, 2007;Gauthier et al, 2008;Diaz et al, 2015).…”

“…The range in the susceptibility of crops has been catalogued for India (Andaman Nicobar, Andhra Pradesh, Himachal Pradesh, Karnataka, Kerala, Manipur, Meghalaya, Mizoram, and Tamil Nadu) by Ranjith et al (1996) and Boopathi (2013). Banana, castor, chili, citrus, cocoa, coconut, cashew nut, eggplant, guava, jack fruit, okra, papaya, pea pigeon, pepper, sapota and tomato are breeding and feeding hosts for A. dispersus (Srinivasa, 2000;Boopathi, 2013;Boopathi et al, 2014).…”

“…The spiralling whitefl y, Aleurodicus dispersus Russell (Hemiptera: Aleyrodidae: Aleurodicinae) was fi rst reported in 1993 at Thiruvananthapuram (Kerala, India) on cassava (Palaniswami et al, 1995) and has spread across Southern and North-eastern India since 1993 and has subsequently become a major pest of agricultural and horticultural crops (Srinivasa, 2000;Boopathi et al, 2013Boopathi et al, , 2015a. This species was possibly introduced into India from neighbouring countries like Sri Lanka (Ranjith et al, 1996), Maldives (Muniappan, 1996) and Myanmar (Boopathi, 2008;Boopathi et al, 2014). The spiralling whitefl y has had a dramatic negative effect on the agricultural industry and resulted in signifi cant monetary losses (Alam et al, 1998).…”

http://www.eje.cz whitefl y populations to the host plants. Geetha (2000) and Boopathi (2013) report that the fecundity, egg hatchability, incubation period, total developmental period, pupal period, percentage adult emergence, sex ratio (female : male) and adult longevity varies on the different host species. Mayer et al. (2010) report that the type and level of damage varies depending on the species and condition of the plant. Dense populations of this polyphagous pest causes premature leaf drop and the honeydew they produce serves as a substratum for the growth of sooty mould, leading to the crops being abandoned (Akinlosotu et al., 1993; Boopathi et al., 2014). A four month long infestation of guava by A. dispersus can result in 80% fruit yield loss (Wen et al., 1995). Banana production is also reduced by an A. dispersus infestation (Ranjith et al., 1996). A. dispersus is also one of the yield limiting factors in cassava cultivation

“…The Eastern Himalayas of India is unique in its agro-ecosystems, and consequently the insect pest problems are also distinct from the rest of the country. Pest problems in the region are innumerable and as many as 6,000 species of insects have assumed pest status on various crops over the decades (Boopathi et al 2014). Tomato, Solanum lycopersicum L. (Solanaceae), is one of the most important vegetable crops in the Eastern Himalayas of India.…”

Insect infestation can adversely affect tomato (Solanum lycopersicum L.; Solanaceae) development and yield. Fruit flies (Diptera: Tephritidae) are a serious pest of tomato, and are spreading to areas where they were not previously found. This study was undertaken to determine if tephritid fruit flies were present, which species were most abundant, how tomato cultivars responded, and what amount of damage occurred in the Eastern Himalayas of India during May 2014 and 2015. Mature and ripe fruit (n = 20) per cultivar were picked at random from 12 cultivars at weekly intervals to assess percentage of infestation, fly species composition, larval infestation, pupal mortality, adult emergence, and sex ratio during 2 seasons. Seasonal fluctuation of male adults of Zeugodacus tau (Walker) (Diptera: Tephritidae) in tomato was studied by installing 3 modified clear traps, made from plastic bottles, that were baited with 0.5 mL Cue-lure and the insecticide dichlorovos 76% EC (Nuvan®). Survey and subsequent identification confirmed the presence of Z. tau in tomato in the Himalayas of India. This is the first report of the insect in the province, and of population outbreaks resulting in serious damage to tomato in India. Among fruit fly species present on tomato, Z. tau was more abundant (71.4-96.4%) in all geographical regions of Mizoram, India, than were Bactrocera correcta (Bezzi), B. dorsalis (Hendel), and B. latifrons (Hendel), which ranged from 3.6 to 28.6%. The highest percentage of infestation was in Champhai (72.7 ± 6.7%) and Kolasib (80.7 ± 3.5%) and the lowest in Mamit (14.7 ± 4.8%) and Serchhip (19.3 ± 4.7%). Cultivar influenced pupal mortality and adult emergence of Z. tau. Seasonal fluctuation of Z. tau males on tomato varied; the greatest numbers were trapped during May and Dec. Occurrence of Z. tau at high population densities was associated with high levels of damage and could lead to high economic losses in tomato fruit production.

“…Therefore, these studies clearly indicate that, besides the availability of new flowers and shoots, weather factors also play an important role in the T. papillosa incidence. The population buildup of any insect is very intimately associated with the weather factors prevailing during preceding and corresponding periods ( Boopathi et al. 2014 ).…”

The most destructive enemy of the lychee, Litchi chinensis Sonn. (Sapindales: Sapindaceae), in India is a stink bug, Tessaratoma papillosa (Drury) (Hemiptera: Tessaratomidae). The population of T. papillosa on lychee trees varied from 1.43 ± 0.501 to 9.85 ± 3.924 insects per branch in this study. An increase in the temperature and a decrease in the relative humidity during summer months (April to July) favor the population buildup of T. papillosa. A forecasting model to predict T. papillosa incidences in lychee orchards was developed using the autoregressive integrated moving average (ARIMA) model of time-series analysis. The best-fit model for the T. papillosa incidence was ARIMA (1,1), where the P-value was significant at 0.01. The highest T. papillosa incidences were predicted for April in 2010, January in 2011, May in 2012, and February in 2013. A model based on time series offers longer-term forecasting. The forecasting model, ARIMA (1,1), developed in this study will predict T. papillosa incidences in advance, thus providing functional guidelines for effective planning of timely prevention and control measures.
