There are various species of thrips
, but the most common are thrips
tabaci and the western flower thrips
The major insect pests of cotton such as thrips
tabaci (Lind.); jassid, Amrasca devastans (Dist.); whitefly, Bemisia tabaci (Genn.); aphid, Aphis gossypii (Glav.); mite, Tetranychus cinnabarinus (Boise); spotted bollworm, Earias insulana (Boise); pink bollworm, Pectinophora gossypiella (Saund) and American bollworm, Helicoverpa armigera (Hub.) .
were seen in more numbers on flowers floral parts as compare to leaves, because it gives shelter from weather condition and help to escape from natural enemies.
Highest and lowest numbers of dusky bug were found on IUB-33 and MNH-988, while mites' population was noted highest on Sitara-009 and lowest on IUB-33, whereas population of white fly was recorder highest on IUB-33 and lowest on NIAB non-Bt, on the other hand thrips
were highest on NIAB non-Bt and lowest on Sitara-009 (Supplementary Table III).
and mites found were slide-mounted for identification (MOUND; MARULLO, 1996; KRANTZ; WALTER, 2009).
The highest densities of thrips
were observed during the vegetative stage, while the densities were intermediate during flowering, and lowest in the fruiting plants (Fig.
This study assessed the diversity of thrips
in restinga remnants in the state of Ceara, Brazil, as an attempt to foster research on thrips
in the Brazilian Northeast.
The less thrips
damage caused on some cultivars could be due to the presence of toxic metabolites and/or to the absence or suboptimal amounts of some essential nutrients available to the insects (Saxena, 1985).
The study was performed in Dystrophic Red Yellow Argisol (Ultissol), where the hybrid known as Exceler was used in order to verify the behavior of the thrips

The pooled data clearly indicated that the population of thrips
before initiation of spray was uniform with a range of 9.23 to 9.42 per leaf (Table 4).
of Aphid, Thrips
(1) and armyworm (1) were witnessed.

Control by Crop (Fruits, Vegetables & Flowers), Formulation (Liquid, Water-dispersible Granules, Wettable Powder & Pellets), Active Ingredients (Predators, Parasites & Biorationals), and by Region - Global Forecasts to 2020
(Thysanoptera) are pests of many cultivated plants in Brazil, and at least one forage crop and 13 ornamentals are attacked by these insects.
