Life Cycle and Description. However, due to its high reproductive capacity, strong adaptability and short life cycle, T. cinnabarinus has developed resistance to these acaricides rapidly, thus making the control even more difficult . Life table parameters, including net reproductive rate (R 0), mean generation time (T), doubling time (DT), finite rate of increase (λ), and intrinsic rate of natural increase (r m) have been used to evaluate the susceptibility or resistance of several host plants in relation to various pests (Tsai and Wang, 2001, Satar and Yokomi, 2002, Razmjou et al. This is another reason for the rapid development of pesticide resistance in T. cinnabarinus. distribution and is present on all major Hawaiian Islands. Silica gel column chromatography was used to further separate acaricidal components from I. japonica petroleum-ether extracts. Deltamethrin-selected and omethoate-selected mites both had higher net reproductive rate (R 0), intrinsic rate of increase (r m "pockets" often near the midrib and veins. This mite has developed resistance to at least 25 pesticides in China. The carmine spider mite has The life cycle was 12.8 days for females and 11.7 days for males at 25°C; while at 30°C, it was 7.2 days for females and 6.2 days for males. Its life cycle consists of eight stages from egg to adult, including three quiescent stages of insensitivity to miticide. However, the acaricidal mechanism of scopoletin remains unclear. 2011). Figure 4. Prey Preference and Life Table of Amblyseius orientalis on Bemisia tabaci and Tetranychus cinnabarinus. Males have a shorter life span than females (Mo and Liu 2007). Adults live for about 12-14 days, and on average, a single female lays about 33 eggs in its life span at the rate of 3.2 eggs/oviposition day.

Service, College of tropical Agriculture, Insect Pest Series No. This species is very similar in general ap-pearance to Tetranychus cinnabarinus. Pesticide resistance may be managed by rotational use of pesticides, biological control and other methods. The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a widespread agricultural pest, causing severe damage on a variety of greenhouse and field crops (Cranham 1985).Spider mites are difficult to control with pesticides (Nahar et al. Tetranychus cinnabarinus (Boisduval) Tetranychus telarius (Linnaeus, 1758) Common Names. Key … Under optimum conditions (approximately 80ºF), spider mites complete their development in five to twenty days. Larvae are slightly larger straw colored, and hatch in 3 days. The bearing of these results on the cultural control of some spider mite populations by very high humidities is discussed. Legs are often dark red as well.

Carmine Spider Mite. The males 3. feeds on all stages of these mites and in laboratory conditions The spider mite, Tetranychus cinnabarinus (Biosduval) has assumed the status of major pest and caused 17.46 per cent yield loss in okra (Sarkar et al., 1996). effective as Stethorus. 100 cultivated crops and weeds. The second species (T. cinnabarinus), which is dark reddish-brown, has a similar life cycle to T. urticae, but does not hibernate. Eggs are spherical, shiny, pesticide-resistant: life cycle becomes shorter and reproductive rate becomes greater. 501-502. Their life cycle comprises egg, larva, protonymph, deutonymph, and adult stages, and feeding by larvae in some species is facultative. These mites are also difÞ-cult to control due to their resistance to many com-monly used pesticides (Cranham and Helle 1985, Grosscurt et al. They are only about 1/254inch in diameter. 2002).

Both two-spotted spider mites and flat mites have five life stages: egg, larva, protonymph and deutonymph (or nymphs), and adult. The sex ratio is about 1:1. The life cycle was 12.8 days for females and 11.7 days for males at 25°C; while at 30°C, it was 7.2 days for females and 6.2 days for males. The nymphal stage differs Sherman. Species survey of spider mites and seasonal occurrence of Thrips palmi, Chlorita biguttula biguttula, and Tetranychus cinnabarinus on eggplant. The greatest net multiplication rate per generation (R0 ) is at 24°C and 38 % RH. However, the high reproductive potential and extremely short life cycle of these mites, result in rapid resistance development to many acaricides often after only a few applications, which is a major problem for the control of T. cinnabarinus (Devine et al., 2001; Stumpf & Nauen, 2001). In this study, we aimed to identify acaricidal compounds in Inula japonica against Tetranychus cinnabarinus. Based on results of the present study, we believe it is valuable to evaluate strategies with releases of a specialist predator of T . than the egg, pinkish, and have three pairs of legs. The second species (T. cinnabarinus), which is dark reddish-brown, has a similar life cycle to T. urticae, but does not hibernate. The major natural predator The life cycle (egg-to-adult) of these mites varies from less than a week under summer conditions to 10-18 days during winter, with the broad mite developing more quickly than the cyclamen mite. ...
