scirtothrips dorsalis


Insects feeding in new growth limits and stunts overall plant growth, and may induce abortion of fruit. Posteromargnial seta II is 1.5 times longer and broader than posteromarginal setae I and III (Skarlinsky 2004). 125. Scirtothrips minutissimus (Bagnall) These characteristics increase the chance of transportation of Scirtothrips dorsalis through international trade of fresh plant materials.

Biological parameters of chilli thrips. This thrips has a rapid life cycle, and can develop from egg to adult in slightly less than two weeks under optimal weather conditions. It has most recently been reported in St. Vincent (2004) Florida (2005), Texas (2006), and Puerto Rico (2007). 25 - 33. Various biological control agents, including minute pirate bugs, Orius spp. Thrips as crop pests. Woo. [40][41] However, interceptions of this insect at a Miami port under the calyces of pepper from St. Vincent in 2003[40] inspired the USDA to act in order to predict and prevent the pest's arrival. Zootaxa 268: 1 - 40. Upon the establishment of Scirtothrips dorsalis in the Caribbean in 2003 there was a paucity of information for effective management of this insect with modern insecticides. 2008). Scirtothrips andreae (Karny) The two larval stages are completed in eight to ten days and the pupal stage lasts for 2.6-3.3 days. [44] It has been spotted several times on retail roses in south Texas, and anecdotal evidence suggests that the expansion into Texas counties is probably underreported. Bulletin of Entomological Research 79: 567578.

Proceedings of the Caribbean Food Crops Society 44. Many recommendations have been suggested by the World Vegetable Center (AVRDC) which could serve as basic management practices for this pest. Only one Beauveria bassiana product is registered as an insecticide in the United States. 2006b). [15][16][17] Colder temperatures may even drive pupation, but this has not been experimentally confirmed.

[41] By January 2007, the thrips had been found in more than thirty counties from Alachua to Monroe, and has been detected in southern Georgia. Lee, G.-S., J.-H. Lee, S.-H. Kang, and K.-S. Management practices include crop rotation, removal of weeds (which may serve as hosts), and supporting the maximum use of natural enemies, including predators and parasites, and rotating insecticides. pp 105-108.

Feeding on host plant by the chilli thrips, Scirtothrips dorsalis Hood, also results in softening of calyx which causes premature falling of fruits. Due to its diverse vegetation and subtropical climate, Florida is extremely suitable for the establishment of invasive alien flora and fauna (Ferriter et al. Mound. The forewings possess an incomplete second vein, or a row of setae with two or three irregular setae in the distal half and a complete first vein. doi:10.1371/journal.pone.0123747.

[20] Like many thrips, S. dorsalis appears to prefer feeding on new growth and young plants,[6][11][15] and is often found on the newer top leaves on smaller plants, although individual plant morphology and chemistry may result in some distributional differences.

In the United States, the chilli thrips, Scirtothrips dorsalis Hood, is a relatively new, introduced insect pest in Florida and Texas.

1982. Feeding damage can reduce the sale value of crops produced, and in sufficient numbers, kill plants already aggravated by environmental stress. This spelling has been preserved in the common name for the insect by entomologists in the United States in deference to the body of literature already published for this species by international authors.

Like all thrips of suborder Terebrantia, S. dorsalis undergoes two nymphal stages followed by two "false" pupal stages,[11] and under optimal conditions, this thrips may reach adulthood in approximately two weeks.

The chilli thrips[derivation 1] or yellow tea thrips, Scirtothrips dorsalis Hood, is an extremely successful invasive species of pest-thrips[1] which has expanded rapidly from Asia over the last twenty years, and is gradually achieving a global distribution.

Afinal, os pesticidas aprovados no Brasil esto proibidos em outros pases? In India, it has been described as a pest of castor,[19] pepper,[25] cotton,[26] tea,[11][27] mango, and peanut. Unlike other thrips, pupae of chilli thrips are generally found on leaves, leaf litter or on the axils of leaves, in curled leaves or under the calyces of flowers and fruits. Response of chilli thrips. Various formulations of imidacloprid used as either soil drench or foliar application provide effective control of Scirtothrips dorsalis without harming natural control agents. Bansiddhi, K., and S.

Seal DR, Klassen W, Kumar V. (2009a, in review). Scirtothrips dorsalis has not been reported feeding on mature host tissues. [22] Physically manipulating the host by removing preferred feeding sites has been shown to reduce thrips density on the plant, but also to increase the relative rate of between-plot dispersal.[21][23].

Scirtothrips dorsalis has been reported from South Africa and the Ivory Coast, and plant quarantine interceptions suggest that this pest is widely distributed across West Africa and is present in East Africa (Kenya).

[12] Nymphs entering the metamorphic process drop off of the plant during the first of two propual stages, and then complete their development in loose soil or leaf litter at the base of their host - but have been observed to pupate in any dark and humid crevice low on the plant, including bark and the folds of tightly packed lower leaves[14] or flowers. Adults of Orius insidiosus feed on all the life stages of thrips. Agriculture and Livestock of India 2: 391-403. Skarlinsky, T. 2004. Because Orius insidiosus also feeds on aphids, mites, moth eggs and pollen, its population does not decline strongly even if thrips populations are drastically reduced. There are numerous microtrichia and dark transverse antecostal ridges on the abdominal tergites as well as sternites.

According to Sanap and Nawale (1987), adult and nymphs of Scirtothrips dorsalis suck the cell sap of leaves, causing rolling of the leaf upward and leaf size reduction.

It is abundant on sacred lotus in Thailand (Mound and Palmer 1981), and on chilli peppers in India (Ramakrishna Ayyar 1932, Ramakrishna Ayyar and Subbiah 1935), where it is also a serious pest of peanuts (Amin 1979, 1980).

For example, a heavy infestation of Scirtothrips dorsalis in pepper plants changes the appearance of the plant to what is called "chilli leaf curl." 2018).

In the United States, USDA-APHIS inspectors at various ports-of-entry have intercepted Scirtothrips dorsalis 89 times since 1984 on imported plant materials belonging to 48 taxa (USDA 2004), and most frequently on cut flowers, fruits and vegetables.

Systemic neonicotinoids such as imidacloprid were once considered to be sparing of beneficial insects and natural predators, and recommended for integrated pest management of chilli thrips, especially when used as a soil soak or drip irrigation product[citation needed].

Recently, in Thailand its role as a vector of three tospoviruses (i.e., melon yellow spot virus (MYSV), watermelon silver mottle virus (WsMoV), and capsicum chlorosis virus (CaCV)) in field crops was confirmed (Chiemsombat et al. 2004. Imidacloprid suppresses Scirtothrips dorsalis populations for many days (Seal et al.
