and Rhoptromeris sp., Alysia sp., Trichoplasta sp., and Crataepiella sp. Reaction of Trichogramma chilonis to some pesticides commonly used in cotton fields. (2015).

Some of the important species that have been recorded from several insect eggs include Trichogramma minutum, Trichogramma evanescens, Trichogramma chilonis, Trichogramma pretiosum, and Trichogramma dendrolimi. on Mississippi central delta cotton, because T. pretiosum could develop at the 35°C temperatures common in that area. (1978) demonstrated differences between populations of the tachinid Lixophaga diatraeae. Trichogramma chilonis is an egg parasitoid. Especially in inundative release programs, the suitability of the released entomophage for its intended host must first be determined. Successful use of Trichogramma depends on its fit in the overall IPM program and should not be viewed as a replacement for insecticides (Smith, 1996).


Lumbierres et al. The combined use of O. majusculus, predatory midges, predatory thrips, and parasitoids clearly enhanced the suppression of aphids and thrips infesting sweet pepper, thus supporting the view that intraguild predation, which is potentially negative for biocontrol, could be compensated by positive effects of generalist predators for control of multiple pests (Messelink et al., 2011, 2013). successfully controlled F. occidentalis in France and Spain (Sampson et al., 2011). In Sweden, the predators Amblyseius (=Neoseiulus) cucumeris (Oudemans) and O. insidiosus were very effective when they were released together on four ornamental plants (Saintpaulia, Impatiens, Gerbera, and Brachyscome multifida) infested with F. occidentalis in greenhouses (Sorensson and Nedstam, 1993). ), were found effective against the citrus black fly, Aleurocanthus woglumi (Ashby) (Krishnamoorthy, 2010). (strain Bb-RSB). Likewise, Messing and Croft (1991) proposed that electrophoretic markers could be used to track the degree of field establishment and dispersal of imported foreign biotypes of phytoseiid mites. Tricogramma chilonis is supplied in 1 CC card and each card will have 16,000 to 20,000 parasitoides. Studies were conducted to investigate the compatibility of anthocorids with trichogrammatids (Gupta and Ballal, 2007). Among the various egg parasitoids that are known to exert considerable pressure on populations of insect pests, Trichogramma species are the most widely exploited and used for pest management across the world. (2010) evaluated the effect of plant quality on intraguild predation between Aphidoletes aphidimyza (Rondani) (Diptera: Cecidomyiidae) and O. laevigatus with A. gossypii as shared prey on greenhouse cucumber Cucumis sativus L. (with different N fertilization levels). Noctuid larvae that infest sugar beet and potato were controlled in the former USSR by releasing 20,000–60,000 parasitoids per ha, resulting in a 60–90% reduction in infestation levels (Beglyarov & Smetnik, 1977). Likewise, Haardt and Hoeller (1992) showed pronounced differences among six isofemale lines of the aphid parasitoid Aphelinus abdominalis (Dalman) with respect to life history traits. (2012) reported that ingestion of Bt protein by O. majusculus via plant leaves or pollen or via the food web has no negative effects on its biological parameters, while a positive effect with respect to increased fecundity and reduced developmental time was observed. The oriental mealybug, Planococcus lilacinus, was controlled by the local parasitoid, Tetranemoidea indica (Ayyar). The California red scale, Aonidiella aurantii (Mask. Another example of seeking a parasitoid species that is effective against its intended host was the selection of T. (Trichogrammanza) carverae (Oatman & Pinto), one of four candidate indigenous species of Trichogramma collected from vineyard egg masses of Epiphyas postvittana, as a potentially commercially viable biological control agent (Glenn & Hoffmann, 1997; Glenn et al., 1997).
sibericum were still higher than those of the commercial Trichogramma. Zhang F, 1998. Trichogramma chilonis Ishii is being used to control the diamondback moth, Plutella xylostella (Linnaeus), ... (20 cards) per ha from 10 days after germination for beans and 76,500 (30 cards) per ha starting 30 days after plant emergence for cassava.

Although several groups of egg parasitoids are commonly employed for biological control throughout the world, Trichogramma spp. Pupal parasitoids include Spalangia endius, Trichopria sp., Opius sp., Monelta sp. Trichogramma chilonis Ishii is being used to control the diamondback moth, Plutella xylostella (Linnaeus), on cole crops in Japan (Miura & Kobayashi, 1993) and in Germany (Wuehrer & Hassan, 1993).

Ruberson et al. have been used to control lepidopterous pests of peas and cabbage. (1989a) also compared the two biotypes and suggested using the intraspecific variability for genetic improvement. M. Kalyanasundaram, I. Merlin Kamala, in Ecofriendly Pest Management for Food Security, 2016. They then used the technique to determine the fate of an insecticide-resistant biotype of the parasitoid after field release (Edwards & Hoy, 1995b).

Charles V. Riley give the description for the first time in 1871 about trichogramma species. The most abundant parasitoids during the postrainy season in sorghum ecosystems are Aprostocetus sp., N. nyemitawus, Opius sp., and S. endius. Spraying of NSKE at 4.0% at the early growth stage of the crop and SlNPV at 250 LE per hectare is very effective. Ladurner et al. Jalali, ... B.L. Transgenic crops (cotton, maize, brinjal) are of prime importance as integral to IPM systems. This package will supply you with approx. Patil, in Insect Pests of Millets, 2017. Likewise, Li et al. The resulting parasitism amounts to 80% and the total cost is half that for insecticidal control (Huffaker, 1977). before mass production for inundative releases. (2014) reported that Spinosad had clear deleterious effect on Orius spp. The citrus green scale, Coccus viridis (Green), was effectively parasitized by Aneristus ceroplastae and Encyrtus lecaniorum (Mayr.) Harrison et al., (1985) likewise stressed the importance of precise taxonomic identification and biological testing of Trichogramma spp. Husseini et al. Eight species of parasitoids were found to be effective against the citrus leaf miner, Phyllocnistis citrella (Staint).
