“…4) and resulted in savings of more than $US 20 million per year to growers, (30) as well as providing ''proof of principle'' that laboratory selection could yield improved natural enemies for use in pest management programs. The savings ($24-44 per acre) were due to the reduced use of pesticides to control spider mites, which was …”

Metaseiulus occidentalis is a representative of an important family of mites (Arthropoda: Chelicerata: Acari: Phytoseiidae) that are effective predators of pest mites in agricultural crops around the world. Like many arthropods, this mite contains multiple genomes, including the genomes of several microbial symbionts as well as its own mitochondrial and nuclear genomes. The mitochondrial genome is "mitey" large at 25 kb, due to duplication and triplication of genes. By contrast, the nuclear genome is "mitey" small at 88 Mb. This mite has a parahaploid genetic system, tolerates inbreeding, and has a haploid chromosome number of 3. This predator was genetically improved for use in agriculture by developing strains that lacked the ability to overwinter in diapause or were resistant to multiple pesticides, and can be genetically modified using recombinant DNA methods. Sequencing the nuclear genome would provide useful insights that could enhance genetic improvement programs that would result in improved pest management, could provide genes needed to resolve the evolutionary relationships of this family, and could serve as a model for understanding the evolution and genetics of chelicerate arthropod predators.

ÖzetBu derleme makalede bazı insektisit gruplarının Chrysopidae familyası türlerinin yumurta, larva ve erginleri üzerindeki etkisi kalitatif olarak araştırılmıştır. Literatür bilgilerine göre fenoksikarbın ovisidal etkisinin bulunduğu saptanmıştır. Diafenthiuron ve Buprofezin insektisitleri larvalarda yüksek konsantrasyonlarda toksik etki göstermiştir. Acetamiprid ve Thiamerthoxam'ın düşük konsantrasyonlarda dahi toksik etkisinin bulunduğu gözlenmiştir. Azadirachtin yumurta bırakmada negatif etkili bir insektisit olurken, Lufenuron yeni doğan larvalarında mortaliteyi indükleyici etki yapmıştır. Spinosad ve Cypermethrin ise yumurta gelişim zamanını olumsuz yönde etkilemiştir.Anahtar Kelimeler: Chrysopidae, Selektif insektisit etkisi, Karbamat, Acetamiprid, Organofosforlu insektisitler, Biyokontrol Ajanı Effect of Several Insecticides Groups on some Species Belonging to the Chrysopidae Family Schneider 1851 AbstractIn this review article, some of insecticide group's impact on the of eggs, larvae and adults of Chrysopidae family has been investigated qualitatively. According to the light of literature informations, Fenoxycarb has been founded an ovicidal effect. High concentrations of Buprofezin Diafenthiuron observed to be toxic to larvae. It was found that Acetamiprid and Thiamerthoxam have toxic effectly insecticides even low concentrations. Azadirachtin insecticide has a negative effective on the cessationing eggs, Lufenuron has effected as mortalityinducing on the newborn larvae. Spinosad and cypermethrin adversely affected to the development time of the egg.

“…The most successful and widely used are the pesticide resistant strains of Metaseiulus occidentalis (Nesbitt), Amblyseius fallacis (Garman) and Typhlodromus pyri Scheuten. Headley and Hoy (1987) estimated that the use of the carbaryl-organophosphate-sulfur resistant strain of M. occidentalis as the keystone of integrated mite management has resulted in an annual savings of over 20 million dollars to the California almond industry alone. Resistant M. occidentalis strains are also used in other crops and geographical areas (Hoy, 1992).…”

Kostiainen, T. and Hoy, M.A., 1994. Genetic improvement of Amblyseius finlandieus (Acari: Phytoseiidae): laboratory selection for resistance to azinphosmethyl and dimethoate. Exp. Appl. Acarol., Amblysei~finlandicus (Oudemans) was selected in the laboratory for resistance to azinphosmethyl and dimethoate by subjecting adult females to increasing concentrations of dried residues of dimethoate and azinphosmethyl on detached bean leaves. The first eight selections were done with dimethoate. Slide-dip bioassays indicated selection with dimethoate increased dimethoate resistance 1.8-fold and azinphosmethyl resistance 2.6-fold. These resistances appeared to be quite stable: a 1.2 to 1.3-fold decrease in resistance ratios was observed in a subculture after 10 months without selections. No decrease was observed after 9 months without selections in a pooled colony that consisted of both resistant and susceptible miles. The dimethoate-selected colony was subsequently selected eight times with azinphosmethyl. About 15 % of the mites survived the last selection round with 2,500 ppm, which is 2.5 times the highest recommended field rate in Finnish apple orchards. At the end of the selection program, based on slide-dip bioassays, the total increase in resistance to dimethoate was about two-lbld and to az.inphosmethyl about 5.4-fold compared to the unselected base colony from which the selected colony was derived. The LCs0 value for azinphosmethyl was 14 times higher in the selected colony (451.3 ppm a.i.) compared to the most susceptible colony tested. A similar level of resistance to both pesticides was achieved after six azinphosmethyl selections on a mixed colony that was initiated by pooling mites from five field-collected colonies and the dimethoateselected lines. Year-to-year variation in azinphosmethyl LC~0 values of the unselected base colony was high, with values varying from 83.8 to 348.7 ppm a.i., demoustrating the need to test a reference strain in each bioassay. Resuhs of the azinphosmethyl selections and the subsequent slide-dip bioassays suggest that the resistant strain could tolerate field rates of azinphosmethyl (300-950 ppm a.i.) used in Finnish apple orchards.
