“…Other comparative studies have generally shown that L. trifolii is less susceptible to insecticides than is L. sativae [14]–[16]. An exception to these general trends is a study conducted with Japanese populations of these species that found either no significant difference in susceptibilities, or lower susceptibilities of L. sativae , to 25 different insecticides [17].…”

Liriomyza sativae and L. trifolii are highly invasive leafminer pests of vegetable crops that have invaded southern China in recent years. Liriomyza sativae was the first of these species to invade China, but it is now being displaced by L. trifolii. The rate and extent of this displacement vary across southern China. In Hainan, monocultures of highly valuable cowpea are planted and treated extensively with insecticides in attempts to control leafminer damage. In Guangdong, cowpea fields are interspersed with other less valuable crops, such as towel gourd (Luffa cylindrica), which receive significantly fewer insecticide applications than cowpea. To determine how differences in cropping systems influence the Liriomyza species composition, we conducted field trials in 2011 and 2012 in Guangdong where both species were present. We replicated conditions in Hainan by planting cowpea monocultures that were isolated from other agricultural fields, and we replicated conditions in Guangdong by planting cowpea in a mixed crop environment with towel gourd planted in neighboring plots. We then compared leafminer populations in cowpea treated with the insecticide avermectin and untreated cowpea. We also monitored leafminer populations in the untreated towel gourd. Untreated cowpea and towel gourd had comparatively low proportions of L. trifolii, which remained relatively stable over the course of each season. Avermectin applications led to increases in the proportions of L. trifolii, and after three weekly applications populations were >95% L. trifolii in both crop systems. However, the rate of change and persistence of L. trifolii in the mixed crop system were less than in the monocrop. These results indicate that L. trifolii is much less susceptible to avermectin than is L. sativae. Further, L. sativae was able to persist in the untreated towel gourd, which probably enabled it to recolonize treated cowpea.

“…For example, whiteflies may be controlled using parasitoids and the insecticides buprofezin, lufenuron or pymetrozine, which are harmless to the parasitoids. Other serious insect pests-leaf miners, the corn earworm and thrips-are controlled by cyromazine Ohta et al 2005;Tokumaru et al 2005), Bts (Someya and Shimizu 1997;Souda 1998;Nishimori et al 2000) and flufenoxuron Ohta et al 2005;Tokumaru et al 2005;Someya and Shimizu 1997;Souda 1998;Nishimori et al 2000;Tsuruta et al 1999), respectively, which are also harmless to the parasitoids.…”

Effect of insecticides on the mortalities of three whitefly parasitoid species, Eretmocerus mundus, Eretmocerus eremicus and Encarsia formosa (Hymenoptera: Aphelinidae)

The toxicities of 24 insecticides for the biological control of whiteflies were evaluated for Eretmocerus mundus (Mercet), Eretmocerus eremicus Rose and Zolnerowich and Encarsia formosa Gahan using the residual film method (for adults) and the dipping method (for pupae). Mortalities from insect growth regulators (IGRs) (flufenoxuron and lufenuron), Bacillus thuringiensis (Bt), pymetrozine and sulfur were\30% for both pupae and adults of all three species, indicating that the parasitoids were not seriously affected by these insecticides. Neonicotinoids (acetamiprid, clothianidin, dinotefuran, imidacloprid and nitenpyram), synthetic pyrethroids (etofenprox and permethrin), organophosphates (acephate and fenitrothion), chlorphenapyr, emamectin benzoate, spinosad and tolfenpyrad were seriously harmful (100% mortality) and acaricides (chinomethionat, milbemectin and pyridaben) were moderately harmful or seriously harmful to adult parasitoids (leading to mortalities of [92%). For each insecticide, the mortality of pupae was generally lower than that of adults, even though the toxicity classification for the two groups was similar. The results indicate that IGRs, Bt, pymetrozine and sulfur are relatively harmless, and are compatible with the use of parasitoids to help control whiteflies for integrated pest management in greenhouses.

“…In the present study, we have reported the geographical distribution and host range of four leafminer fly species in eastern Brazil. The correct identification of the species and strains is a crucial step for the management of leafminer fly pests because they exhibit differences in insecticide susceptibility, fecundity, host range, symbiont infection and natural enemies (Macdonald, ; Reitz & Trumble, ; Tokumaru et al ., ; Gao et al ., ). The simultaneous occurrence of four different species in the same region with overlapping hosts reinforces the need for proper species identification.…”

Host range and genetic strains of leafminer flies (Diptera: Agromyzidae) in eastern Brazil reveal a new divergent clade ofLiriomyza sativae

1 Leafminer flies are phytophagous and cosmopolitan pests. Leafminer fly outbreaks and damage to cultivated plants have steadily increased in several regions in the world. 2 In the present study, we report host range, geographical distribution, Wolbachia infection and mitochondrial strains of leafminer fly species from eastern Brazil. 3 Four leaf miner fly species were identified using cytochrome c oxidase subunit I DNA barcoding. Liriomyza sativae is the main pest as a result of its high polyphagy and wide distribution. Liriomyza brassicae, Liriomyza huidobrensis and Calycomyza malvae are important in Brassicaceae, Curcubitaceae and Malvaceae crops, respectively. 4 There is no relationship among host range, geographical distribution and mitochondrial strains of leafminer fly species. We did not find Wolbachia infection in any of the specimens collected. 5 Phylogeographical analyses suggests that there are four strains of L. sativae in the world, one of which is endemic from Brazil. The lack of shared haplotypes between Brazilian specimens and those from other world regions indicates the absence of recent gene flow of leafminer flies from Brazil with specimens from Americas and Old world. The exception is L. brassicae, which exhibits one haplotype shared among Brazil, Philippines and Sri Lanka. 6 The host range identification and geographical isolation of leafminer fly species from Brazil comprise useful information for quarantine and pest management purposes.
