“…Given the disruptive effects of insecticides, it is important to choose materials that have as least disruptive effects on natural enemies, such as parasitic wasps. For example, the use of selective insecticides, such as Bacillus thuringiensis , for the management of lepidopteran pests is recommended, as such selective insecticides allow survival of leafminer parasitoids …”

Liriomyza trifolii (Burgess) is a highly invasive species that has become established in agricultural and ornamental crops throughout the world. L. trifolii was first recorded in China in 2005 in Guangdong Province. Subsequently, its known distribution in China has rapidly expanded to another 11 provinces (Zhejiang, Jiangsu, Shanghai, Fujian, Guangxi, Shandong, Hainan, Hebei, Henan, Hubei and Anhui), where it is currently causing considerable damage and economic losses. Experimental research and field surveys have contributed to our understanding of the ecology of L. trifolii and particularly the process of invasion and its interactions with other established, exotic Liriomyza leafminer species. A number of factors have contributed to the successful establishment of L. trifolii and displacement of interspecific competitors. In China, L. trifolii has become a particularly devastating pest in areas with intensive farming with extensive monocultures and a reliance on insecticide use. Integrated pest management incorporating judicious applications of insecticide combined with biological and cultural controls is likely to provide the best long-term management strategy for L. trifolii. We provide information regarding 10 years of L. trifolii invasion in China and discuss areas of future research to enhance our overall understanding of the biology and ecology of L. trifolii and to improve management programmes for this widespread invasive insect pest. © 2017 Society of Chemical Industry.

“…In addition it had been only a minor, sporadic pest in California prior to 1992 (Lange et al, 1957). Liriomyza huidobrensis also appears to be extending its predominance southward in California (Reitz et al, 1999). At the same time the distribution of L. trifolii has become limited in the central coast region.…”

In recent years, the pest status of Liriomyza trifolii (Burgess) and L. huidobrensis (Blanchard) (Diptera: Agromyzidae) has changed in California, as well as other areas of the world. In California, L. huidobrensis has become the predominant Liriomyza species in valleys along the central coast, while L. trifolii remains the predominant species in southern California. To investigate possible reasons for this change in status, differences in host plant use and reproductive success of intraspecific populations were examined for Liriomyza trifolii and L. huidobrensis from both central and southern California. The southern L. trifolii fed, oviposited and reproduced successfully on all five hosts tested, but the central population fed significantly less on all hosts and was restricted to reproducing on pepper only. With the exception of pepper, southern L. trifolii had significantly greater larval survival on all hosts than central L. trifolii. In contrast, the central L. huidobrensis population had greater reproductive success than the southern population of that species on all hosts plants tested. However, pepper was not a suitable host for either L. huidobrensis population. Both species showed positive assortative mating, with homotypic mating occurring more frequently than heterotypic mating; however, the difference between L. trifolii populations was much more pronounced than between L. huidobrensis populations. These data indicate that central and southern California populations of each species are distinct biotypes. Furthermore when coupled with previous genetic data, our results suggest the possible existence of cryptic species within L. trifolii.

“…In cabbage production in Indonesia, IPM increased the marketable cabbage yield by 57% at Lembag and 19% at Pangalengan when compared with the conventional pest management practice (Sastrosiswojo et al., ). In on‐station trials, Reitz, Kund, Carson, Phillips, and Trumble () evaluated a low‐pesticide‐input management system for celery ( Apium graveolens L.). IPM used significantly fewer insecticide applications, but no significant differences in total number of marketable produce were found; however, IPM's lower input (insecticide) costs resulted in a greater net profit.…”

Integrated pest management (IPM) versus farmers’ pest management practices were evaluated in potato (Solanum tuberosum L.) in the central coast of Peru. IPM technologies consisted of seed treatment, insect pest, and disease scouting using action thresholds for decision making to apply pesticides, and the use of trapping devices and selective insecticides versus chemical control by potato farmers. An ecological, environmental, and economic analysis of both approaches was carried out by using biodiversity indices, environmental impact indicators, and partial budget analysis. The leafminer fly Liriomyza huidobrensis (Blanchard) and the bud midge Prodiplosis longifila (Gagne) were the most important pests during the cropping season. Larval infestation of both pests and leafminer foliar damage were less in IPM plots. Almost twice as many pesticide (insecticide and fungicide) applications per season were carried out on farmers’ practices plots with 16.7 sprayings compared to 9.7 sprayings in IPM plots. The total quantity of pesticides used per season was higher under farmers’ practices (4,614.3 g a.i./ha) than in IPM (2,042.6 g a.i./ha) plots. Likewise, farmers applied five times more insecticides (3,620.3 g a.i./ha) than IPM (722.55 g a.i./ha). Methamidophos and chlorpyrifos accounted for 65% of the environmental impact (EI) value of 137/ha in farmers’ fields. IPM strategies reduced the EI to 42.4/ha, which represents a reduction of 69.2%. Further, IPM achieved 35% higher marketable potato yield than farmers’ practices. Partial budget analysis showed a higher net profit in all IPM plots, with an average increase of US$1,410/ha. The field trials demonstrated the environmental and economic viability of IPM for potato in the central coast of Peru. However, while there are effective integrated components for leafminer fly management, there is a clear need to develop and integrate more sustainable and ecological pest management strategies for other economically important pests such as the bud midge.
