“…However, botanical pesticides and the use of some cultural practices have potential to control these midges and are more environmentally friendly. Botanical pesticides may reduce the development of pest resistance, the need of pesticide applications, and the cost of pest management (Regnault-Roger 1997, Khorram et al 2011). Neem products have value in pest management due to their selectivity toward phytophagous insects and minimal toxicity to many beneficial insects (Naumann andIsman 1996, Bhanukiran andPanwar 2000).…”

Since 2005, mango has been damaged by a group of new pests, the gall midges, in all mango-growing areas of Pakistan. Little is known about these pests in Pakistan. In this report, we present information on the occurrence, damage patterns, methods for monitoring, and management of Procontarinia mangiferae (Felt), a mango gall midge found in the country. At the study site (Rahim Yar Khan, a district of the province Punjab, Pakistan), the pest was active from January/February to April as eggs, larvae, and adults on mango inflorescence buds, branches (axillaries), and immature fruits. Females of P. mangiferae oviposited in inflorescence tissues, and larvae, after feeding on plant tissues, dropped to the soil under the mango trees for pupation from February to April. Mango trees in commercial orchards were more heavily damaged by P. mangiferae than were isolated trees in farmer fields (66.7%). The adults of P. mangiferae were captured on sticky traps of all tested colors, and were in flight from January to May. Captures per trap were highest on yellow traps, followed by green, blue, and clear traps. Control of mango gall midge was effectively provided by the synthetic insecticide bifenthrin (Talstar 10 EC) and also by application of neem seed kernel extract on the tree canopy if integrated with raking the soil under the mango tree canopy.

“…In fact, high mortality was observed when L. decemlineata 2nd instar larvae were exposed to potato leaf disks treated with concentrations of 5–20 ppm of cis ‐hex‐3‐enyl acetate. Some selected monoterpenes, mainly limonene, myrcene, and terpinene, have toxic effects to the 2nd instar larvae of L. decemlineata , with a percent mortality that varied from 15% to 100% (Khorran, Nasabi, Jafarnia, & Khosroshahi, ). In addition, the results of Saroukolai, Nouri‐ganbalani, rafiee‐dastjerdi, and Hadian () revealed that the essential oil of Satureja khuzistanica has strong toxicity and antifeedant activity against the 4th instar larvae of CPB, showing that the effective dose had even stopped food consumption without killing the insect.…”

Black nightshade (Solanum nigrum, S. nigrum L.) and red nightshade (Solanum villosum, S. villosum Mill.) are medicinal plants from the Solanaceae family that synthesize glycoalkaloids and other secondary metabolites. To recognize the potential insecticide activity of these compounds, leaf extracts (containing glycoalkaloid and methanol fractions) were tested for enzyme inhibition, antifeedant activity and toxicity. For in-vitro glutathione S-transferase (GST) inhibition activity, we used insecticide-resistant Colorado potato beetle, Leptinotarsa decemlineata (L. decemlineata; Say) midgut and fat-body homogenate. In-vivo toxicity and the antifeedant activity were performed using larval bioassays. The methanol extracts had greater GST inhibitory activity compared to the glycoalkaloids, as well as greater 2nd instar larvae mortality and antifeedant activity.Furthermore, the green leaf volatile compound, cis-hex-3-enyl acetate, at the concentration of 5 ppm, caused 50% mortality of 2nd instar larvae. Our findings suggest the Arch. Insect Biochem. Physiol. 2019;101:e21550.wileyonlinelibrary.com/journal/arch

“…This component has a broad insecticidal activity and acts against agricultural and stored-product insects (Ahn et al 1998;Isman 2000). Kordali et al (2007) reported that 1,8-cineole, fenchone, β-pinene, and γ-terpinene can be used as potential control agents against both the larvae and adults of CPB; Safaei Khoram et al (2011) reported that limonene and myrcene have a strong toxicity to the 2 nd instar larvae and adults and α-pinene has a relatively high toxicity to adults. In this study we found that carvacrol can exert a high effect on nutritional indices of this pest.…”

Taghizadeh Saroukolai A., Nouri-Ganbalani G., Rafiee-Dastjerdi H., Hadian J. (2014): Antifeedant activity and toxicity of some plant essential oils to Colorado potato beetle, Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae). Plant Protect. Sci., 50: 207-216.Essential oils of Satureja khuzistanica Jamzad, Ocimum basilicum L., Myrtus communis L., Thymus daenensis Celak, Mentha spicata L., and Eugenia caryophyllus (Sprengel) were evaluated for nutritional indices and mortality of the 4 th instar larvae and adults of Leptinotarsa decemlineata (Say). Relative growth rate, relative consumption rate, efficiency of conversion of ingested food and feeding deterrent index were measured. Results showed that the most efficient essential oil on the 4 th instar larvae and adults was S. khuzistanica (LC 50 = 23.36 and 167.96 ppm, respectively). Even if all essential oils were effective on feeding deterrence of both stages of L. decemlineata, the essential oil of S. khuzistanica was the most effective. So, these essential oils can be used as potential control agents against both stages of L. decemlineata.
