The Chilean plants Discaria chacaye, Talguenea quinquenervia (Rhamnaceae), Peumus boldus (Monimiaceae), and Cryptocarya alba (Lauraceae) were evaluated against Codling moth: Cydia pomonella L. (Lepidoptera: Tortricidae) and fruit fly Drosophila melanogaster (Diptera: Drosophilidae), which is one of the most widespread and destructive primary pests of Prunus (plums, cherries, peaches, nectarines, apricots, almonds), pear, walnuts, and chestnuts, among other. Four benzylisoquinoline alkaloids (coclaurine, laurolitsine, boldine, and pukateine) were isolated from the above mentioned plant species and evaluated regarding their insecticidal activity against the codling moth and fruit fly. The results showed that these alkaloids possess acute and chronic insecticidal effects. The most relevant effect was observed at 10 µg/mL against D. melanogaster and at 50 µg/mL against C. pomonella, being the alteration of the feeding, deformations, failure in the displacement of the larvae in the feeding medium of D. melanogaster, and mortality visible effects. In addition, the docking results show that these type of alkaloids present a good interaction with octopamine and ecdysone receptor showing a possible action mechanism.

Radiographic techniques were investigated for their potential to detect internal pests in deciduous tree fruits. Two non-destructive methods, X-ray CT imaging and film X-ray, were used to detect larval feeding damage caused by codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), in apples. In addition, CT imaging was used to detect larvae of the codling moth and western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), in cherries. Both techniques showed evidence of codling moth feeding tunnels in apples, as well as in cherries using CT imaging. CT images of cherries infested with fruit fly larvae showed retraction of the fruit pulp from the seed. This study supports the use of radiography to detect internally damaged fruits for sorting on the commercial packing line.

The essential oil from the seeds of oriental medicinal plant Poncirus trifoliata (L.) Raf. was tested for repellent and fumigant efficacy on fruit fly (Drosophila melanogaster) and mosquito (Anopheles culicifacies). The oil showed potent activity with 76.2 and 93.2% mortality in fumigant assay, and 77.1 and 93.2% repellent efficacy on fruit fly at doses of 100 and 200 μg/ml, respectively. The application of oil against mosquito showed 80.0% mortality in fumigant assay and 70.3% repellency at 100 μg/ml dose. Thus, essential oil of P. trifoliata seeds can be considered as a potential source of biologically active compounds for pest control.

Nine hydroxytriazenes have been synthesized and screened for their insecticidal activity against one day oldDrosophila melanogasterMeig (Fruit fly). Out of all the nine compounds screened, 3-hydroxy-3-n-propyl-1-m-chlorophenyltriazene is the most active having LC50values 0.9847 ppm. The least active compound is 3-hydroxy -3-n-propyl-1-p-methylphenyltriazene, whose values are 16.52 ppm. In general, the LC50values range from 3.92 to 5.52 ppm.

Abstract Detection of pest infestations in fresh produce traded internationally could offer improved prospects for reducing the movement of unwanted pests. Because immature stages of some pests can be difficult to find visually, other cues such as herbivore-induced volatiles that can potentially be detected at the early stages of infestation are worth investigating. In this study, we artificially infested postharvested apples (Malus × domestica ‘Royal Gala’) with two economic apple pests, the specialist codling moth (CM, Cydia pomonella Linnaeus, Lepidoptera: Tortricidae) and the generalist Queensland fruit fly (QFF, Bactrocera tryoni, Froggatt, Diptera: Tephritidae) and collected volatile organic compounds (VOCs) over time (days 0, 6, and 14–15). In both infestation experiments, we found a strong and significant interaction between time and treatment. Apples infested with the QFF emitted lower total amounts of VOCs than uninfested apples, whereas apples infested with the CM released similar total amounts of VOCs. Apples infested with CM had increases in several hexyl and butyl esters, which were particularly noticeable after 15 d. In contrast, changes in ethyl esters were characteristics of QFF infestation and could be detected from day 6. Our multilevel and multivariate statistical analysis identified specific volatile biomarkers for each species at each sampling time that can be used to design a new tool for remote detection and surveillance of these invasive pests in harvested apples. Nevertheless, other information such as the cultivar as well as the storage condition needs to be taken into consideration to increase accuracy of future odorant-based sensors for pest identification.

We attempted to search novelBacillus thuringiensisstrains that produce crystals with potential utility in plant protection and with higher activity than strains already used in biopesticide production. SevenB. thuringiensissoil and water isolates were used in the research. We predicted the toxicity of their crystals bycrygene identification employing PCR method. The isolate MPU B63 with interesting, according to us, genes content was used in evaluating its crystal toxicity againstCydia pomonellacaterpillars. The strain MPU B63 was cultured from water sample and hadcry1Ab,cry1B, andcry15genes. The LC50crystals of MPU B63 were compared to LC50of commercial bioinsecticide Foray determined againstC. pomonella(codling moth). The activity of MPU B63 inclusions against codling moth larvae was approximately 24-fold higher than that of Foray. The results are a promising introduction for further study evaluating the potential usefulness of isolate MPU B63 crystals in plant protection.
