NOTE ON THE CONTROL OF THE APPLE APHID BY NEW SYSTEMIC INSECTICIDES TRANSLOCATED FROM BARK TO FOLIAGE' Certain systemic insecticides, applied to the bark of the trunks of some trees, are translocated to the foliage (1). In a previous paper (2) it was shown that dimethoate fO,O-dimethyl S...
Neonicotinoids are active against a broad spectrum of economically important crop pests, including Aphidae (aphids), Aleyrodidae (whitefly), Cicadellidae (leafhoppers), Chrysomelidae (among others western corn rootworm), Elateridae (wireworms), Fulgoroidea (planthoppers), Pseudococcidae (mealybugs), ...
imidacloprid is applied as a systemic insecticide for the control of wood-boring insects in trees, residual imidacloprid in autumn-shed leaves poses risk of reduced leaf litter breakdown through a feeding inhibition effect on earthworms, and this has negative implications for organic matter dynamics ...
Flonicamid exhibits excellent performance for control of almost all important aphid species in apples, peaches, wheat, potato vegetables, cotton and ornamentals, etc. Flonicamid has no negative impact on pollinating insects or natural enemies, and thus, onicamid will provide a new option for integra...
Efficacy of Fungicide Treatments for Control of Anthracnose Canker in Young Cider Apple Trees in Western Washington Anthracnose canker, caused by Neofabraea malicorticis , threatens the sustainability of cider apple ( Malus 脳domestica ) production in the maritime climat...

). Four aphid control strategies, namely intensive, optimised, input-substitution, and integrated control, were compared in France (Penvern et al. 2010). The use of pesticides lowered densities of aphids as well as those of their natural enemies while cultural methods (e.g., ground cover and...
Residue levels significantly depended on the dose and compound applied, as well as the physiological parameters of the trees. Englert et al. (2017b) reviewed the literature on foliar residues of neonicotinoids and found that they ranged between 1000 and 6000 ppb for soil and trunk application in...
(fiveCLas-infectedD. citriper plant and a seven-day inoculation access period) to untreated control plants was 93%. In contrast,CLas transmission was reduced to 38.8% when test plants were protected by systemic insecticides. Our results indicated that all insecticides tested presented a potential ...
Preliminary attempts in our laboratory using injection have led to significant mortality in control individuals, probably due to the small size of A. glycines (about 10 times smaller than the pea aphid). Feeding dsRNA through artificial diet or plants offers the best option for RNAi in this ...
