Liriomyza trifolii is an important pest of vegetables and ornamental crops around the world. This pest is attacked by many parasitoid species. The principal management tactic used against L. trifolii is insecticide application. Insecticides vary in their effects on parasitoid species and insecticides that have less harmful effects should be preferred for the control of this pest. In this study, novaluron, abamectin, λ-cyhalothrin and spinetoram were investigated for their lethal effects on adults of Neochrysocharisformosa and Ganaspidium nigrimanus, two important parasitoids ofL. trifolii. Three different bioassays were used on adult parasitoids： direct insecticide application, insecticide intake and insecticide residue. Adult parasitoid response to novaluron exhibited the least lethal effects among the bioassays and insecticides tested. Abamectin had significant mortality to both parasitoid species in the direct application and insecticide intake bioassays and mortality were high for G. nigrimanus in the residue bioassay. Spinetoram was the most harmful insecticide to the adult parasitoids in all three bioassays. λ-cyhalothrin effects varied between the two parasitoids. In the direct application, it was harmful to G. nigrimanus and had no effect on N. formosa. In the insecticide intake bioassay λ-cyhalothrin had no effect in survival of either species, and in the residue bioassay it reduced parasitoid survival of both species. Potential tolerance of N. formosa to λ-cyhalothrin is discussed.

Dear Editor,Metabolically induced cancer heterogeneity creates a large source of novel potential targets towards an enhanced therapeutic window alone and in combination with classic chemo-and radiotherapy[1,2].This is of particular interest for non-small cell lung cancer(NSCLC),which accounts for more than 80%of all lung tumor types characterized by limited responses to current treatment options[3–5].

Bipolar molecules incorporating donor and acceptor components within a single molecule provide new device opportunities due to their intrinsic behavior as nanoscale p-n heterojunctions. The suitability of such molecules for photovoltaic applications depends on many factors, including the energy and spatial distribution of molecular orbitals, the influence of environment, how the molecules are assembled, and optical excitation response. Here we report a direct characterization of the local electronic structure of the bipolar molecule bithiophene naphthalene diimide （BND）. Using scanning tunneling spectroscopy, we were able to study the internal electronic structure of individual BND molecules on a thin insulating layer of NaCl. We find that BND molecules exhibit type II heterojunction behavior with orbital energy shifts occurring over subnanometer intramolecular interface distances. At higher coverage on metal substrates BND molecules with different bridge structures self-assemble into 1-d molecular chains. Our experimental results can be understood through the use of first-principle theoretical modeling, and provide new insights into how these molecular systems might be optimized.
