Minutes for fiscal Year 2015

The following are brief synopses of the minutes of the meetings of the Hawaiian Entomological Society for the fiscal year 2015. The HES fiscal year runs from March 1 to the end of February of the following year. More detailed minutes are kept with the Secretary of the Society

First Records of Parasitoids Attacking the Asian Citrus Psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), in Hawaii

amarixia sp. prob. radiata (Hymenoptera: Eulophidae) and Diaphoren- cyrtus aligharensis (Hymenoptera: Encyrtidae), two natural enemies released against the Asian citrus psyllid (Diaphorina citri) in various areas around the world, were discovered attacking this pest on the island of Oahu, Hawaii, in 2012

Astrophysical Condition on the attolensing as a possible probe for a modified gravity theory

We investigate the wave effect in the gravitational lensing by a black hole with very tiny mass less than 10^-19 solar mass, which is called attolensing, motivated by a recent report that the lensing signature might be a possible probe of a modified gravity theory in the braneworld scenario. We focus on the finite source size effect and the effect of the relative motion of the source to the lens, which are influential to the wave effect in the attolensing. Astrophysical condition that the lensed interference signature can be a probe of the modified gravity theory is demonstrated. The interference signature in the microlensing system is also discussed.Comment: Accepted for publication in IJMP

Classical Cepheids, what else?

We present new and independent estimates of the distances to the Magellanic Clouds (MCs) using near-infrared (NIR) and optical--NIR period--Wesenheit (PW) relations. The slopes of the PW relations are, within the dispersion, linear over the entire period range and independent of metal content. The absolute zero points were fixed using Galactic Cepheids with distances based on the infrared surface-brightness method. The true distance modulus we found for the Large Magellanic Cloud---$(m-M)_0 = 18.48 \pm 0.01 \pm 0.10$ mag---and the Small Magellanic Cloud---$(m-M)_0 = 18.94 \pm 0.01 \pm 0.10$ mag---agree quite well with similar distance determinations based on robust distance indicators. We also briefly discuss the evolutionary and pulsation properties of MC Cepheids
