Background: Alysiinae Leach is a species-rich subfamily in Braconidae, of which several species play an important role in biological control. The monotypic genus Bhat, 1980 was discovered in Tibet and Yunnan provinces for the first time, representing the first record of the genus Bhat, 1980 (Braconidae, Alysiinae) in China.

New Information: The rare genus Bhat, 1980 (Braconidae, Alysiinae) and its only known species, Bhat, 1980, are newly recorded from China.

Article Synopsis
  • Drosophila suzukii, or Spotted Wing Drosophila (SWD), poses a significant economic threat to berry and stone fruit production globally, as it can reproduce in wild fruits that surround cultivated fields.
  • Integrated Pest Management strategies suggest that biological control, particularly using parasitoids, could help manage SWD populations more effectively by targeting non-cultivated habitats.
  • Recent surveys conducted in South Korea and China identified several new parasitoid species from the genus Asobara that could potentially be used for classical biological control against SWD in areas where it has become invasive.

Two new species of the genus Leptotrema van Achterberg, 1988 and one new genus of the Alysiinae from Mt Wilhelm, Madang Province, Papua New Guinea are described and illustrated. The distribution of the genus Leptotrema is extended to the Australasian region. Three new combinations are established Idiasta fulmeki (Fischer, 2010) comb.

The family Trigonalyidae is considered to be one of the most basal lineages in the suborder Apocrita of Hymenoptera. Here, we determine the first complete mitochondrial genome of the Trigonalyidae, from the species Taeniogonalos taihorina (Bischoff, 1914). This mitochondrial genome is 15,927bp long, with a high A+T-content of 84.

Syconia of figs (Moraceae: Ficus spp.) harbour many wasp species, mostly belonging to several genera of chalcidoids (Hymenoptera: Chalcidoidea). In contrast, only two genera of Braconidae (Hymenoptera: Ichneumonoidea) with a few known species are found in syconia belonging to the subgenus Urostigma.

Premise Of The Study: Although many species in the orchid genus Coelogyne are horticulturally popular, hardly anything is known about their pollination. Pollinators of three species were observed in the field in Nepal. This information is urgently needed because many orchid species in Nepal are endangered.

Olfactometer tests with Asobara tabida (Nees 1834), a larval endo-parasitoid of frugivorous Drosophilidae showed that females are attracted to the odour of host food: a suspension of living yeast. This attraction decreased as the fermenting medium grew older and became less likely to contain suitable host stages. Olfactometer tests with - what was considered to be - A.
