The short-term behavioral responses of adult grasshoppers, Melanoplus sanguinipes (F.) (Orthoptera: Acrididae), were examined after they experienced changes in microclimate when beingforced to change positions in their habitat. It was also determined if and when behavioral tactics allowed adults to achieve body temperatures within their preferred range. The preferred or set-point range, here ta...

Abstract. Kumar P, Thakur TS, Deepika, Sharma N. 2022. Diversity studies on insect pests of high altitudinal transitional zones North-western Himalayas. Nusantara Bioscience 14: 203-210. Class Insecta constitute a major fauna and comprise many species economic importance. Due to climate change increase in temperature, are changing their habitat considerably shifting hosts, which leads changes t...

The first findings of egg-parasitoids of the invasive planthopper Ricania speculum (Walker) (Hemiptera Ricaniidae) are presented. Aprostocetus (Ootetrastichus) crino (Walker) (Hymenoptera Eulophidae), a native species until now only associated with Oecanthus spp. (Orthoptera Oecanthidae) eggs, was the most common. Chaetostricha similis (Silvestri) (Hymenoptera Trichogrammatidae) and Polynema sp...

In order to describe grasshopper (Orthoptera: Acrididae) species composition, diversity, abundance, and density of four rangelands types, we compared the grasshopper community composition and dynamics in the rangeland of the northern slopes of the Qilian Mountains. In total, 55 grasshopper species were collected from 2007 to 2009, representing three families and six subfamilies. The subfamily O...

While the mRNA expression patterns of homeotic genes have been examined in numerous arthropod species, data on their protein accumulation is extremely limited. To address this gap, we analyzed the protein expression pattern of the hox gene Sex combs reduced (Scr) in six hemimetabolous insects from four divergent orders (Thysanura, Orthoptera, Dictyoptera and Hemiptera). Our comparative analysis...

Grasshopper species belonging to subfamilies Melanoplinae, Gomphocerinae and Oedipodinae were tested for their feeding rate on three types of grass. All grasshopper species were offered Shawnee and Kanlow cultivars of switchgrass, Panicum virgatum L. and big bluestem, Andropogon gerardii Vitman. The grasshoppers, Melanoplus femurrubrum and Melanoplus differentialis were also tested for their fe...

The body axes of many animals are initially patterned by the asymmetric distribution of maternal mRNAs and proteins in the oocyte. In Drosophila, these maternal factors are synthesized by the 15 nurse cells that connect to each oocyte within the ovary. However, insect ovaries fall into three anatomical categories, of which Drosophila represents only one. The telotrophic meroistic ovaries of the...
