Insect odorant binding proteins (OBPs) are thought to involve in insects' olfaction perception. In the present study, we identified 38 OBP genes from the antennal transcriptomes of Spodoptera litura. Tissue expression profiles analysis revealed that 17 of the 38 SlitOBP transcripts were uniquely or primarily expressed in the antennae of both sexes, suggesting their putative role in chemorecepti...

20-Hydroxyecdyone (20E), an active form of ecdysteroid, is the key hormone in insect growth and development. To date five P450 enzymes involved in the last four steps of ecdysteroid biosynthesis from ketodiol to 20E namely Spook (Spo), Phantom (Phm), Disembodied (Dib), Shadow (Sad) and Shade (Shd) related to ecdysteroid biosynthesis, are identified and the character of last four enzymes is well...

Spodoptera litura (S. litura) is one of the most destructive agricultural pests worldwide. There is urgent need for a nuclear polyhedrosis virus that is specific to S. litura. To date, there have been no reports regarding the responses of S. litura cells to early Spodoptera litura nucleopolyhedrovirus (SpltNPV) infection due to the lack of a reference genome and transcriptome for S. litura. In ...

A critical component for sustaining adequate food production is the protection of local agriculture from invasive pest insects. Essential to this goal is the ability to accurately distinguish foreign from closely related domestic species, a process that has traditionally required identification using diagnostic morphological "keys" that can be both subtle and labor-intensive. This is the case f...

This paper deals with 21 species of Hishimonus Ishihara and two species of Litura Knight from the Indian subcontinent. The following new species are described: Hishimonus acuminatus sp. nov. (India: Mizoram), H. distinctus sp. nov. (India: Karnataka, Kerala, Tamil Nadu. Sri Lanka), H. dwipae sp. nov. (Sri Lanka), H. longisetosus sp. nov. (India: Karnataka), H. spicans sp. nov. (India: Karnataka...

Ascoviruses are double-stranded DNA viruses that are pathogenic to lepidopteran hosts, particularly noctuid larvae. Infection of a larva is characterized by retarded growth, reduced feeding and yellowish body color. In this paper, we reported the growth and development of three major agricultural noctuid insect pests, Helicoverpa armigera (Hübner), Spodoptera exigua (Hübner) and Spodoptera litu...

Field tests were conducted to evaluate the effect of Spodoptera litura (Fab.) nuclear polyhedrosis virus (NPVS) alone and in combination with endosulfan and neemarin (neem seed kernel extract) against S. litura in cabbage. Treatment with NPV-S (500 LE/ha) + Endosulfan (625 ml/ha) was better in reducing the larval population and increasing yield than other treatments. However, considering cost b...

Study of lifecycle patterns and rhythms is important to understand the ecology and evolution of insects. The tobacco cutworm Spodoptera litura (Lepidoptera: Noctuidae), is a serious polyphagous pest in Asia, Oceania and the Indian subcontinent. The laboratory investigations of development patterns and circadian rhythms described in this paper have shown that the development duration from egg to...
