Spodoptera litura is a major threat to agricultural crops all over the world including Pakistan. It has developed resistance several chemicals, especially synthetic insecticides. Plant based chemicals like extracts may serve as suitable and alternative biocontrol methods for pests in future. The current study was conducted determine biology of S. on cabbage effects two botanicals i.e. Azadirach...

Volicitin [N-(17-hydroxylinolenoyl)-L-glutamine] has previously been identified from the lepidopteran larval regurgitant as an elicitor of plant volatile emission. The efficient incorporation of free oxygen into volicitin by Spodoptera litura larvae is demonstrated here by rearing them under (18)O(2) for three days. (18)O-labeling of the hydroxyl group of volicitin was confirmed by liquid chrom...

In order to clarify the trapping efficiency of different types sex pheromone traps on populations Spodoptera litura in soybean fields, three kinds conventional traps, called YL-VT, YL-HEMT and YL-NMT, equipped with a automatic catch monitoring mechanism, AIM AIM-lite-A, have been tested. These last two allow diurnal seasonal rhythms catches. From 5 August October 2020, each YL-VT trap caught an...

The immature stages of insects can provide valuable data both for taxonomy and phylogeny, but they are well known only for negligible proportion of the described species. Here we describe lauxaniid immatures for 17 species that were reared under laboratory conditions and subjected to morphological investigation. Following species were included in our study: Cnemacantha muscaria, Homoneura biumb...

BACKGROUND Spodoptera litura is a noctuid moth that is considered an agricultural pest. The larvae feed on a wide range of plants and have been recorded on plants from 40 plant families (mostly dicotyledons). It is a major pest of many crops. To better understand Spodoptera litura granulovirus (SpliGV), the nucleotide sequence of the SpliGV DNA genome was determined and analyzed. METHODOLOGY/...

A study on the effect of weather parameters population dynamics Spodoptera litura (S.litura) in soybean and cotton during kharif season using six years pest data (pheromone trap catches) at Niphad Rahuri Maharashtra showed that rainfall two weeks prior, Tmax Tmin week incidence signifiantly contributed towards occurrence S.litura soybean. Maximum temperature morning humidity one prior were foun...

Spodoptera litura Fabricius pest control using botanical pesticide from papaya leaves extract (PLE) is an alternative to substitute chemical pesticides. The study aimed determine the levels of PLE's activity and evaluate effectiveness PLE different altitudes (low middle lands) cultivars (Thailand Indonesian) against attack S. larvae. An experimental with a randomized block design ( n=5 ) was co...

Armyworm (Spodoptera litura) is an important pest that damages the leaves of soybean. SlNPV one type pathogen has potential as a biocontrol agent to control armyworms because it specific, selective, and effective. This study aimed investigate compatibility between lemongrass in controlling armyworm. The Research was conducted at Laboratory Indonesian Legumes Tuber Crops Institute (ILETRI) from ...

Abstract Background Baculoviruses can be inactivated by ultraviolet (UV) light, which limits their application as an efficient biopesticide. In attempt to enhance virus resistance UV inactivation, a photolyase gene, isolated from Spodoptera litura granulovirus (SpliGV), was expressed in deficient littoralis nucleopolyhedrovirus (SpliNPV) and the infectivity of recombinant expressing phr gene de...

Bioinsektisida merupakan suatu zat organik yang berasal dari makhluk hidup dan berfungsi dalam pengendalian serangan hama pada tanaman. Ulat grayak (Spodoptera litura F.) termasuk banyak menyerang tanaman sayuran, salah satunya pakcoy (Brassica chinensis). Daun Keben mengandung senyawa aktif flavonoid, alkaloid, saponin, tanin bersifat toksik terhadap insektisida. Penelitian ini bertujuan untuk...
