Arylsulphate and sulphotransferase activities were determined during the late larval development of the southern armyworm. Arylsulphatase titre attains a maximum during the moult and is at a minimum between moults. Sulphotransferase titre appeared to follow the inverse course. A possible enzymic regulatory mechanism for insect steroid hormones is discussed.

The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a harmful pest of many plants. In Egypt, the presence S. in maize fields was reported 2019. aim this study to record parasitoids Egypt. survey conducted at Sohag and Qena governorates. Survey studies showed five were recorded. governorate, from total samples armyworm collected, four species emerged, three them be...

The beet armyworm, Spodoptera exigua (Hübner), is a serious pest worldwide that causes significant losses in crops. Unfortunately, genetic resources for the beet armyworm is extremely scarce. To improve these resources we sequenced the transcriptome of S. exigua representing all stages including eggs, 1(st) to 5(th) instar larvae, pupae, male and female adults using the Illumina Solexa platform...

Conservation and augmentation of indigenous natural enemies are promising strategies for biologically based pest management in outdoor urban environments. This research sought to determine whether the addition of wildßower plantings would enhance the occurrence, abundance and impact of beneÞcial arthropods in the landscape, and to determine the potential compatibility of pest-resistant turfgras...

Abstract Fall armyworm ( Spodoptera frugiperda ), a native insect species in the Americas, is rapidly becoming major agricultural pest worldwide and causing great damage to corn, rice, soybeans, other crops. To control this pest, scientists have accumulated deal of high‐throughput data fall armyworm, nine versions its genomes transcriptomes been published. However, easily accessing performing i...

peribaea tibialis (robineau-desvoidy) and compsilura concinnata (meigen), which are reported for the first time from iran, are solitary parasitoids of rice armyworm larvae, mythimna unipuncta (haworth), in the rice fields of western mazandaran. our studies during 1999-2001 showed that these parasitoids were active on m. unipuncta larvae of different generations, especially 2nd and 3rd generatio...

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 ...
