“…Hunter, et al (1973) reported that the percentage average of mortality of P. interpunctella that treated with four different concentrations of NPV (8x10 3 , 16x10 3 , 32x10 3 and 64x10 3 PIB) were 12, 19, 24 and 45%. In the case of using GV our results in agreement with Hunter and Hoffmann (1970), who used five different concentrations of GV (12x10 1 , 12x10 2 , 12x10 3 , 12x10 4 and 12x10 5 PIB) on E. cautella. They observed that, the average percentages of mortality were 1, 12, 36, 74 and 100% respectively.…”

The date palm is one of most important fruits in Middle East. Date fruits are exposed to infestation by many insect pests like Ephestia cautella (Walker) and Plodia interpunctella (Hübner) which decrease their quantity and quality. This study aimed to evaluate efficiency of two viruses (NPV and GV) on mentioned these insects. Seven concentrations of each virus were tested (1x10 1 to 1x10 7 ) against these two insects at various durations: 5, 7, and 10 days. Results showed that corrected larval mortality% of E. cautella and P. interpunctella increased by increasing viruses concentrations and exposed durations with highest percentages were 54.44 and 73.33% for E. cautella and P. interpunctella larvae respectively compared with control after treating with NPV virus 1x10 7 for 10 days. While these were 74.33 and 100% for E. cautella and P. interpunctella respectively in case of GV virus compared with control. Data obtained revealed that P. interpunctella larvae were more susceptible to tested viruses than E. cautella larvae. Further, the two insects were more susceptible to GV concentration than NPV concentrations. The corrected mortality percentages of E. cautella and P. interpunctella larvae were increased to 95.56 and 98.89% respectively after using mixture of LC50s of two viruses compared to LC50 of each virus separately. In addition, both viruses exhibited no-effect on tested chemical contents of date's fruits. As a conclusion, combination of both viruses increased their efficacy against E. cautella and P. interpunctella and this has to be considered in biocontrol programs of both insect pests.

Summary I. This review provides a background to those aspects of the biology and behaviour of Lepidoptera infesting stored products which may be important in terms of population dynamics. 2. The general biologies of four common species of Phycitid moth are described. 3. Both the fecundity and the fertility of the adult can be influenced by the diet of the female, the size of the female, the numbers of adults per unit area and a variety of environmental factors. 4. Egg mortality may be caused by sterility or cannibalism. Larval mortality may be caused by starvation or cannibalism. Crowding leads to emigration, reduced size and extended developmental period. Pupal and adult mortalities are of minor importance. Pupae may suffer developmental disorders and adults are killed by spiders and lost by emigration. 5. Parasitoids, predators and diseases, which also contribute to mortality of eggs, larvae, pupae and adults, are described. 6. The importance of planning and sampling in order to obtain detailed data on populations are discussed, together with the analysis of the data. 7. It is shown that Lepidoptera which infest stored products and the parasitoids associated with them have proved convenient experimental tools for the elucidation of certain aspects of population dynamics. A small number of studies have succeeded in identifying the main factors or processes responsible for fluctuation or regulation of the densities of these moths.

“…Nucleocapsids orient in regular arrays along the endoplasmic reticulum and then are inserted individually into envelopes (4). Similar arrays of nucleocapsids closely associated with endoplasmic reticulum have been observed in GV-infected larvae of Plutella xylostella (8) and Cadra cautella (98). There is evidence from studies on NPVs that the initial association of an envelope with a nucleocapsid begins at the capped end of the nucleocapsid (122).…”

“…The crystallization appears to begin either at one side or at one end of the envelope (Fig. 8) and proceeds around the particle (8,98,175,248). Unlike GVs replicated in midgut cells, the majority of enveloped nucleocapsids present in fat body cells FIG.…”
