“…These authors reveal that the interaction may have resulted from the intoxication caused by entomopathogen, inhibiting insect feeding, thus causing stress, and physiological effects, which facilitated fungus penetration in the insect. Similar effects were also observed by Ma et al (2008), when the Cry 1Ac protein of B. thuringiensis was used with B. bassiana. These authors observed deleterious effects in the mortality of larvae of Ostrinia furnacalis (Lepidoptera: Crambidae), besides the decrease in the formation of pupae and emergence of the adult insects.…”

Biological control of pest insects in agriculture is the focus of many studies, because of the risks in the continuous use of synthetic insecticides, which can cause resistant pests or the occurrence of secondary pests. The use of microorganisms like endophytic bacteria has been performed separately or combined with other forms of control in the Integrated Pest Management. Endophytic bacteria live inside host plants, without causing any apparent damage or pathogenicity symptom. Besides performing many functions important to the host, these microorganisms are potentially useful in agriculture, since they are capable of substituting chemical products. By performing biocontrol actions and/or promoting plant growth, these microorganisms are favoring environmental preservation and are thus identified as a viable alternative for ecologically and economically sustainable agricultural production systems. Given the above, this review aimed to present a panorama of the potential application of plant growth-promoting bacteria in the control of pest insects in agriculture, in view of the great biotechnological advances.

“…vittella has attained resistance against many commonly used insecticides and the use of bio-pesticides is one way to overcome this resistance (Gao et al, 2012). The integration (Ma et al, 2008). Further, environmental benign characteristics makes these microbes more suitable in integrated pest management regimes against different insect pests.…”

“…B. thuringiensis was applied mixed in artificial diet and B. bassiana was applied following larval immersion method (Ma et al, 2008). The artificial diet was prepared and shaken in an electric shaker for 30s in a 1 L jug for thorough mixing and even distribution of B. thuringiensis.…”

“…The data for mortality was recorded after every 72 h and the last count noted till pupation for both larval instars. The larvae were disturbed with a blunt needle and those unable to move in a coordinated manner were considered dead (Ma et al, 2008). The data for pupation and adult emergence was also recorded and the emerged adults were allowed to mate freely for egg hatching percentage assessment.…”

“…In number of studies, B. thuringiensis intoxication enhanced the efficacy of B. bassiana especially in case of Lepidopterous insect pests when commercial formulation of B. thuringiensis was combined with B. bassiana (Gao et al, 2012;Wakil et al, 2013). The increasing interest in combining sub-lethal concentrations of B. thuringiensi with B. bassaina has stemmed from their successful control against different insect pests (Ma et al, 2008;Furlong and Groden, 2003).…”

A laboratory strain of Beauveria bassiana sensu lato (Balsamo) Vuillemin (Hypocreales: Clavicipitaceae) and commercial formulation of Bacillus thuringiensis (Berliner) were assessed against three field populations of Earias vittella F. ) were applied alone and in combination against 2 nd and 4 th larval instars. The mortality was observed until pupation. The bioassays were carried out at 25°C and 75% RH The highest larval mortality was observed in the population from Faisalabad with lowest pupation rate, adult emergence and egg eclosion treated with combined concentrations of B. bassiana and B. thuringiensis. The lowest mortality was observed in population from Pakpattan among all the tested populations. Overall results demonstrated that all the treatments gave significant control of E. vittella and both microbial agents may become the integral part of the successful IPM program of E. vittella in okra crop.
