Hello Dear

Field trials with M. a. acridum oil-formulated spores have demonstrated effective control of

S. gregaria(Langewald et al. 1997), Locusta migratoria (L.) and Chortoicetes terminifera (Walker) (Hunter et al. 1999, 2001), Rammatocerus schistocercoides (Rehn)  (Magalhaes et al. 2001) and S. piceifrons  (Hernández-Velázquez et al. 2003). One of the perceived disadvantages, evident in these trials, is the length of time (13 to 14 d) that the target insect takes to die after the application. However, in practical terms, successful control of locust is reflected by reduction in food consumption; a locust that has ceased to feed due to infection is no longer a significant pest (Moore et al. 1992).

Dear colleague,

Some Algerian researchers worked on grasshopers and locusts (Pr. B. Doumandji ENSSA, Alger, F. ACHEUK Unieversity of Boumerdes, Pr. L. Benfekih, University, of Blida, Pr. Ould El Hadj , University of Ouargla) using several alternative methods to neurotixic insecticides. In addition, you can find in researchgate network some relative recent studies (2012) on biological control of grasshopers and locusts from African countries.

Hello,

Please find as attached files two useffull recent papers dealing with 1/ the insect pathogens as biocontrol agents and 2/ with the use of the the sterile insect technique.

Good luck !

Thank you very much.

Please can You send me the two papers Sir Soltani ?

Best regards 

Hello,

Sorry ! Find attached the two papers.

Dear Narimene MATI

I just attached information related to control Locusta migratoria in field. In my hometown, especially in corn plantation, commonly they coming in beginning of rainy season, in end of October every year. So... our farmers always hoeing the soil to destroy their eggs before planting their vegetables and corn. If they attack in the big group, only chemical pesticides to against them. I hope you satisfied.

Thank you. 

Pest management using  biological  means

May be using arthropod/microbes /their products  usually against arthropod or insect pest inspecific .

Dear Hegde ,

Yes , but can you give some examples ?
