 injurious to Bees in Cyrenaica.] — L'Agric. colon., Florence, xvi,

Meloe cavensis kills numbers of honey bees in Cyrenaica. In 1918 

 the author observed at Bengasi many dead bees in the hives, and 

 found that the minute larvae of this beetle had penetrated between 

 their abdominal segments. These larvae infested the flowers of 

 Compositae and other plants. It is known that the triungulin larvae 

 of Meloe attach themselves to Hymenoptera, in the nests of which 

 they develop, but there does not appear to be any record of the 

 Hymenoptera being killed. At Bengasi the adult beetles appear in 

 November. After mating in December, the females oviposit in the 

 ground in January and February, from 2,000 to 2,500 eggs being 

 laid by each. The only possible means of countering the attack 

 consists in maintaining very large colonies of bees, as it is only these 

 that can provide sufficient workers to clear away the intruders when 

 they enter the hive. Weak colonies and old queens must be destroyed. 

 A full description of the Meloid larva is given.

In view of statements that Prenolepis fulva, Mayr, is an enemy of 

 Atta sexdens, L., it is pointed out that experiments made in the past 

 by competent observers have shown that this use of P. fulva is of 

 no practical value and cannot be weighed against the losses due to it.
