Chilocorus cacti (Coleoptera: Coccinellidae), a potential natural enemy for the red palm mite in Mexico/Chilocorus cacti (Coleoptera: Coccinellidae), enemigo natural potencial del ácaro rojo de las palmas en México

The wild cochineal (Dactylopius opuntiae Cockerell) (Hemiptera: Dactylopiidae) is considered to be the most important pest in cactus pear plantations. In Mexico, there are seven natural enemies that provide natural biological control of D. opuntiae. However, their role and impact have not been evaluated. In this article, we report on aspects of the population biology of Chilocorus cacti L. (Coleoptera: Coccinellidae), which is considered one of the main natural enemies of D. opuntiae. We also conducted experiments to evaluate the consumption of C. cacti by this predator when fed nymphs and adult females of D. opuntiae. Changes in the survival function of D. opuntiae in the presence or absence C. cacti were also identified. Both larvae and adults of C. cacti prefer to consume D. opuntiae nymphs because the wax produced by adult females presents a significant obstacle. The survival analysis showed that the presence of C. cacti had significant negative effects on D. opuntiae survival. C. cacti significantly increased its abundance while reducing the density of adult female D. opuntiae, but this impact occurred only after they had consumed the more preferred nymphs. For this reason, natural enemies other than C. cacti may be required to achieve adequate levels of biological control.

A synopsis of the family Coccinellidae of Colombia is presented, including an annotated list of the species recorded in the country based on published data, a revision of national and foreign collections, and information obtained from citizen science. The list includes 404 species grouped in 81 genera, 21 tribes and two subfamilies. There are 395 native species recorded (among them 201 considered endemic), and nine introduced. For each species, taxonomic information, background on its biology, its usage in biological control and geographic distribution are included. Images of their habitus, living specimens and distribution maps for Colombia and the Americas are also included. Twenty species were recorded for the first time for Colombia, nine for Ecuador, five for Peru and Venezuela, three for French Guiana, two for Brazil and one for Argentina, Cuba, Paraguay, and Puerto Rico, respectively. The coccinellid fauna of Colombia is compared with other countries in South America in terms of the diversity, endemism, and geographical distribution. Two nomenclatural changes are proposed because of homonymy: Hyperaspis amati González is a new name for Hyperaspis mimica Gordon & González, 2011, and Hyperaspis octomaculata González is a new name for Hyperaspis octonotata Gordon & Canepari, 2008.
